    Endodrelanva siargaoensis 
     Kai, Gorochov, Baroga-Barbecho & Yap, 2019

    Owing to the cryptic behavior and morphology of many Southeast Asian Landrevinae, new species are still being discovered in unexplored parts of the region. Here, we describe a new species: Endodrelanva siargaoensis sp. nov. We also recorded and describe the calling song of the new species. Owing to the morphological similarities between species of Endodrelanva Gorochov, 2000 and Endolandrevus Saussure, 1877, we also provide a short review of the two genera and list their characters for comparison.

    Cyrtodactylus taybacensis
    Pham, Le, Ziegler & Nguyen, 2019

    Taybac Bent-toed Gecko  ||  DOI:  10.11646/zootaxa.4544.3.3 

    We describe a new species of Cyrtodactylus on the basis of seven specimens collected from karst forests of Son La and Dien Bien provinces, Vietnam. Cyrtodactylus taybacensis sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following characters: medium size (SVL up to 97.5 mm); dorsal tubercles in 13–16 irregular rows; ventral scale rows 30–38; ventrolateral folds present without interspersed tubercles; each thigh with 11–13 enlarged femoral scales; femoral pores absent in males and females; precloacal pores 11–13 in males, five or 15 pitted scales in females, in a continuous row; postcloacal tubercles two or three; lamellae under toe IV 16–20; subcaudal scales transversely enlarged; dorsal head with dark brown marking, oval, triangle and arched shape; five brown dorsal bands between limb insertions. In phylogenetic analyses, the new species is recovered as a member of the Cyrtodactylus wayakonei species group, and strongly supported as the sister taxon of C. cf. bichnganae from Son La City in all analyses.

    Microhyla gadjahmadai 
     Atmaja, Hamidy, Arisuryanti, Matsui & Smith, 2018

    A new species of frog in the genus Microhyla is described from Sumatra, Indonesia based on molecular and morphological characters. This new species was previously confused with M. achatina, a Javan endemic. This new species is diagnosable from its congeners by possessing a medium size (SVL in adult males 18.20–21.32 mm, in adult females 20.37–25.51 mm), a stout body, a nostril–eyelid length being about half of the snout length, having a single outer palmar tubercle, a tibiotarsal articulation reaching the center of the eye (when the hindlimbs are stretched and adpressed to the body), having finger and toe tips dilated, having the dorsum with medial longitudinal grooves, and excibiting a very thin and short dark stripe on the temporal region above a wider cream stripe, extending from the postorbital area to insertion of forelimb. Additionally, the new species is characterized by possessing relatively little foot webbing. Uncorrected 16S rRNA sequence divergences between the new taxon and sequences for other congeneric species available ranged from 4.8 to 15.0%.

    Microhyla gadjahmadai sp. nov.
     Synonomy: Microhyla sp. 3: Matsui et al., 2011, p. 168 & 171

    Diagnosis. The new species is assigned to Microhyla because of having a small size (SVL < 30 mm), narrow head and mouth, tympanum hidden by skin, maxillary and vomerine teeth absent, and a reduced first finger length (Tschudi,1838, Malkmus et al.,2002). Microhyla gadjahmadai sp. nov. is diagnosable from its congeners by having a medium size (for Microhyla, SVL adult males 18.2–21.3 mm, adult females 20.4–25.5 mm), stout body, a nostril–eyelid length of half the length of the snout, a single outer palmar tubercle, the tibiotarsal articulation reaching the center of eye, finger and toe tips dilated, median longitudinal grooves on dorsum, relatively reduced toe webbing (free of webbing: one and three quarter phalanges on outer surface of second toe, three phalanges on inner and outer surface of third toe, four phalanges on inner and outer surfaces of fourth toe, and two and three quarter phalanges on inner surface of fifth toe), and a thin-short dark temporal stripe over a wider cream stripe, extending from postorbital area to insertion of forelimb.

    Etymology. The specific epithet honors the military leader and hero Gadjah Mada, who in the fourteenth century unified the whole of the Nusantara (i.e., Malay Archipelago) under the Javanese rule of the Hindu Majapahit Empire.

    Natural history. Microhyla gadjahmadai sp. nov. is distributed in southern Sumatra, inhabiting from primary forest, secondary forest and open area such as farming area (Bengkulu). The tadpole and advertisement call of this species are still unknown.

    Range. The new species is curently known from Bengkulu (Rejang Lebong, Bengkulu Utara, and Kepahiang Regency), Lampung (Tanggamus and Lampung Tengah Regency), and South Sumatra (Muara Enim Regency and Pagar Alam City) province with elevation range from 700–1647 m a.s.l.

     Fejervarya marathi 
    Phuge,Dinesh,Andhale,Bhakare & Pandit, 2019

    Marathi Fejervarya Frog  ||  DOI: 10.11646/zootaxa.4544.2.5 

    In the recent past the systematic position and taxonomy of genus Fejervarya, Bolkay is undergoing changes in its systematic position due to fairly good amount of phylogenetic resolution, cryptic morphological characters and lack of systematic sampling for phylogenetic studies across the range of distribution. In our sampling in the northern Western Ghats, we encountered a new lineage sister to the phylogenetic cluster which comprises the 'Rufescens complex'. This new lineage is described here as new species Fejervarya marathi sp. nov. based on distinctness in a combination of morphological characters, genetic distance and geography. The problems in morphological groupings for the Fejervarya frogs of the Western Ghats in the recent studies are discussed with the sub-clade composition based on geography in the phylogenetic tree.

    Keywords: Amphibia, Cryptic species, Fejervarya, Marathi, northern Western Ghats

    Fejervarya marathi sp. nov., amplecting pair. 

    Fejervarya marathi sp. nov.

    Etymology. The specific epithet is derived from the indigenous language "Marathi" which is one of the predominant language used in the northern Western Ghats. The species epithet is treated as noun in apposition to the generic name. Suggested common name 'Marathi Fejervarya frog'.

     Campodonico & Fierro, 2019

    Pseudoamycle polylepisae gen. et sp. nov. is described from northernmost Chile (Arica and Parinacota Region). It is characterized by the small and brown body, head with no preocular flange, cephalic process porrect and dorsoventrally compressed, dorsal surface from lateral view not angulate at level of eyes, eyes round, tegmina concolorous and vein MP of tegmen pectinate. The new taxon was found to be associated with Polyepis rugulosa Bitter (Rosaceae).

    Lacunicambarus diogenes (Girard 1852) was, until recently, considered to be one of the most widely distributed North American crayfish species, occurring in 31 U.S. States and one Canadian province east of the North American Rocky Mountains. Glon et al. (2018) investigated this claim and found that L. diogenes sensu lato was actually a species complex. The authors redescribed L. diogenes and restricted its range to the Atlantic Coastal Plain and Piedmont ecoregions of eastern North America. In doing so, they also revealed the existence of several probable undescribed species of Lacunicambarus that were previously considered to be L. diogenes. Here, we use morphological and molecular techniques to distinguish and describe one of these species: Lacunicambarus chimera sp. nov., a large primary burrowing crayfish found in parts of the Lower Mississippi, Ohio, Tennessee and Upper Mississippi River Basins. Lacunicambarus chimera is morphologically similar to L. diogenes, from which it can be distinguished by the greater number of spines on the ventrolateral margin of its merus, its wider antennal scale terminating in a short spine, and the presence of a single longitudinal stripe on the dorsal side of its abdomen. We also provide an updated key to Lacunicambarus.

Acumen distinctly delimited basally by 45° angles. Cephalothorax cylindrical, with 3–10 (mean ± sd: 6 ± 1) small tubercles lining posterior margin of cervical groove. Anteroventral branchiostegal tubercles small, numbering 8–29 (mean ± sd: 18 ± 4). Suborbital angle acute. Postorbital ridges developed, lacking anterior spine or tubercle. Areola obliterated, constituting, in adults, 38–45% (mean ± sd: 42 ± 0 %) of entire length of cephalothorax. Antennal scale 2.41 to 3.35 (mean ± sd: 2.80 ± 0.18) times as long as wide, broadest distal to midlength, terminating in small spine, mesial margin forming straight edge. Dorsomesial margin of palm of chelae with 3 rows of tubercles, mesial-most row normally consisting of 6–10 (mean ± sd: 7 ± 1) probolos tubercles, running parallel to second row with 4–9 (mean ± sd: 6 ± 1) probolos tubercles, third row running diagonally from mesial base of palm to lateral dactyl articulation in the form of 5–8 (mean ± sd: 7 ± 1) subprobolos tubercles located in shallow dimples. No tufts of elongated setae at mesial base of fixed finger. Opposable margin of dactyl weakly concave at base. Ratio of dactyl length to palm length 1.78–2.49 (mean ± sd: 2.10 ± 0.16). Dorsomedian longitudinal ridges of dactyl and fixed finger of propodus weakly developed. Dorsolateral impression at base of propodus moderate. Ventral surface of chelae with 0–5 (mean ± sd: 2 ± 1) subpalmar tubercles. Mesial margin of dactyl with 12–33 (mean ± sd: 22 ± 4) prominent tubercles. Ventral surface of carpus with single spine on mesial articular rim, mesial margin with 4–10 (mean ± sd: 7 ± 1) spines of varying sizes. Merus spines numbering 2–9 (mean: 5 ± 2) on ventrolateral margin and 7–16 (mean ± sd: 11 ± 2) on ventromesial margin. Mesial ramus of uropod with distomedian spine not reaching caudal margin. Gonopods of Form I males contiguous at base, with moderately pronounced umbo near midlength of caudal surface; terminal elements consisting of 1) short, tapering, distally truncate central projection lacking subapical notch, shorter than mesial process, directed caudally at approximately 90°, reaching past margin of umbo, 2) mesial process with conical base tipped with protruding finger, directed caudally at approximately 90° and overreaching umbo by noticeable amount and 3) inconspicuous caudal knob sometimes present at caudolateral base of central projection. Hooks on ischium of third pereiopods only. Female with annulus ventralis subquadrangular or kiteshaped, approximately as long as wide, rather deeply embedded in sternum, flexible, with posterior half sclerotized and anterior half mildly pliable.

    Ecological Notes. As mentioned above, Lacunicambarus chimera is a primary burrowing crayfish species. Like other Lacunicambarus species, L. chimera is commonly dug from burrows in fine-grained soils along the floodplains of streams and rivers and in roadside ditches. We have also collected this species in burrows on the banks of manmade ponds and in ditches that were lined with large stones. The chimneys at the mouths of L. chimera burrows are often large and conspicuous, attaining heights of 30 cm or more. These burrows, like those of other primary burrowing crayfishes, provide habitat for many other organisms (e.g., Creaser 1931; Pintor & Soluk 2006; Thoma & Armitage 2008). Glon & Thoma (2017) specifically documented the use of L. chimera burrows as brooding burrows by eastern cicada killer wasps in Pike County, Indiana. 

    Little is known about the ecology of L. chimera in situ, but specimens which we have kept in laboratory aquariums have readily consumed a variety of aquarium fish foods, snails, earth worms, and leaf litter from streams, suggesting that this species is an opportunistic omnivore. These specimens were mostly active at night, when they foraged around their enclosures. During the day, they rested inside of artificial burrows made from PVC pipes, occasionally twitching their antennae in response to stimuli. They did not appear to be particularly aggressive, compared to other crayfish species.

    Crayfish Associates. We collected the following primary and secondary-burrowing crayfishes from burrows at sites where we found Lacunicambarus chimera: Creaserinus fodiens (Cottle 1863), C. hortoni (Hobbs & Fitzpatrick 1970), Faxonius immunis (Hagen 1870), L. ludovicianus, L. polychromatus, L. aff. polychromatus, Procambarus acutus (Girard 1852), P. clarkii (Girard 1852), P. gracilis (Bundy in Forbes 1876) and P. viaeviridis (Faxon 1914). While sampling for L. chimera, we focused primarily on sampling for burrowing crayfishes and therefore do not have records of the tertiary-burrowing crayfishes that undoubtedly inhabit open water adjacent to L. chimera burrows. 

    Etymology. Our choice of the species epithet “chimera” stems from our first encounter with this species. The first specimens that we caught were freshly molted young adults (approximately 30 mm CL). These specimens bore a bright longitudinal gladiate stripe reminiscent of the stripe in L.ludovicianus, L. miltus, and some populations of L. polychromatus. The bright colors on these specimens were similar to those found in L. polychromatus, and the general shape of these specimens was reminiscent of L. diogenes. These features made L. chimera appear to be a chimera of multiple Lacunicambarus species. To honor the nickname given to this species when it was first discovered by Ray Jezerinac and Whitney Stocker, and also as a reference to its impressive size, we suggest the common name “Crawzilla Crawdad.”

    Neocaridina fonticulata  
    Shih, Cai & Chiu, 2019

    A new species of land-locked freshwater shrimp, Neocaridina fonticulata sp. n. (Atyidae), is described from Kenting, Hengchun Peninsula, Pingtung County, southern Taiwan. This new species can be distinguished from its congeners by rostrum structure, pereiopods, and male first and second pleopods. The molecular evidence of mitochondrial cytochrome oxidase subunit I (COI) also supports the establishment of a new species. This is the third endemic species of Neocaridina known from Taiwan.

Scale bars: 1.5 mm (A); 0.5 mm (B, E–J); 1 mm (C, D) (male, cl 3.0 mm, paratype, ZRC 2018.1013).

    Diagnosis: Rostrum short, straight, slightly sloping downwards, reaching mostly to end of 1st segment of antennular peduncle, rostral formula 1–3+8–15/1–4. Pterygostomian margin armed with an indistinct spine. 1st pereiopod carpus 1.2–1.5 × as long as high; chela 2.0–2.1 × as long as broad; fingers slightly longer than palm. 2nd pereiopod carpus 1.1–1.2 × as long as chela, 3.9–4.3 × as long as high; chela 2.1–2.3 × as long as broad; fingers 1.3–1.4 × as long as palm. 3rd pereiopod with propodus straight in females, slightly incurved in males, 2.7–3.0 × as long as dactylus; dactylus terminating in two claws, 4–6 accessory spines on flexor margin, strongly incurved in males. 5th pereiopod propodus 2.7–2.8 × as long as dactylus, dactylus terminating in one claw, with 46–54 spinules on flexor margin. Endopod of male 1st pleopod extending to 0.8 × exopod length, inflated at distal ¾, pyriform, 1.7 × as long as wide, appendix interna at base of inflated part, short. Appendix masculina of male 2nd pleopod cylindrical, reaching to 0.7 length of endopod, appendix interna reaching to 0.6 length of appendix masculina. Uropodal diaeresis with 13–14 movable spinules. Eggs 1.10 × 0.68 to 1.20 × 0.75 mm in diameter.

    Etymology: Neocaridina fonticulata is named after its known habitat, from the Latin root, fonticulus, for little spring.

    Ecological notes: Specimens of the new species were collected from leaf litter layer of a small stream (Figure 4E, F) next to a spring outlet at a limestone hill. The collection site consists of concretized substrate and banks, representing the headwater of the stream. The water flow is slow, cool temperature (about 25 °C), neutral (pH 7.06–7.16), and with moderately high dissolved oxygen (7.33–7.70 mg/L). The freshwater crabs, Candidiopotamon rathbuni (De Man, 1914) and Geothelphusa ferruginea Shy, Ng & Yu, 1994, were found to be sympatric with this new species. Ovigerous females were found in July.

    Distribution: Presently known only from Sheding, Kenting, southern Taiwan.

    Enyalius capetinga
    Breitman, Domingos, Bagley, Wiederhecker, Ferrari, et al., 2018.

    We describe a new species of Enyalius endemic to the Brazilian Cerrado, based on morphological and molecular data sets. In the face of uncertain taxonomy among museum specimens of Enyalius, we used a novel analytical approach based on Gaussian mixture modeling for species assignments. We also used a machine-learning classification procedure (random forests) to investigate morphological variation and identify species diagnostic characters. Phylogenetic and species delimitation analyses supported the distinction of the new species from its congeners. The new species is characterized by the fewest ventral scales and smallest snout–vent length in the genus. Moreover, we infer that this species diverged from its closest relative, E. bilineatus, in the late Miocene, presumably after colonization of Cerrado gallery forests by an Atlantic Forest ancestor, followed by ecological or geographical speciation linked to shrinkage or fragmentation of gallery forests associated with global cooling and increased aridity. Rapid conversion of natural habitats, the isolation of protected areas, and recent changes to the Brazilian Forest Code pose serious threats to the conservation of the new species described herein, and other gallery forest inhabitants.

    Citharexylum peruvianum  N.O’Leary & Frost

    in O'Leary & Frost, 2018. 

    A new species of Citharexylum from the foothills of inter-Andean dry valleys in Peru, Citharexylum peruvianum, is described and illustrated herein. It is distinguished from other closely related species with caulinar spines (C. andinum, C. flexuosum, C. herrerae, C. montevidense, and C. weberbaueri), by inflorescence morphology, leaf size, and pubescence. The newly defined taxon has 15–40 flowered racemes, rachis 7–12 cm long, and coriaceous leaves, with the leaf blade being 4–6(8) × 2–3 cm and densely hirsute on the abaxial surface. A brief discussion on closely related species is provided. Citharexylum peruvianum is known exclusively from northwestern Peru, from the departments of Cajamarca, Lambayeque, and La Libertad. The species grows in the Andean foothills at mid-elevations between 1400 and 3000 m a. s. l., in rocky soils and on steep slopes with thorny scrubland. It is occasionally found in moist areas. This species has a restricted distribution and limited numbers of individuals, which will likely result in threatened status following formal review.

    A new saxicolous species of Amaryllidaceae tentatively assigned to the tribe Clinantheae, Pamianthe ecollis Silverst., Meerow & Sánchez-Taborda, is described from the western slope of the Cordillera Occidental in the department of Cauca, Colombia. The new species differs from the two hitherto known species of Pamianthe in its yellow flowers and in its nearly obsolete perianth tube. The near loss of the perianth tube may be correlated with a change in pollinator. The new species lacks a bulb; it produces a large number of winged seeds that are wind-dispersed. A key to the species of Pamianthe is provided. This is the first record of the genus Pamianthe for Colombia. The phylogenetic position of the genus Pamianthe is discussed.

    Pamianthe ecollis Silverst., Meerow & Sánchez-Taborda, sp. nov.

    Diagnosis: This species differs from both Pamianthe parviflora Meerow and P. peruviana Stapf in having a yellow perianth and staminal cup (versus white) and in nearly lacking a perianth tube. Additionally, it differs from P. parviflora in having shorter pedicels, a longer ovary, and more numerous ovules, and from P. peruviana in having much longer pedicels, more flowers per umbel, much shorter tepals, a shorter staminal cup that is not exserted from the perianth, and a smaller fruit.

    Etymology: The specific epithet is from Latin, e (without), collum (neck), adjectival collis, referring to the almost absent perianth tube of this species.

    Resumen: Se describe una nueva especie de Amaryllidaceae tentativamente perteneciente a la tribu Clinantheae, Pamianthe ecollis Silverst., Meerow & Sánchez-Taborda, procedente de la vertiente occidental de la cordillera Occidental en el departamento del Cauca, Colombia. La nueva especie difiere de las dos especies conocidas de Pamianthe por su perianto amarillo que tiene un tubo casi ausente. La reducción del tubo del perianto probablemente tiene correlación con un cambio en el polinizador. La nueva especie carece de un bulbo, y produce numerosas semillas aladas que se dispersan por el viento. Se provee una clave a las especies de Pamianthe. Este es el primer registro del género Pamianthe para Colombia. Se discute la posición filogenética del género Pamianthe.

    Photomontage of OroBOT and reconstructed Orobates pabsti 

    Nyakatura, Melo, Horvat, et al., 2019. 

    Reconstructing the locomotion of extinct vertebrates offers insights into their palaeobiology and helps to conceptualize major transitions in vertebrate evolution. However, estimating the locomotor behaviour of a fossil species remains a challenge because of the limited information preserved and the lack of a direct correspondence between form and function. The evolution of advanced locomotion on land—that is, locomotion that is more erect, balanced and mechanically power-saving than is assumed of anamniote early tetrapods—has previously been linked to the terrestrialization and diversification of amniote lineages. To our knowledge, no reconstructions of the locomotor characteristics of stem amniotes based on multiple quantitative methods have previously been attempted: previous methods have relied on anatomical features alone, ambiguous locomotor information preserved in ichnofossils or unspecific modelling of locomotor dynamics. Here we quantitatively examine plausible gaits of the stem amniote Orobates pabsti, a species that is known from a complete body fossil preserved in association with trackways8. We reconstruct likely gaits that match the footprints, and investigate whether Orobates exhibited locomotor characteristics that have previously been linked to the diversification of crown amniotes. Our integrative methodology uses constraints derived from biomechanically relevant metrics, which also apply to extant tetrapods. The framework uses in vivo assessment of locomotor mechanics in four extant species to guide an anatomically informed kinematic simulation of Orobates, as well as dynamic simulations and robotics to filter the parameter space for plausible gaits. The approach was validated using two extant species that have different morphologies, gaits and footprints. Our metrics indicate that Orobates exhibited more advanced locomotion than has previously been assumed for earlier tetrapods7,9, which suggests that advanced terrestrial locomotion preceded the diversification of crown amniotes. We provide an accompanying website for the exploration of the filters that constrain our simulations, which will allow revision of our approach using new data, assumptions or methods.

    Spathochaeta octopodis
    Jimi, Moritaki & Kajihara, 2019

    Marine annelids in the subfamily Calamyzinae (family Chrysopetalidae) are either symbiotic or free-living forms that have been mainly reported from deep-sea chemosynthetic systems. Symbiotic calamyzines mainly live in the mantle cavity of bivalves in hydrothermal vents or cold seeps, but one species is also found to be inserted into the epidermis of polychaetes. We found a single specimen of calamyzine polychaete on the body surface of Octopus sp. collected in the Sea of Kumano (Japan), which represents the first known record of symbiotic association between polychaetes and octopuses. We described the specimen as Spathochaeta octopodis gen. et sp. nov. Spathochaeta gen. nov. can be discriminated from other genera in Calamyzinae by the presence of spatula-shaped notochaetae and dorsal chaetal lobes. We also provided the phylogenetic position of S. octopodis gen. et sp. nov. within Chrysopetalidae based on four gene markers (COI, 16S, 18S, H3).

    Calamyzinae Hartmann-Schröder, 1971 

    Spathochaeta gen. nov. 
    [New Japanese name: tako-yadori-gokai-zoku]

     Type species: Spathochaeta octopodisgen. et sp. nov.

     Etymology: The new genus name, feminine in gender, derives from the Latin spatha (spatula) and chaeta (mane, hair), referring to the spatula-shaped notopodial chaetae, which are characteristic for the new genus. 

    Remarks: Within Calamyzinae, notopodia having notochaetae are found not only in Spathochaeta but also in Boundemos Watson et al., 2016; Microspina Watson et al., 2016; and Vigtorniella Kiseleva, 1992 (Aguado et al., 2013; Kiseleva, 1992; Watson et al., 2016). Spathochaeta differs from these three genera in having dorsal chaetal lobes and simple spatular chaetae on notopodia. The molecular analysis indicated the new genus is sister to Calamyzas Arwidsson, 1932 (see 'Molecular analysis' sectionbelow). The new genus can be discriminated from Calamyzas by the following features: (i) absence of dorsal lobe; (ii) absence of notochaeta; (iii) having only one type of chaeta (compound chaeta) (Aguado et al., 2013).

     Spathochaeta octopodis gen. et sp. nov. 
    [New Japanese name: tako-yadori-gokai]

    Etymology: The new specific name is a noun in the genitive case of the Latin octopus, indicating the host organism of the new species. 

    Habitat: Spathochaeta octopodis gen. et sp. nov. was collected from the external body surface of Octopus sp. (Fig. 1). Our observation that the living specimen of S. octopodis kept attaching on the octopus’ body surface for three days strongly supports a symbiotic relation between the species and the octopus, instead of an accidental attachment. When alive, the worm was observed to move around from the mantle to web of the host octopus. However, further findings and observations on the behaviour of the species are required to confirm the postulated symbiotic association. The octopus was collected from off Owase, the Kumano Sea, off central Japan, eastern North Pacific, 150 m depth.

    Diploderma drukdaypo 

    Wang, Jiang, Ren, Zou, Wu, Che & Siler, 2019

    Japalura drukdaypo

    Despite being recognized as ecologically and biogeographically important, the biodiversity of the Hengduan Mountain Region, particularly along the upper Mekong River, remains poorly understood. Here we describe a new species of Mountain Dragon of the genus Japalura sensu lato Gray, 1853 from the headwater region of the Mekong River in Chamdo, Tibet Autonomous Region, China. The species is recognized as a member of the Japalura flaviceps Barbour & Dunn 1919 complex, and it can be distinguished readily from all congeners by a suite of morphological characteristics, including its dwarf appearance (small body size and disproportionally short tails and short hind limbs), smooth or weakly keeled ventral scales, feebly developed vertebral crests in males, and by the absence of distinct gular spots in males and females. In addition to the description of the new species, we also report morphological variations and range extensions of two recently described congeners along the same river, namely J. iadina and J. vela. We discuss the distribution patterns of the genus in the Hengduan Mountain Region and the urgent conservation priorities for protecting Japalura species along the Mekong River. According to our best available data, we provided IUCN assessments of the three species and propos to list them as nationally protected under the Chinese Wildlife Protection Act.

    After almost two years, our manuscript finally gets published! A new species of dwarf Japalura sensu lato, Japalura drukdaypo (was still Japalura when we first submitted it, and now it should be Diploderma after our generic revision) from the upper Mekong River Valley in eastern Tibet, China. The species name, drukdaypo, is derived from Kham Tibetan, which means "dwarf dragon".

    Blue Teays Mudbug  ||

    A new species of crayfishCambarus loughmani sp. nov., is described from the preglacial Teays River Valley of Cabell, Kanawha, Lincoln, Mason, and Putnam counties, West Virginia. The species was previously considered to be part of the Cambarus dubius complex. Loughman et al. restricted C. dubius to an orange colour morph found in central and northern portions of the Allegheny Mountains and Appalachian Plateau in central West Virginia, western Maryland, and south-central Pennsylvania. The new species described herein can be distinguished from all other members of Cambarus Erichson, 1846 by a double row of cristiform tubercles on the palm, an open areola with two rows of punctations, and a consistent blue colouration.

    Etymology: The authors of this paper name this crayfish in honour of Dr Zachary J. Loughman, assistant professor of biology, West Liberty University. In recent years, prior to the naming of this species, Dr Loughman has served as one of the primary astacological researchers, contributing greatly to our understanding of ecology, taxonomy, conservation and distribution of Appalachian crayfish species. It is fitting that this crayfish be named in his honour, as both he and this crayfish are reclusive, hard to track down, and when faced with adversity never back down and often advance with arms flailing. The authors of this paper are composed of a mix of age classes. For the younger authors, Dr Loughman has served as a teacher, advisor and mentor. For the older authors he has served as a colleague, collaborator and student. For all of us, he has been a friend and an inspiration. Common name:The suggested common name for this species is Blue Teays Mudbug as it inhabits the Teays River Valley.

    A new species of Cnemaspis Strauch, 1887 is described from Nilgala Savannah Forest in Sri Lanka. The new species is diagnosed from all other congeners by the following suite of characters: small body size (SVL< 33 mm), dorsal scales on trunk homogeneous, one pair of post mentals separated by a single small chin scale, ventral scales on trunk smooth, subimbricate, 17–19 scales across the belly. Subdigitals scansors smooth, entire, unnotched; lamellae under digit IV of pes 17 –18. Males with femoral pores on each thigh but lacking precloacal pores. Median row of subcaudals smooth, subimbricate, enlarged and in an irregular series of subhexagonal scales. This new species had been previously confused with Cnemaspis alwisi Wickramasinghe & Munidradasa, 2007. The new species differs from Cnemaspis alwisi by having 122–129 ventral scales (versus 146–152), 7–8 supralabials (versus 8–10), and relatively shorter SVL ranging between 31.5–32.9 mm (versus 37.8–39.9 mm). Further, the new species is genetically divergent from Cnemaspis alwisi, the species that it closely resembles by 13.5% and 7.8% from its sister species in the ND2 gene. The present discovery highlights the need for dedicated herpetofaunal explorations in Sri Lanka, especially the intermediate bioclimatic zone and associated cave systems and rock outcrops.

    Uroplatus finaritra 
    Ratsoavina, Raselimanana, Scherz, Rakotoarison, Razafindraibe, Glaw & Vences, 2019

    The Marojejy Massif in northern Madagascar is a constant source of herpetological surprises. Herein we describe a new species of leaf-mimicking leaf-tailed gecko, Uroplatus finaritra sp. nov., based on morphological and molecular phylogenetic evidence. This new species inhabits the rainforests of Marojejy National Park at low elevations and is morphologically similar to Uroplatus phantasticus, but differs by having a larger body size, relatively shorter tail, and dark-red pigmentation of the oral mucosa. Molecular data reveals a distance of 14.0–14.7% in the 16S rRNA gene to U. phantasticus, and haplotype sharing in the c-mos nuclear gene only with species of much shorter tails (i.e., with U. kelirambo and two undescribed candidate species). Similar to other members of the leaf-mimicking Uroplatus species in northern Madagascar, Uroplatus finaritra sp. nov. likely has a small geographic distribution, and is currently known only from the lowland rainforests of Marojejy. We discuss the value of the buccal mucosa colouration and tail dimensions of Uroplatus as taxonomic characters, and the potential drivers of their evolution. In order to reduce the risk of international trade under incorrect species names we suggest that exported CITES species should be obligatorily accompanied by information about their precide geographic origin within Madagascar.

    Etymology. Finaritra is a Malagasy word for special greetings but also means healthy and happy. We refer to our delight in describing this splendid and exceptionally large species from a clade of generally small-sized leaf-tailed geckos. The name is an invariable noun in apposition.

    Resumé:Le massif de Marojejy au nord de Madagascar, représente constamment une source de surprises herpétologiques, avec la découverte d'une nouvelle espèce de gecko à queue plate. Les résultats des analyses phylogénétiques et morphologiques ont permis la description de Uroplatus finaritra sp. nov. Cette nouvelle espèce habite les forêts humides de basse altitude de Marojejy et est morphologiquement similaire à Uroplatus phantasticus. Néanmoins, elle diffère de cette dernière par un corps plus grand, une queue relativement plus courte et une pigmentation rouge foncée de la muqueuse buccale. Les données moléculaires révèlent une distance de 14,0 à 14,7% pour le gène 16S rRNA par rapport à U. phantasticus. Le partage d’haplotypes pour le gène nucléaire c-mos ne se présente qu’avec les espèces à queue beaucoup plus courte tel que U. kelirambo et deux autres espèces candidates non décrites. Vue la présence de plusieurs formes similaires de gecko A queue aplatie dans la partie nord de Madagascar, Uroplatus finaritra a probablement une distribution restreinte, étant recensée uniquement dans la zone de basse altitude du massif de Marojejy. Afin de réduire le risque de la commercialisation des espèces au niveau international sous des noms incorrects, il est suggéré que les espèces CITES exportées soient obligatoirement accompagnées d'informations concernant leur origine géographique précise à Madagascar.

Genera Buloria Distant (new placement), Crispina Distant (new placement) and Myittana Distant (new placement) are placed in the tribe Mukariini. Genus Mohunia is redefined based on the study of its type species. Benglebra Mahmood & Ahmed 1969 is synonymised with Myittana Distant 1908 and considered as its subgenus. Myittana (Benglebra) alami (Mahmood & Ahmed) comb. nov., Myittana (Savasa) bipunctata (Mahmood & Ahmed) comb. nov.. Myittana (Benglebra) introspina (Chen & Yang 2007) comb. nov. and Mukariella bambusana (Li & Chen) comb. nov. are proposed; the first two species were earlier placed in the genus Benglebra, the third species in the genus Mohunia and the fourth in the genus Mukaria. Genera Flatfronta Chen & Li and Myittana are new records for India and Scaphotettix striata Dai & Zhang is a new record for the Indian subcontinent and Sri Lanka. All taxa dealt with are described and illustrated and keys for genera and their species are also given.

(eastern Indonesia and New Guinea): A. arfak sp. n., A. tinoor sp. n., A. manokwari sp. n., A. meja sp. n., A. tolire sp. n.; and one new species in Chisosa Huber, 2000: C. caquetio sp. n. (Netherlands Antilles). In Ninetinae, three new monotypic genera are described: Pemona gen. n., with the type species P. sapo sp. n. (Venezuela); Pinocchio gen. n., with the type species P. barauna sp. n. (Brazil); andMagana gen. n., with the type species M. velox sp. n. (Oman). In Modisiminae, three new species are described in Chibchea Huber, 2000 (all from Brazil):C. amapa sp. n., C. santosi sp. n., andC. hamadae sp. n.; one new species in Psilochorus Simon, 1893: P. bromelicolus sp. n. (Brazil); and three new monotypic genera, all from Brazil: Arenita gen. n., with the type species A. fazendinha sp. n.; Kairona gen. n., with the type speciesK. selva sp. n.; and Saciperere gen. n., with the type species S. catuaba sp. n. In Pholcinae, a new monotypic genus is described: Giloloa gen. n., with the type species G. sofifi sp. n. (Indonesia); three new species in the genus Aetana Huber, 2005 (all from Indonesia): A. ternate sp. n.;A. mokwam sp. n.;A. ondawamei sp. n.; and two new species in the genus Panjange Deeleman-Reinhold & Deeleman, 1983 (both from Indonesia):P. thomi sp. n., andP. togutil sp. n.

    Artema ghubrat is a cave-dwelling species and the only (slightly) troglomorphic representative of Arteminae; A. dhofar is presumably the closest known relative of the pantropical and synanthropic A. atlanta. The new genus Arnapa is probably species rich in eastern Indonesia and New Guinea but poorly collected; its morphological delimitation from other Australasian Arteminae (Wugigarra Huber, 2001; Holocneminus Berland, 1942; Trichocyclus Simon, 1908) needs further study. Arnapa nigromaculatus (Kulczyński, 1911) comb. n. is newly transferred from Psilochorus. Pemona sapo is the first representative of Ninetinae from Venezuela. The genus Chibchea, previously known from the Andes only, is for the first time recorded from Brazil/lowland Amazonia. Arenita fazendinha is among the few species in Pholcidae with extremely reduced procursus and barely modified male chelicerae. Kairona selva is unique among Pholcidae for its brush of strong hairs on a median horn anteriorly on the ocular area. Saciperere catuaba is one of only four pholcid species currently known to occur both in the Amazon and in the Atlantic Forest; however, variation indicates that more than one species might be included. It is among the few spiders known to have asymmetric genitalia (antisymmetric female internal genitalia). The Brazilian Psilochorus bromelicolus is the first South American Psilochorus of which both sexes are adequately described; however, the assignment to Psilochorus is tentative. Aetana ternate has extremely elongated procursi and accordingly elongated female internal genitalia. Aetana ondawamei and A. mokwam have almost identical male pedipalps and chelicerae (except for size) but differ clearly in the female genitalia.

    Cryptic diversity corresponding with island of origin has been previously reported in the endemic, geographically restricted sooglossid frogs of the Seychelles archipelago. The evolutionary pattern behind this has not been fully explored, and given current amphibian declines and the increased extinction risk faced by island species, we sought to identify evolutionarily significant units (ESUs) to address conservation concerns for these highly threatened anurans. We obtained genetic data for two mitochondrial (mtDNA) and four nuclear (nuDNA) genes from all known populations of sooglossid frog (on the islands of Mahé, Praslin and Silhouette) for phylogenetic analyses and to construct nuDNA haplotype networks. Bayesian and maximum likelihood analyses of mtDNA support the monophyly and molecular differentiation of populations in all species that occur on multiple islands. Haplotype networks using statistical parsimony revealed multiple high-frequency haplotypes shared between islands and taxa, in addition to numerous geographically distinct (island-specific) haplotypes for each species. We consider each island-specific population of sooglossid frog as an ESU and advise conservation managers to do likewise. Furthermore, our results identify each island lineage as a candidate species, evidence for which is supported by analyses of mtDNA based on Bayesian Poisson tree processes, and independent analyses of mtDNA and nuDNA using the multispecies coalescent. Our findings add to the growing understanding of the biogeography and hidden diversity within this globally important region.
