Lapidia apicifolia  Roque & S.C. Ferreira
   
Abstract

Asteraceae is the family with the highest species number in the rocky fields (campos rupestres) of the Chapada Diamantina, Bahia, Brazil. On the basis of several collections from this area, we are proposing a new genus of Asteraceae based on morphology and phylogeny, to accommodate a species newly described here. Lapidia apicifolia is a loosely ramified shrub 2–4 m high, stem tomentose, leaves opposite-decussate, laminae conduplicate, petiolate, receptacle flat, epaleaceous, glabrous, and pappus of bristles fused at base, irregular in length, fringed and purplish. In a phylogenetic analysis using sequence data from ITS and trnL-trnF of selected members of Eupatorieae, Lapidia is indicated as sister group of a highly supported clade with Morithamnus, Bahianthus and Catolesia. This group is composed by loosely branched shrubs, most with leaves that are lax, stems, leaves and involucral bracts that are viscid (Bahianthus and Morithamnus) and, if not, trichomes (tomentose indumentum) are developed (Lapidia), to protect against both solar radiation and loss of water. A description, illustrations, and a discussion about related and sympatric genera are presented.

Vietnamella sinensis  (Hsu, 1936)

Abstract

The genus Vietnamella Tshernova, 1972 is reviewed and 3 valid species are confirmed. They are V. ornata (Tshernova, 1972), V. sinensis (Hsu, 1936)(=V. dabieshanensis You & Su, 1987, new synonym; =V. qingyuanensis Zhou & Su, 1995, new synonym; =V. guadunensis Zhou & Su, 1995, new synonym) and V. thani Tshernova, 1972. The nymphal and key imaginal characters of V. sinensis are described and figured. The monogeneric family Vietnamellidae has long series of autapomorphies (two pairs of projections on head, modified mandibles, slender maxillae with few setae, round hindwings, and half of egg covered with single cap) and some plesiomorphies (seven pairs of gills, large hindwings, few marginal intercalaries on forewings). The structures of mouthparts, head and forefemora suggest that nymphs of Vietnamella may be able to move substrates and scrape food from them. Morphological evidences show that the family Vietnamellidae is a basal clade of Ephemerelloidea.

Rodrigues, Recoder, Teixeira, Roscito, Guerrero, et al., 2017


Abstract
The lizard genus Psilophthalmus was originally described from the sandy deposits at the northern end of Serra do Espinhaço, in Santo Inácio, state of Bahia, but since then it has been recorded in other Brazilian localities of the states of Bahia, Minas Gerais, and Sergipe. Here, we review the collected specimens based on molecular markers (mitochondrial 12S, 16S, ND4 and cyt b, and nuclear C-mos and NT3) and morphological evidence (external, hemipenial and osteological morphologies). In the course of our revision we find out that Psilophthalmus Rodrigues 1991 was preoccupied by Psilophthalmus Szépligeti 1902 (Hymenoptera, Braconidae). The replacement name Psilopsis proposed for the genus for which we recognize three species, with Psilops paeminosus as type species. One of the new species is found along the high elevation areas of the Chapada Diamantina plateaus, state of Bahia, while the other occurs in the cerrados of “Serra Geral”, in the occidental plateaus of that state. Psilops paeminosus comprises three distinct allopatric clades that, based on current evidence, cannot be diagnosed morphologically: one from the vicinities of the type locality, one from the lower São Francisco River, and a third from the uplands of Minas Gerais and southern inland Bahia. We keep the latter two as candidate species but defer their formal description until further evidence allows robust diagnosis. Derived clades of Psilops with shorter limbs have invaded hotter and drier environments, while mostly used sandy soils along their evolution.

Boulengerula spawlsi
Wilkinson, Malonza & Loader, 2017

Abstract

A new species of herpelid caecilian, Boulengerula spawlsi sp. nov., is described based on nine specimens from Ngaia (= Ngaya or Ngaja) Forest Reserve, Nyambene Hills, Meru County, Kenya collected between 2007 and 2013. The new species differs from all other Boulengerula in having more anteriorly positioned tentacular apertures and tentacular grooves that are partly or completely covered by the maxillopalatines. Specimens of the new species were previously erroneously reported as a rediscovery of the poorly known congener Boulengerula denhardti Neiden, 1912 together with a biogeographic scenario to explain their disjunct distribution that is not required.

Abstract

Three species of the xenisthmid genus Xenisthmus Snyder are recorded from the Red Sea. Xenisthmus polyzonatus (Klunzinger), the only described species previously known from the Red Sea, is reported on the basis of eight specimens from Egypt, Eritrea and Saudi Arabia. Xenisthmus oligoporus new species is described from four specimens, 17.7–25.0 mm SL, from Sudan and Saudi Arabia. It is distinguished from all other congeners in having a reduced number of cephalic sensory pores and 14–15 segmented rays in the second dorsal fin. Xenisthmus balius Gill & Randall is newly recorded from the Red Sea on the basis of 13 specimens from Eritrea, Egypt and Saudi Arabia. The new specimens of this species are described and compared with previously known specimens, the holotype and eight paratypes from the Arabian (= Persian) Gulf. All three species are described in detail and illustrated with colour photographs. An identification key to the species is also provided.

Keywords: Pisces, Arabian Gulf, taxonomy, key to species



Xenisthmus oligoporus new species
 Few-pored wriggler

DiagnosisXenisthmus oligoporus is distinguished from congeners in having a reduced number of cephalic sensory pores (lacking pores A, I, J, K, P and Q) and in having 14–15 segmented rays in the second dorsal fin.

Etymology. The specific epithet is from the Greek oligos (few) and poros (hole) and alludes to the relatively low number of sensory pores on the head. To be treated as a noun in apposition.

Habitat and distribution. Known from sandy areas adjacent to reefs in 6–13 m. The species is currently known from Duba, Saudi Arabia, south to the Farasan Archipelago (Figure 3).


Xenisthmus balius Gill & Randall, 1994 
Freckled wriggler

Diagnosis. A species of Xenisthmus with the following combination of characters: dorsal-fin rays VI + I,13 (rarely I,14); anterior rim of posterior nostril raised, without well-developed flap; scales of body mainly cycloid; head and body pale, with reticulate mottling dorsally.

Habitat and distribution. Xenisthmus balius was previously known only from Jana Island, Saudi Arabia, in the Arabian Gulf. We newly record this species from the Red Sea on the basis of 13 specimens collected in Eritrea, Egypt and Saudi Arabia (Figure 3). It has been collected from sandy areas adjacent to coral rubble and reefs in 1.5– 17 m.


Xenisthmus polyzonatus (Klunzinger, 1871) 
Bullseye wriggler

Diagnosis. A species of Xenisthmus with the following combination of characters: second dorsal-fin rays usually I,11 (rarely I,12); anal-fin rays I,10–11; tongue rounded to truncate; and posterior nostril with well-developed anterior flap.

Thismia bryndonii   Tsukaya, Suetsugu & M.Suleiman


Thismia Griffith (1845: 341) in Thismiaceae or Burmanniaceae (sensu APG 2016) consists of more than 60 species (Ridley 1924, Jonker 1948, Stone 1980, van Steenis 1982; Merckx 2008). Many new species in this genus have been discovered, and 12 have been described after 2010 (e.g., Dančak et al. 2013, Nuraliev et al. 2014, 2015, Chantanaorrapint & Sridith 2015, Li & Bi 2013, Hroneš et al. 2015). Considering that the majority of these species were collected only once (Jonker 1948), it is likely that many more undescribed species remain hidden in the forests, particularly in the tropical rain forests of Southeast Asia. Borneo is one of the most biodiverse areas for mycoheterotrophs, and our recent botanical exploration in Borneo revealed many previously undescribed mycoheterotrophic species (e.g., Tsukaya et al. 2011, 2014a,b, 2016, Tsukaya & Okada 2005, 2012a,b,c, 2013a,b, Tsukaya & Hidayat 2016, Tsukaya & Suetsugu 2014). In 2016, we conducted a botanical survey in the Malaiu Basin, Sabah, Borneo, with the permission of the Maliau Basin Management Committee (YS/MBMC/2016/184) and the Sabah Biodiversity Council [access license JKM/MBS.1000-2/2JLD.5(23)]. The Maliau Basin Conservation Area (MBCA) is a huge basin surrounded by sandstone ridges and covers approximately 39,000 ha. Few botanical explorations have previously been conducted in this area. During the survey, we encountered a specimen from the MBCA that apparently belongs to Thismia section Euthismia Schltr. subsect. Odoardoa Schlechter (1921: 31) because it has a free inner perianth, spreading, creeping and vermiform roots, perianth lobes equal in length and size, but it differs from all known species. Here, we describe this new species with a revised key to the species of this genus in Malesia.

Taxonomic Treatment 
Thismia bryndonii Tsukaya, Suetsugu & M.Suleiman, sp. nov. 

Type:— MALAYSIA. Sabah: Maliau Basin Conservation Area, along the Belian Trail, elev. ca. 260 m, 30 Sept 2016, Tsukaya, Suetsugu, & Suleiman TSS-14 (holotype: BORH; isotype: TI, a flower in the spirit collection).

 Thismia bryndonii is similar to T. mullerensis and T. lauriana in having a free perianth lobes equal in size and bifid stigmas, but differs in having two anther appendages and pale-orange streaks on the perianth tube with brown-orange transverse bars inside. Asymmetrical coloration of the perianth lobes is also unique to this species


Distribution:— This species was found in the understory of a dipterocarp forest and is only known from the type locality in the Maliau Basin, Sabah, Borneo. 

 Etymology:— The species name Thismia bryndonii was chosen in honour of our guide in the Maliau Basin Conservation Area, Bryndone Farone Bernard, who first discovered this new species on a botanical expedition.

Fortuny, Gastou, Escuillié, Ranivoharimanana & Steyer, 2017


Abstract
Trematosaurids form a very large and remarkable clade of Triassic tetrapods (Temnospondyli: Stereospondyli) with a worldwide geographical distribution. Compared with specimens from Europe, Australia or North America, they remain relatively scarce in African rocks, where they are mainly known in the Early Triassic of Madagascar and South Africa. Longirostrine trematosaurids were only known from Madagascar, represented by the genus Wantzosaurus. However, we describe herein a new species of the longirostrine trematosaurid AphanerammaAphaneramma gavialimimus sp. nov., from the Olenekian (Lower Triassic) of Madagascar. This genus was previously known from the Early Triassic of Europe and Asia. Based on a new nearly complete skull, the new species is characterized by a premaxilla-nasal suture anteriorly directed, not contacting the nostrils; choanae completely included within the palatines; the ventral opening of the orbits in the anterior part of the interpterygoid vacuities; a very elongated nasal covering more than 50% of the prenarial length; and an anteriorly widened cultriform process. Aphaneramma gavialimimus sp. nov., with a skull length of about 40 cm, may be one of the largest known trematosaurids. Its inclusion in a new phylogenetic analysis confirms its close affinities with the North American genus Cosgriffius, and clarifies the relationships of trematosaurids in general and lonchorhynchines in particular. The new species also increases the palaeobiodiversity of marine trematosaurs in Gondwana and allows discussing their apparently rapid cosmopolitanism just after the great Permian–Triassic mass extinction.

Ooderella smithii Ashmead, 1896


  Abstract

The world species of Ooderella Ashmead, 1896 are revised. Characterization of the genus is based primarily on females, but for the first time males are associated with females through collecting events and described for four species. Putative generic features of males as well as morphological limits of both sexes are discussed, as are possible infrageneric relationships. Previously consisting of a single species from South America, Ooderella smithii Ashmead (♀, ♂), 18 new species are described from the Neotropical, Nearctic and Afrotropical regions, including one from the Nearctic region [O. americana n. sp. (♀)], 5 from the Afrotropical region [O. botswanae n. sp. (♀), O. capensis n. sp. (♀), O. gymnosoma n. sp. (♀), O. kenyaensis n. sp. (♀), and O. platyscapus n. sp. (♀, ♂)], and 12 from the Neotropical region [(O. ambigua n. sp. (♀), O. flavida n. sp. (♀), O. hansoni n. sp. (♀), O. hyalipleura n. sp. (♀), O. melanosceles n. sp. (♀), O. microptera n. sp. (♀), O. reticulifrons n. sp. (♀), O. setosa n. sp. (♀, ♂), O. speculifrons n. sp. (♀), O. spinositegula n. sp. (♀, ♂), O. stenoptera n. sp. (♀), and O. thegalea n. sp. (♀)]. The species are keyed, described, illustrated through macrophotography, and their distributions mapped.

Oligodon culaochamensis 
Nguyen, Nguyen, Nguyen, Phan, Jiang & Murphy, 2017


Abstract

A new kukri snake, Oligodon culaochamensis sp. nov., is described from Cu Lao Cham Islands, central Vietnam, based on the morphology of six specimens, including two males, three females and one juvenile. The new species belongs to the O. cyclurus group and differs from other congeners in this group by a combination of the following characters: medium size in adults (total length up to 582 mm); 17–19 dorsal scale rows at neck and midbody and 15 or 17 rows before vent; tail length/total length ratio 0.218–0.219 in males and 0.166–0.169 in females; ventrals 167–169 in males and 179–182 in females; subcaudals 63–66 in males and 51–52 in females; head scalation complete with a presubocular; 9–10 maxillary teeth, the posterior three being enlarged; nasal divided; temporal streak absent; long and deeply forked hemipenes extending to 20th subcaudal and without spines and papillae but with prominent diagonal ridge, oblique flounces and distal calyces; cloacal plate undivided; 10–11+3–4 dorsal blotches; and a vertebral stripe on tail and anterior part of body. This is the second species of Oligodon described on islands of Vietnam.

Keywords: Reptilia, Quang Nam Province, hemipenis, maxillary teeth, Oligodon chinensisOligodon culaochamensis sp. nov.


Paratype of Oligodon culaochamensis sp. nov., ITBCZ 5631, male. 

Natural history. All specimens were collected .. on the ground in dry primary forests or plantations, usually near the bank of small streams. The stomach of the holotype contained two soft shell eggs (size 15 mm x 7 mm). These eggs probably belong to a snake or lizard.

Distribution. The new species is currently known only from Cu Lao Cham Islands, Quang Nam Province, Vietnam. 

Etymology. The specific epithet culaochamensis is derived from Cu Lao Cham Islands, where the new species was discovered.

Abstract

We describe a new species of toad from the Great Basin region of northern Nevada belonging to the Bufo (Anaxyrus) boreas species complex. This cryptic species was detected through genetic analyses of toad populations sampled throughout the Great Basin and the morphological evidence was quantified through extensive sampling of live toads within the region. The new species has the smallest body size in the species complex, and can be further diagnosed from other species in the complex by its large tibial glands and unique coloration. The known distribution of the new species is restricted to an area less than 6 km2 in Dixie Valley, Churchill Co., Nevada. The Great Basin is an arid region where aquatic resources are both rare and widely scattered, making habitat suitable for anuran populations highly vulnerable to anthropogenic change. The habitat occupied by this newly described species is threatened by the incipient installation of geothermal and solar power development projects that require the water that defines its habitat.

Bufo(Anaxyrus) williamsi sp. nov. 
Dixie Valley Toad

Diagnosis. Bufo (Anaxyrus) williamsi is distinguishable from B. boreas by a combination of diagnostic morphological characters (Fig. 4; Table 1, Table 2), genetic evidence (Fig.3, Fig. 6), and localized distribution (Fig. 2b). Bufo (Anaxyrus) williamsi is distinct from B. boreas by: a small adult body size (SVL is more than 2.5 cm smaller than B. boreas; Table 1); significantly, but modestly, larger, closely-set eyes, and smaller head (Table 2); statistically and perceptibly larger tympanum, and shorter hind limbs; conspicuously large and elevated tibial glands; and distinctive color pattern (Fig. 4a, Fig. 4b).

Etymology. The specific epithet is in tribute to Robert Williams, former Field Supervisor of the U.S. Fish and Wildlife, whose Herculean efforts on behalf of the fauna of Nevada and California were critically important in discovering additional biodiversity of anurans in the Great Basin, and in focusing on the needs to provide protection to the rare and imperiled fauna, and the ecosystems upon which they depend, in Nevada and California. The Dixie Valley toad would not have been discovered without the efforts of this courageous public servant.

Distribution. Bufo (Anaxyrus) williamsi is found only within wetlands of limited extent fed from artesian springs on the western edge of the Dixie Valley Playa, east of the Stillwater Range in Dixie Valley, NV (Fig. 2b).

Natural history.Bufo (Anaxyrus) williamsi is restricted to the spring fed-wetland habitat along the western edge of the Dixie Valley playa. Similar to other toads in the B. boreas complex (except perhaps B. exsul, which is more aquatic), the terrestrial B. williamsi is typically nocturnal, emerging at dusk, and can be found in moist vegetation or in very still, shallow water with very little vegetation canopy. Dixie Valley experiences extreme temperature fluctuations between day and night temperatures, as well as season-to-season extremes, characteristic of cold desert ecosystems.

Platystele baqueroi  Jost & Iturralde 


Abstract
 A new species of Platystele (Pleurothallidinae: Orchidaceae) is described from foothill forest in the province of Carchi in northwestern Ecuador. The species has relatively large flowers for the genus, with long slender sepaline tails. It resembles Platystele caudatisepala, but is distinguished from that species by the partially connate lateral sepals, the convex lip with reflexed tip and margins, the deflexed petals, sometimes with their tips touching behind the flower, the sepals with recurved margins, and the leaves long-petiolate.

Keywords: Carchi, Ecuador, Orchidaceae, Platystele, Pleurothallidinae

Diagnosis. Similar to the widely distributed P. caudatisepala (C. Schweinf.) Garay, but differs in its more long-petiolate leaves, lateral sepals connate for 2 mm and not divergent, petals usually strongly deflexed, with tips that often meet or cross behind the flower, and adaxial surface of lip strongly convex rather than planar.

Eponymy: Named after Luis Baquero, Quito, Ecuador, enthusiastic orchidologist and conservationist who discovered this species.

Rodrigues & Maranhão dos Santos, 2008 

Abstract

 Scriptosaura catimbau, a new genus and species of elongate, fossorial, sand swimming eyelid-less gymnophthalmid lizard is described on the basis of specimens obtained at Fazenda Porto Seguro, municipality of Buíque, State of Pernambuco, in the Caatingas of northeastern Brazil. The type locality is entirely included within the area of the recently created Parque Nacional do Catimbau. The new lizard lacks external forelimbs, has rudimentary styliform hindlimbs and is further characterized by the absence of prefrontal, frontal, frontoparietal and supraocular scales, and by having one pair of chin shields. A member of the Gymnophthalmini radiation, the new genus is considered to be sister to Calyptommatus from which it differs externally by the absence of an ocular scale and absence of an enlarged temporal scale.

FIGURE 3. Living specimen of Scriptosaura catimbau from Parque Nacional do Catimbau. 

Scriptosaura, gen. nov.

Definition: An elongate and short tailed gymnophthalmid lacking an ear opening and eyelid. Forelimbs absent, hindlimbs rudimentary, styliform, ending in a short apical scale; nail absent. Frontonasal single; prefrontals, frontal, frontoparietals, supraoculars, and loreal absent. Parietals longer than wide, contacting frontal. Nostril in the center of nasal. Collar fold absent. One pair of chin shields. Dorsal scales cycloid anteriorly, posteriorly smooth, hexagonal, keeled and slightly mucronate, in regular transverse series; lateral scales enlarged, smooth. Ventral scales smooth, in four regular transverse series, the external ones wider. Males with four preanal pores, absent in females.

Etymology: From the Latin “scriptor” = writer, and “saura” = lizard in reference to the sand tracks left by this sand swimming species. The tracks are in the origin of its popular name (escrivão = public writer) which is also attributed to other similar sand swimming lizards like those of the related genera Calyptommatus and Nothobachia.


Scriptosaura catimbau, sp. nov.

Etymology: A noun in apposition, in reference to the type locality, Parque Nacional do Catimbau.

Barleria mirabilis  I. Darbysh. & Q. Luke


Summary
A new species of Barleria (Acanthaceae), discovered in 2014 on the Uzondo Plateau of West Tanzania, is described and illustrated and its affinities are discussed. This is the first documented tree species in the genus Barleria. Its conservation status is assessed using the categories and criteria of IUCN; it is considered to be globally Vulnerable.

Key Words: conservation, IUCN Red List assessment, Mpanda, taxonomy, Uzondo

RECOGNITION: Barleria mirabilis is most similar to B. crassa C. B. Clarke and B. nyasensis C. B. Clarke but differs markedly from both in being a tree to 4 – 6 m tall at maturity (vs a perennial herb or shrub 0.3 – 2.5 m tall); in having broader, elliptic or oblanceolate bracteoles 3 – 5 mm wide and lacking a spine tip (vs bracteoles linear-lanceolate with a spine tip or reduced to a simple spine, 0.5 – 3 mm wide); in the bracteoles and posterior and anterior calyx lobes having numerous conspicuous capitate “mushroom” glands externally (these absent in B. crassa and B. nyasensis which only have scattered small glandular hairs on the calyx); in the anterior and posterior calyx lobes being more convex and with markedly involute, entire margins (vs calyx lobes with margin not or hardly involute; denticulate to spinulose-dentate or rarely almost entire); and in the anthers being larger (6.3 – 6.6 mm vs 3 – 5 mm long).

DISTRIBUTION: Known only from the Uzondo Plateau of West Tanzania.

ETYMOLOGY: The species epithet “mirabilis” (miraculous, astonishing) refers both to the fact that this is a truly remarkable species, being the only tree Barleria recorded to date, and to the fact that such a striking and locally frequent species has not been found previously despite considerable past botanical exploration at the collecting locality.

Inoue & Kondo, 2016

Abstract
Ammonite shells have complex patterns of suture lines that vary across species. The lines are formed at the intersection of the outer shell wall and the septa. The wavy septa can form if the rear mantle of the ammonite, which functions as the template, has a complex shape. Previous hypotheses assumed that the rear mantle is like a flexible membrane that can be folded by some physical force. The elucidation of the mechanism of septa formation requires that the detailed shape of the septa should be known. We developed a new protocol of X-ray micro-computed tomography (CT) and obtained high-resolution three-dimensional (3D) images of the septa of the Upper Cretaceous ammonite Damesites cf. damesi. The obtained image suggested that the wavy and branched structures of the rear mantle grew autonomously. We found that some extant sea slugs have branched structures and showed similar shape and growth sequence as those in fossils, suggesting that the mantle of molluscs basically has the potential to form branched projections. Based on the characteristics of the obtained 3D structure, we explain how ammonites might have formed the complex suture patterns.

Andinobates victimatus 
Márquez, Mejía-Vargas, Palacios-Rodríguez, Ramírez-Castañeda & Amézquita, 2017

Abstract

Northwestern South America is among the most biodiverse, albeit unexplored, regions of the world. The genus Andinobates is made up of 14 species, all distributed in Northwestern South America (Colombia and Northern Ecuador), and adjacent Panamá. Within the last decade, five species of this genus have been described. In this paper we describe yet another species, belonging to the Andinobates fulguritus group, from the Urabá region of Northwestern Colombia. The new species can be distinguished from other members of Andinobates on the basis of a unique combination of coloration, size, and advertisement call parameters. Molecular phylogenetic and genetic distance analyses corroborate the species’ taxonomic affinity, and further support its status as a distinct lineage. Finally, we discuss the implications of our findings on the systematics of the A. fulguritus group.

Andinobates victimatus sp. nov.

Etymology. From the Latin victimatus  (the victimized); noun in apposition. The Urabá region, where this species occurs, has historically been flailed by Colombia’s longstanding armed conflicts, perhaps more than most other regions of the country, leaving a virtually countless trail of innocent victims. We name this species in honor and remembrance of all these victims.

Astyliasula phyllopus  (De Haan, 1842) 

Schwarz & Shcherbakov, 2017   

Abstract

The Bornean Oxypilinae species previously included in the genus HestiasulaSaussure, 1871 are revised. External morphology and genital characters of Sundaian taxa differ considerably from the Indian type species H. brunnerianaSaussure, 1871, necessitating taxonomic and nomenclatural changes. The genus Catestiasula Giglio-Tos, 1915 is reinstated. It is characterized by the apomorphic partial fusion of the dorsal and ventral laminae of the left phallomere, and by the complete reduction of the apical process. It is represented on Borneo with two species, C. nitida (Brunner de Wattenwyl, 1893) and C. moultoniGiglio-Tos, 1915. An additional species, C. seminigra(Zhang, 1992)n. comb. occurs in continental SE Asia. Two new genera are described, united by the lack of styli, the presence of dorsal carinae on the subgenital plate, and the unique morphology of the dorsal lamina of the left phallomere, but differing in the morphology of head and forelegs. Astyliasula gen. nov. accommodates A. phyllopus (De Haan, 1842) n. comb. and related species from the Sunda Islands and continental SE Asia: A. basinigra (Zhang, 1992)n. comb., A. hoffmanni (Tinkham, 1937) n. comb., A. javana (Beier, 1929) n. comb., A. major (Beier, 1929) n. comb., A. inermis(Wood-Mason, 1879) n. comb., and A. wuyshana (Yang & Wang, 1999) n. comb.. Hestias sarawaca Westwood, 1889 is removed from synonymy with A. phyllopus and reinstated as Astyliasula sarawaca(Westwood, 1889)n. comb.. The monotypic taxon Pseudohestiasula borneana gen. nov. sp. nov. is erected for a Bornean endemic more closely related to Astyliasula than to the other genera. Hestiasula is now restricted to H. brunneriana and related species from India and adjacent countries. The tribe Hestiasulini Giglio-Tos, 1915stat. rev. is proposed for all genera more closely related to Hestiasula than to other Oxypilinae, that is Hestiasula, Ephestiasula, Catestiasula, Astyliasula, and Pseudohestiasula. New data on the ecology and distribution of all Bornean Hestiasulini as well as a key to the Oxypilinae of Borneo are provided.

 Artwork by Sean Murtha @KsepkaLab  DOI: 10.1073/pnas.1700188114 

Significance: 
Molecular (DNA) studies suggest that birds radiated rapidly in the wake of the Cretaceous–Paleogene mass extinction (66 Ma), diversifying into nearly all the major groups we recognize today. However, fossil evidence for this pattern has been difficult to find because of the poor fossilization potential of small, delicate-boned birds. We report a tiny species of bird from ∼62.5 million-year-old rocks in New Mexico. Tsidiiyazhi abini (Navajo for “little morning bird”) is an ancient species of mousebird (Coliiformes). The fossil provides evidence that many groups of birds arose just a few million years after the mass extinction and had already begun evolving specializations of the foot for different ecological roles.

Abstract
Evidence is accumulating for a rapid diversification of birds following the K–Pg extinction. Recent molecular divergence dating studies suggest that birds radiated explosively during the first few million years of the Paleocene; however, fossils from this interval remain poorly represented, hindering our understanding of morphological and ecological specialization in early neoavian birds. Here we report a small fossil bird from the Nacimiento Formation of New Mexico, constrained to 62.221–62.517 Ma. This partial skeleton represents the oldest arboreal crown group bird known. Phylogenetic analyses recovered Tsidiiyazhi abini gen. et sp. nov. as a member of the Sandcoleidae, an extinct basal clade of stem mousebirds (Coliiformes). The discovery of Tsidiiyazhi pushes the minimum divergence ages of as many as nine additional major neoavian lineages into the earliest Paleocene, compressing the duration of the proposed explosive post–K–Pg radiation of modern birds into a very narrow temporal window parallel to that suggested for placental mammals. Simultaneously, Tsidiiyazhi provides evidence for the rapid morphological (and likely ecological) diversification of crown birds. Features of the foot indicate semizygodactyly (the ability to facultatively reverse the fourth pedal digit), and the arcuate arrangement of the pedal trochleae bears a striking resemblance to the conformation in owls (Strigiformes). Inclusion of fossil taxa and branch length estimates impacts ancestral state reconstructions, revealing support for the independent evolution of semizygodactyly in Coliiformes, Leptosomiformes, and Strigiformes, none of which is closely related to extant clades exhibiting full zygodactyly.

Tsidiiyazhi abini, gen. et sp. nov

Etymology. The genus and species names are derived from the Navajo (Diné Bizaad) language, reflecting the discovery of the fossil within ancestral Navajo lands. The genus name is derived from the words “tsidii” for “bird” and “yazhi” for “little,” in reference to the fossil’s small size. The specific epithet is derived from the Navajo word “abini” for “morning,” referencing the early Paleocene age of the taxon. Pronunciation using International Phonetic Alphabet phonetic symbols is as follows: /tsɪdi:jæʒi:/ /′ɔbɪnɪ/.

Type Locality and Horizon. NMMNH locality L-6898 comprises a relatively thin (<10 cm) muddy siltstone bed of restricted areal extent, representing an exposure of the Ojo Encino Member of the Nacimiento Formation. The site is located on the West Flank of Torreon Wash within the San Juan Basin, in Sandoval County, New Mexico. ....

Diagnosis. Tsidiiyazhi abini is differentiated from all other Coliiformes by the following apomorphies: (i) tubercle on the medial face of cranial end of the scapula, (ii) strongly developed triangular protuberance at the apex of impressio m. sternocoracoidei of the coracoid, (iii) medially displaced distal exit of canalis extensorius of the tibiotarsus, and (iv) arcuate arrangement of the metatarsal trochleae.

Abstract

A characteristic new species Meotipa sahyadri n. sp. with tall and white translucent abdomen in females is described in detail based on morphology of both sexes, based on specimens collected from the Western Ghats of Maharashtra, Gujarat and Goa. The new species has epigynal projection which is known only in Meotipa picturata Simon, 1895, but differs in shape (trifid vs. quadrangular respectively). Males have longest straight embolus exceeding conductor length. Observations of its natural history are provided. Meotipa picturata is newly recorded from Goa, which extends its north-westward distribution from the previously known records from ‘Kodei Kanal’, India (type locality), Ratchasima Province, Thailand and East Kalimantan, Indonesia. A new combinationMeotipa andamanensis (Tikader, 1977) n. comb. (=Argyrodes andamanensis) is proposed based on the comparison of description and illustrations provided in the original paper to that of the characters of the type species M. picturata. 242 morphological characters studied in the previous literature and one additional character ‘epigynal projection’ were scored for Meotipa sahyadri n. sp. and Meotipa picturata. These species were obtained monophyletic, placed within Theridiinae as sister to Chrysso cf. nigriceps using parsimony analysis and Bayesian inference.
