Abstract

Eulophia myanmarica, a species new to science is herein described from Monywa District, Sagaing Region, Myanmar. The species superficially resembles E. andamanensis but differs significantly in having 5-veined petals and sepals, narrowly oblong dorsal sepal with acute, slightly cucullate apex, obliquely narrowly oblong-elliptic lateral sepals and obliquely triangular sidelobes of the labellum. Detailed morphological description, a colour plate, notes on phenology, distribution, and a provisional conservation assessment are provided below. With this discovery, Myanmar now holds a total number of 19 Eulophia species. Additionally, after merging the genus Geodorum under Eulophia, a new name is needed for Geodorum densiflorum, for which taxonomic notes have been provided.

Abstract

Sri Lanka has a rich snake diversity, but the island’s scolecophidians (‘blindsnakes’) are poorly understood due to the cryptic, burrowing habits of these inconspicuous animals and lack of systematic field surveys and morphological and molecular analyses. Here we report findings from a systematic survey carried out over a decade across the island of Sri Lanka, focusing particularly on the globally widespread, parthenogenetic species Indotyphlops braminus. We report 780 locations across the island in which this species was recorded, at elevations of 1–1,424 m asl, and mostly <1,000 m (771 out of 780 localities). We provide a molecular-systematics perspective by reporting new DNA sequence data for 15 specimens from Sri Lanka, and new analyses of asiatyphlopine molecular genetic diversity and relationships. Based on molecular results, we conclude that (i) Indotyphlops, as originally conceived may not be monophyletic, (ii) phenotypically the I. braminus-like blindsnakes widespread across most of Sri Lanka are a single, genetically homogeneous species, and (iii) some populations from peninsular India are very similar in DNA sequence to I. braminus from Sri Lanka, but others are genetically highly distinct and unlikely to be conspecific. Based on the estimated phylogenetic relationships, we recommend that I. braminus is currently best recognized as a phenotypically exceptional species of Indotyphlops rather than, as recently proposed, the only species of a monotypic genus (Virgotyphlops).

Phelsuma dorsivittata paradoxa

Abstract

We describe a new subspecies of day gecko, Phelsuma dorsivittata paradoxa ssp. n. (Squamata: Gekkonidae) from Nosy Be Island and the Sambirano region in northwestern Madagascar. Due to its colouration and small size, Phelsuma d. paradoxa shares at first glance more similarities with P. parva or P. quadriocellata than with P. d. dorsivittata. Yet, phylogenetic analysis of mitochondrial and nuclear-encoded DNA sequences unambiguously shows that P. d. paradoxa is related to the allopatrically distributed P. d. dorsivittata. Due to the substantial and constant morphological divergence and the geographic separation between the two taxa we concluded that assigning them an initial status of subspecies is adequate, although they are not reciprocally monophyletic in mitochondrial DNA. Subsequently we discuss possible scenarios for eyespot convergence and mitochondrial paraphyly within P. dorsivittata. Furthermore, the molecular data presented here confirm the separate position of P. lineata punctulata within the P.dorsivittata complex. In order to resolve the paraphyly of the Phelsuma lineata complex, we here elevate this taxon to species rank, as Phelsuma punctulata Mertens, 1970.

Phelsuma dorsivittata paradoxa ssp. n.

Diagnosis. Phelsuma dorsivittata paradoxa is a member of the Phelsuma lineata species group and characterized by small size, green dorsal colour in life with red markings and a relatively large black posthumeral spot that is dorsally surrounded by light blue colour. It differs from all other species in the genus Phelsuma (except P. quadriocellata andP. parva) by the presence of an oval blackish spot behind the insertion of forelimbs (posthumeral spots), which is dorsally bordered by a light blue ring that does not extend onto the back. It furthermore differs from most other species in the lineata group (P. antanosy, P. comorensis, P. dorsivittata, P. lineata, P. punctulata, and P. quadriocellata) by smaller size (max. TL ≤ 92 mm versus ≥ 110 mm; max. SVL ≤ 44 mm versus ≥ 46 mm). P. d. paradoxa differs from the most similar species P. parva by the presence of a distinct dark prefemoral spot, by less distinct whorls on the tail (compare Fig. 6), and by the pattern of mental scales, which are continuously and gradually decreasing in size in P. d. paradoxa (versus irregularly decreasing in P. parva). It differs from P. quadriocellata by smaller size (max. TL 92 mm; max. SVL 44 mm versus max. TL 110 mm, max. SVL 63 mm) and usually by larger red markings on the back. P. d. paradoxa differs from other Phelsuma species by a distinct genetic distance in mitochondrial and nuclear genes.

Phelsuma dorsivittata paradoxa differs from individuals assigned to the nominal subspecies, P.dorsivittata dorsivittata, by distinctly smaller size (max. TL 92 mm / max. SVL 44 mm versus max. TL 130 mm / max. SVL 57 mm), presence of blue colour around the posthumeral spot (versus absent), a slightly lower number of preanofemoral pores in males (21–27 versus 25–29), slightly fewer subdigital lamellae under the fourth toe (13–16 versus 16–19), and higher number of interorbitalia (25–29 versus 24–25). Most of these differences also apply to the male holotype of P. dorsivittata (SMF 59373) with the following data (according to Mertens 1964 and Rocha et al. 2010: 21, respectively): 57 / 55.3 mm SVL, 130 / 124.9 mm TL, no blue ring around posthumeral spot, 27 / 28 preanofemoral pores, 18 subdigital lamellae under the fourth toe, number of interorbitalia not available.

Etymology. The subspecies epithet ‘paradoxa’ is the feminine form of the Latin adjective paradoxus (derived from Greek παράδοξος—parádoxos) meaning “contrary to expectation” but also “marvellous”. This name was given in reference to the fact that these day geckos appear very similar to P. quadriocellata and P. parva at first sight, but contrary to this expectation they are actually closely related to the northern P. dorsivittata clade.

ABSTRACT

A new species of Loxosceles of the laeta species-group, L. vicentei sp. nov., found in Chile is described and illustrated. The male of this species can be distinguished from that of other species by having a long and straight embolus with a truncated tip. The female is distinguished by the spermatheca with a large base and two slender, curved receptacles in both sides.

Loxosceles vicentei sp. nov.

Diagnosis. Loxosceles vicentei sp. nov. can be confused in Chile only with L. coquimbo, but can be distinguished by the presence of dark-brown spots on carapace (Figs. 1A-B). The male resembles L. coquimbo by its palp with a globose bulb, but differs by having a long embolus, straight with a truncated tip (Figs. 2 A-C), while in L. coquimbo the embolus is short and sinuous at tip; in other species of laeta species-group such as L. laeta and L. surca Gertsch, 1967 the embolus is slender and curved. In L. vicentei sp. nov. the male palpal tibia is shorter (1.5 long, 0.6 wide) (Figs. 2 A-B) than in L. coquimbo (2.1 long, 0.5 wide). The females can be distinguished from other Chilean species by the spermatheca with large base and two slender, curved receptacles in both sides. The seminal receptacles of females of L. vicentei sp. nov. and L. coquimbo are similar, however in the new species the distance between the base of the receptacles is larger (1.3 times) than in L. coquimbo (Fig. 2D).

Etymology. The specific name is a patronymic for Vicente Villablanca, son of Javier Villablanca and the collector of the type material.

Urocotyledon norzilensis

DOI: 10.11646/zootaxa.5150.4.4

twitter.com/NancyBunbury

Abstract

Urocotyledon inexpectata, a small gecko endemic to the granitic islands of the Seychelles, has previously been demonstrated to comprise two highly distinct clades based on mitochondrial and nuclear DNA sequences, with one lineage exclusive to a northern group of islands, and the second lineage exclusive to the more southerly islands. Here we complement the genetic data with additional analyses to determine if the clades should be considered distinct species. We present and analyse new morphological data, including skull and jaw osteology, and supplement the available genetic data with DNA sequences for individuals from the previously unsampled island of Felicité, which cluster with the other northern island samples. Despite the high morphological similarity between Urocotyledon populations from northern and southern islands, diagnostic characters were identified, with the northern lineage having a more completely ossified skull, more tooth loci on maxilla and dentary, shorter hindlimbs, relatively smaller eye diameter and relatively wider head. We therefore describe the northern lineage as a distinct species, Urocotyledon norzilensis sp. nov., and discuss the biological and conservation management implications of this taxonomic action.

Urocotyledon norzilensis sp. nov.

Etymology. The name “norzilensis” derives from two local words, “nor” and “zil” which in Seselwa, the official Seychelles creole language, refer to “north” and “islands”, respectively, and refer to the geographical distribution of this cryptic species. The termination “-ensis” refers to being from a place or locality.

Tylototriton houi & Echinotriton raffaellii

DOI: 10.1093/zoolinnean/zlac038

twitter.com/ChrisDufresnes

Abstract

Crocodile newts (Echinotriton and Tylototriton) are emblematic of the biodiversity of South-East Asia. In this study, we provide an account of their evolution, diversity and phylogeography based on mitochondrial (16.2 kb) and nuclear sequences (3.2 kb), combining barcoding data from nearly 1200 specimens collected over ~180 localities, representative of all lineages known to date. While phylogenies of nuclear data lacked resolution, the mitochondrial tree showed dynamic allopatric speciation that followed climate cooling during the last 10 million years, a pattern shared with many other tropical and subtropical amphibians. In crocodile newts, this implies weak dispersal and local adaptation as contributing factors of isolation, and was accompanied by macro- and micro-evolutionary changes in reproductive behaviours. Specifically, our resolved phylogeny of Tylototriton allowed the tracing of a major shift from conserved habits of terrestrial clutch-spawning towards more plastic strategies involving both aquatic and land spawning of single eggs. Using this framework, we then revised the taxonomy of crocodile newts by describing a new subgenus and two new species. Our study provides a basis to guide future phylogeographic, speciation and conservation research on these iconic amphibians.

新宁羽叶报春 || DOI: 10.3897/phytokeys.199.85231

Abstract

Primula xinningensis Wei Zhang bis & J.W.Shao, a new species from Hunan Province, China, is described. Its leaf morphology is similar to the P. merrilliana complex and flower morphology similar to P. cicutariifolia, but it can be distinguished from the former by the black pollen sac, corolla lobes apex obviously emarginate and can be differed from the latter by cotyledon triangular obovate, plants densely covered with glandular hairs and special habitat (karst caves). The whole plastid genome of this new species is 151, 601–151, 630 bp in length. Based on the whole plastid genome sequences, phylogenetic trees revealed that the new species did not genetically relate to the above two mentioned morphologically similar species, but it was closely related to P. hubeiensis. Currently, only three populations were discovered within a small distribution area, thus, it is preliminarily considered as Vulnerable (VU) according to criteria of the IUCN Red List.

Lycodon ankardaya

Lycodon truongi

Nguyen, Duong, Wood & Grismer, 2022.

DOI: 10.3897/vz.72.e82201

Abstract

An integrative taxonomic analysis of species in the colubrid genus Lycodon Fitzinger, 1826 recovered two new syntopic species of the L. rufozonatus complex from the imperiled Song Giang River valley in Khan Hoa Province, of Southern Vietnam. Although L. truongi sp. nov. and L. anakradaya sp. nov. are syntopic, they are not particularly closely related and can be differentiated from each other and all other species in the L. rufozonatus complex on the basis of meristics, morphometrics, color pattern, and uncorrected pairwise genetic distance based on the mitochondrial gene cytochrome b. The discovery of these two new range-restricted species and a previously described range-restricted gekkonid in the genus Cyrtodactylus Gray, 1828 from the same valley, underscores the necessity of continued field work in the Song Giang River valley so as to catalog the unrealized herpetological diversity in this area and establish research-based conservation programs.

Abstract

Caridina stellata sp. nov. is described from streams in Guangxi, south-western China. The new species clearly belongs to “Caridina serrata group” of the genus and shows a morphological similarity with C. cantonensis Yu, 1938, C. serrata Stimpson, 1860 and C. pacbo Do et al. 2020. Caridina stellata is distinguished from congeners, based on differences in its male first pleopod and appendix masculina morphology, along with COI and 16S rRNA molecular evidence. The first pleopod endopod in male is rectangle, about 0.70 × length of exopod, about 3.7–3.9 × as long as proximally wide, inner margin concave, bearing nearly equal spine setae, outer margin bearing nearly equal long and dense spine setae; appendix interna well developed, arising from distal 1/5 of endopod, reaching to end of endopod, with cincinuli distally. The new species displays a unique and brightly coloured pattern and, therefore, can be easily recognised in the field. Liang & Zhou, 1993 described C. cavernicola from the Lenggu Cave, Du’an County, Guangxi. However, the description was based exclusively on two females. We have collected specimens of both sexes near the type locality and describe herein the previously unknown male and present morphological data on females. Data on the habitat, ecology and levels of threat of the two species are provided and suggest that they should be categorised as vulnerable (VU) under the current IUCN Criteria.

Abstract

Luciogobius punctilineatus n. sp. is described on the basis of 21 type specimens from Kyushu, and the Koshiki and Osumi Islands, southern Japan. It is also found in Kochi Prefecture (Shikoku) and Amami-oshima island (Ryukyu Islands), Japan, confirmed by examination of non-type specimens. The genus Luciogobius includes 15 valid and several undescribed species, and most of them inhabit interstitial spaces of stones and gravel in the intertidal zone. The new species is characterized by the following combination of characters: total second dorsal-fin rays 10–12 (modally 11); total anal-fin rays 12–14 (13); pectoral-fin rays 8–12 (10); vertebrae 16–18 + 22–24 = 39–42 (17 + 23 = 40); pectoral-fin posterior margin slightly concave; pelvic fins united, forming a ventral disc; snout relatively short, length 3.1–4.3% of SL; anus to anal-fin origin (AAA) distance twice body depth at anus, 11.4–16.9% of SL; snout length less than 34.7% of AAA distance; pre-anus length less than 85.5% of pre-anal-fin length; single poorly defined black longitudinal line along mid-lateral body region from behind pectoral fin to caudal-fin base, indistinct anteriorly (line embedded, visible through semi-transparent muscle tissue in fresh or live specimens); black spots forming a single longitudinal row on mid-lateral body surface from behind pectoral fin to caudal-fin base (more distinct in preserved specimens).

Lamarckdromia beagle

McLay & Hosie, 2022

DOI: 10.11646/zootaxa.5129.3.1

Researchgate.net/publication/360243839

Abstract

The Dromiidae of Western Australia are summarized primarily based on specimens from the collection of the Western Australian Museum and some additional material from the Australian Museum, Sydney. The genus Alainodromia McLay 1998, is recorded from Camden Sound, Australia, as a new species Alainodromia dambimangari sp. nov. New evidence suggests that the species of Alainodromia are very likely shell carriers that also have direct development. Five species of Cryptodromia are reported from Western Australia and a new genus, Baccadromia gen. nov., is erected for Dromia (Cryptodromia) bullifera Alcock, 1900. The genus Lamarckdromia Guinot & Tavares, 2003 is revised and now includes three species: L. beagle sp. nov., L. excavata (Stimpson, 1858) and L. globosa (Lamarck, 1818). Six species of Dromiidae are new to Australia: Baccadromia bullifera (Alcock, 1900), Cryptodromia amboinensis (De Man, 1888), C. pileifera Alcock, 1901, Epigodromia rotunda McLay, 1993, and Foredromia rostrata McLay, 2002. New records for Western Australia include: Cryptodromia hilgendorfi De Man, 1888, Epigodromia areolata (Ihle, 1913) and Lewindromia unidentata (Rüppell, 1830). A total of 31 species of dromiid crabs are now known from Western Australian coast with five species endemic to the state. There are more than 40 species of Dromiidae known from Australia of which about 40% are endemic.

Tartarocyon cazanavei

DOI: 10.7717/peerj.13457

Abstract

Serravallian terrestrial vertebrates are very uncommon in the northern margin of the Pyrenean Mountains. A mandible of a new large sized amphicyonid (ca. 200 kg) is here described from the marine deposits of Sallepisse (12.8–12.0 Mya). Despite that this new taxon is close in size to some European amphicyonids from the Miocene (e.g., Amphicyon, Megamphicyon, and Magericyon), the unique morphology of its p4, unknown in this clade, allows the erection of the new genus Tartarocyon cazanavei nov. gen. & sp. This taxon may be derived from a Cynelos-type amphicyonine. The description of this new taxon highlights the erosion of the ecological and morphological diversity of the Amphicyonidae in response to well-known Miocene events (i.e., Proboscidean Datum Event, Middle Miocene Climatic Transition, Vallesian Crisis).

Holotype (MHNBx 2020.20.1) of Tartarocyon cazanavei nov. gen. et sp. from Sallespisse (MN7/8, Southwest France), in occlusal, lingual, and labial views.

Scale bar is 5 cm.

Reconstruction of Tartarocyon cazanavei nov. gen. et sp. feeding on a stranded dolphin along the Serravallian sea.
We know only few on the inland environmental conditions where Tartarocyon lived. This illustration thus combines all the data from the site la Crousquillière in Sallespisse including the intertidal dark deposits, the abundance of the molluscs, and the mandible of Tartarocyon in the high-tide line.

Suborder CANIFORMIA Kretzoi, 1943

Family Amphicyonidae Trouessart, 1885

Tribe Amphicyonini Trouessart, 1885

Genus Tartarocyon nov. gen.

Etymology. Tartaro is the name of a legendary man-eater giant living in the Southwestern French Pyrenees, including the Bearn where the fossil has first been described.–cyon is the Greek for dog.

Tartarocyon cazanavei nov. gen. et sp.

Etymology. Dedicated to Mr Alain Cazanave, owner of the locality, who helped with the excavation during many years.

Diagnosis. Large size Amphicyoninae possessing a complete dental formula. The taxon is characterized by the following features: long diastemata between the premolars, low p2 and p3, absent anterior accessory cuspid on p4, large and individualized distal accessory cuspid on p4, and unreduced m2 and m3. The taxon differs from all the European amphicyonids from the Miocene by the individualization of the distal accessory cuspid from the main cuspid on p4 and the extreme reduction of the distal shelf and cingulid.

Conclusions:

Tartarocyon cazanavei nov. gen. & sp. is a new large amphicyonid from the French locality Sallespisse (12.8–12.0 Ma, France). The specimen may represent a new genus that will be further confirmed or not by future finds. It clearly differs morphologically from the Thaumastocyoninae and Haplocyoninae. It seems that this amphicyonid is a part of the radiation of a group of amphicyonines during the Miocene after MN3 (as exemplified by the genera Pseudocyon, Cynelos, Amphicyon, and Magericyon); it probably derived from a Cynelos-type amphicyonine.

Tartarocyon nov. gen. illustrates the diversity of the amphicyonids in Europe: during MN7/8 amphicyonids were diversified in both the body mass and diet. However, the ecological and diversity reduction of the Amphicyonidae is polyphased. A new comprehensive analysis of the taxonomic and ecologic diversity of the amphicyonids is necessary to better understand the impact of biotic and abiotic factors on the evolution of these predators.

ABSTRACT

A new species, Hornstedtia olivacea Docot & Pranada, from the province of Quezon, Philippines is described here with information on its distribution, habitat and phenology, along with a provisional IUCN conservation assessment. A second-step lectotypification of Hornstedtia conoidea Ridl. is proposed and a previous lectotypification of Hornstedtia microcheila Ridl. is clarified. Examination of the collection Ramos & Edaño 44454 supports the occurrence of Hornstedtia havilandii (K.Schum.) K.Schum. in the Philippines but new material is needed to check if the populations in the province of Sulu are distinct enough from the populations in Borneo to be recognised as a distinct taxon. An updated key to the Hornstedtia species of the Philippines is also provided.

Glischropus meghalayanus

Saikia, Ruedi & Csorba, 2022

DOI: 10.11646/zootaxa.5154.3.8

Abstract

Thick-thumbed bats of the genus Glischropus are currently composed of four recognized species from Southeast Asia, two of which were described in recent times. Among these species, G. aquilus is endemic to Sumatra, G. javanus is restricted to western Java, whereas G. bucephalus is widely distributed north to the Isthmus of Kra and G. tylopus is widespread south to this zoogeographic boundary. Two recently collected Glischropus specimens from Meghalaya state in north-eastern India extend the known distribution range of the genus westward into South Asia by ca. 1000 km. Morphological examination of these specimens and comparison with all known species in this genus revealed marked differences in colouration, dental characters and bacular traits. We therefore describe the Meghalaya specimens as a new species. The discovery of the new species from a forest patch adjacent to Nongkhyllem Wildlife Sanctuary from where another specialized bamboo-dwelling species (Eudiscopus denticulus) was reported recently also underscore the importance of the area from a conservation point of view.

Abstract

Primulina nana C.Xiong, W.C.Chou & F.Wen, a new species of Gesneriaceae from limestone areas of Guangxi, China, is described and illustrated here. It morphologically resembles P. yangshuoensis Y.G.Wei & F.Wen in papillose leaf surface, but can be easily distinguished from the latter by noting a combination of characteristics, especially in its leaf blades, leaf blade indumentum characteristic, calyx lobes, corolla and the disc. We found only one population at the type locality, about 200 mature individuals. According to the IUCN Red List Categories and Criteria (Version 3.1), the new species is provisionally assessed as Critically Endangered (CR).
