A New Species

A new species of genus Megophrys from Gaoligong Mountains, Yunnan Province, China is described. Phylogenetic analyses based on mitochondrial DNA and nuclear DNA all clustered the new species as an independent clade nested into the subgenus Panophrys. The smallest genetic distance based on 16S rRNA gene between the new species and its congeners was 3.0%. The new species could be identified from its congeners by a combination of following characters: moderate body size (SVL 31.0–34.8 mm in males); vomerine ridge weak, vomerine teeth absent; dorsal skin relatively smooth; tongue slightly notched behind; tympanum rounded and relatively large, 0.54 times of eye length; a horn-like tubercle on edge of each upper eyelid small; tibio-tarsal articulation reaches middle eye when leg stretched forward; finger tips rounded, not expanded to small pad; toes with narrow fringes and rudimentary webbing; ventral hindlimbs semitransparent purplish with greyish white pigments; ventral body scattered with distinct dark patches in the middle.

A New Species

The genusOdorranais widely distributed in the mountains of East and Southeastern Asia. An increasing number of new species in the genus have been recognized especially in the last decade. Phylogenetic studies of theO. schmackerispecies complex with wide distributional range also revealed several cryptic species. Here, we describe a new species in the species complex from Guizhou Province of China. Phylogenetic analyses based on mitochondrial DNA indicated the new species as a monophyly clustered into theOdorranaclade and sister toO. schmackeri, and nuclear DNA also indicated it as an independent lineage separated from its related species. Morphologically, the new species can be distinguished from its congeners based on a combination of the following characters: (1) having smaller body size in males (snout-vent length (SVL) <43.3 mm); (2) head longer than wide; (3) dorsolateral folds absent; (4) tympanum of males large and distinct, tympanum diameter twice as long as width of distal phalanx of finger III; (5) two metacarpal tubercles; (6) relative finger lengths: II < I < IV < III; (7) tibiotarsal articulation reaching to the level between eye to nostril when leg stretched forward; (8) disks on digits with circum-marginal grooves; (9) toes fully webbed to disks; (10) the first subarticular tubercle on fingers weak; (11) having white pectoral spinules, paired subgular vocal sacs located at corners of throat, light yellow nuptial pad on the first finger in males.

A New Species

Species of the genus Garra from the Irrawaddy and Salween River basins in west Yunnan, China are difficult to identify and their taxonomy remains problematic. We conducted a systematic review of the genus using a combination of molecular and morphological approaches to address these issues and describe a new species, G. surgifrons. Phylogenetic analyses indicate that 15 species of Garra do not form a monophyletic group. Garra imberba and G. nujiangensis form a distinct clade that is not sister to the remaining species of Garra. According to the combination of morphological characters of the proboscis and rostrum, Garra from western Yunnan Province can be divided into 4 groups: (1) smooth snout; (2) unilobed proboscis; (3) bi-lobed proboscis; and (4) tri-lobed proboscis. The types of snout shapes in Garra are consistent with the topological structure of the phylogenetic tree. Garra surgifrons can be distinguished from all other congeners occurring in China and Southeast Asia by a combination of the following characters: presence of a transverse lobe and a tri-lobed proboscis; both dorsal and caudal fins without black markings; the proboscis short and broad, a roughly quadrate shape from the dorsal view with a poorly developed and slightly protuberant middle lobe, with the front tip not suspended from the lateral view and the width almost equal to the width of the lateral lobes; the posterior margin of mental adhesive disc extending close to or reaching the vertical through the central line of the eye and never reaching the posterior margin of the eye; two pairs of barbels; 16 circumpeduncular scales; and 32–34 lateral line scales.

Hoya pyrifolia, a new species of Apocynaceae from Yunnan Province, China, is described and illustrated. Results from phylogenetic analyses, based on combined DNA fragments of the nuclear ribosomal external transcribed spacer (ETS), intergeneric transcribed spacer (ITS) and three plastid DNA fragments (matK, psbA-trnH and trnT-trnL), showed that the new species was nested within a clade, including Hoya species distributed in the subtropical foothills of the Himalayas and the Tibet-Sichuan Plateau. Morphologically, the new species can be distinguished from its close relatives by its pyriform and slightly pubescent leaves, as well as the 4-flowered inflorescences.

The Asian music frog genus Nidirana is widely distributed in East and Southeastern Asia. Systematic profiles of the group remain on debate, and cryptic species are expected especially in the species with wide distributional range. Here, we describe a new species of the genus from Southwestern China. Phylogenetic analyses based on mitochondrial DNA and nuclear DNA supported the new species as an independent clade nested into the Nidirana clade and sister to N. hainanensis. Morphologically, the new species could be distinguished from its congeners by a combination of the following characters: a large body size in males (SVL > 49 mm); the presence of lateroventral grooves both on fingers and toes; relative finger lengths: II < IV < I < III; tibiotarsal articulation reaching the level between eye and nostril when leg stretched forward; a pair of subgular internal vocal sacs at corners of throat in males; nuptial pad present on the inner side of base of fingers I and II in males in breading season; webbing formula: I 2 –21/3 II 2 –22/3 III 31/2 –32/3 IV 32/3 –3V. The findings provided a better knowledge on phylogenetic assignments of the genus Nidirana, and indicated future deeper investigations necessarily for exploring systematic settings of the group.

Summary A new species of entomopathogenic nematode, Steinernema borjomiense n. sp., was isolated from the body of the host insect, Oryctes nasicornis (Coleoptera: Scarabaeidae), in Georgia, in the territory of Borjomi-Kharagauli. Morphological characters indicate that the new species is closely related to species of the feltiae-group. The infective juveniles are characterised by the following morphological characters: body length of 879 (777-989) μm, distance between the head and excretory pore = 72 (62-80) μm, pharynx length = 132 (122-142) μm, tail length = 70 (60-80) μm, ratio a = 26.3 (23.0-29.3), H% = 45 (40-51), D% = 54 (47-59), E% = 102 (95-115), and lateral fields consisting of seven ridges (eight incisures) at mid-body. Steinernema borjomiense n. sp. was molecularly characterised by sequencing three ribosomal regions (the ITS, the D2-D3 expansion domains and the 18S rRNA gene) and the mitochondrial COI gene. Phylogenetic analyses revealed that S. borjomiense n. sp. differs from all other known species of Steinernema and is a member of the monticolum-group.

A New Species

In northern South America, amphisbaenians are rarely seen among the herpetofauna.Thus, general knowledge about them is very poor. During a herpetological survey in 2012 at Casanare, Colombia, we found two specimens of an unusual Amphisbaena. A third specimen sharing the same morphotype labeled Amphisbaena sp. from Vichada department was found deposided in an Colombian reptile collection. Based on morphological analyses together with phylogenetic analyses of 1029 base pairs of the mitochondrial DNA (mtDNA), we describe a new species of Amphisbaena that inhabits in the Orinoquian region of Colombia. The new species is part of a phylogenetic clade together with A. mertensii and A. cunhai (central-southern Brazil), exhibiting a great genetic distance (26.1–28.9%) between the newly identified lineage versus those taxa, and versus the sympatric taxa A. alba and A. fuliginosa. Morphologically, this new Amphisbaena can be distinguished from their congeners by characters combination of number of preocloacal pores, absence of malar scale, postgenial scales and body and caudal annuli counts. Amphisbaena gracilis is on morphology grounds the most similar species. However, the new species can be distinguished from it by having higher body annuli counts, angulus ories aliegned with the edges of the ocular scales and center of frontal scales, less number of large middorsal segments of the first and second body annulus, and rostral scale visible from above. The description of this new Amphisbaena species points out the urgent need to increase the knowledge of worm lizards in Colombia
