Project description:A new species of Acanthosaura from Yunnan, China is described based on unique morphometric and meristic external characters and a very distinctive color pattern. The fourteenth species recorded of this genus, Acanthosaura tongbiguanensis sp. nov., was previously considered A. lepidogaster although it more closely resembles A. crucigera. It can be separated from all other species of the genus by having different numbers of subdigital lamellae on the fourth finger and toe, and a different shape of the black eye patch. The new species differs genetically from investigated congeners by percentage distance of 14.46% to 23.27% (cytochrome b gene).

Project description:A new species of Pareas is described from Yunnan Province, China, based on morphological comparisons and molecular data. Genetically, the new species is most closely related to the recently-described Pareas geminatus, for which we present new topotypic findings. The genetic divergence (uncorrected p-distance) of the cytb gene between the new species and congeners ranged from 6.14% to 24.68%. Morphologically, the new species can be distinguished from P. geminatus and all other congeners. Our work brings the total number of species within the genus Pareas to 22.

Project description:In this study, a new species of the genus Pseudocalotes is described from Yingjiang County, Dehong Dai and Jingpo Autonomous Prefecture, Yunnan Province, China, based on four female specimens. It can be distinguished from its congeners by the following combination of characters: (1) interoculabials 3 or 4; (2) canthals 5-7; (3) cicrcumorbitals 8-11; (4) 1 scale between rostral and nasal; (5) interparietal 1; (6) superciliaries 4-6; (7) supralabials 6-7, the 1st in contact with the nasal; (8) infralabials 6-8; (9) transverse gular fold and antehumeral fold present; (10) 2-3 enlarged scales between eye and ear; (11) nuchal crest single, consists of 3-5 erected spines; (12) dorsal crest row single, discontinuous and low, located between two keeled, parallel and enlarged scale rows; (13) enlarged postrictals absent; (14) scales around midbody 53-62, dorsal body scales heterogenous in size and shape; (15) midventrals smaller than dorsals; (16) subdigital scales on the 4th finger 20-26, and on the 4th toe 24-29; (17) dorsal background coloration light taupe with four irregular brown patches along the middle of dorsal; (18) inner lips wathet, tongue aurantiacus, throat bluish black. The population from Yingjiang County was nested within a highly supported lineage, formed a sister taxon with P. kakhienensis (SH 97/UFB 100) and according to the p-distance, the new species differed from its congeners by 14.5% to 35.2% for NADH dehydrogenase subunit 2 (ND2) and 15.5% to 25.0% for NADH dehydrogenase subunit 4 (ND4).

Project description:A new species of Acanthosaura from Yunnan, China, is described based on morphological and genetic data. The new species can be separated from all other species of the genus by having a different shape of the black eye patch, a different coloration of the postorbital and occipital spines and nuchal crest, and a different color of the gular pouch. Genetically, uncorrected sequence divergences of COI between the new species and investigated congeners ranged from 16.12% to 24.11%. The conservation status of the new species is also discussed.

Project description:A new species of Cyrtodactylus is described on the basis of five specimens collected from the karst formations of Zhenkang County, Yunnan Province, China. Cyrtodactylus zhenkangensis sp. nov. is recognized by having a unique combination of morphological characters, the most diagnostic being: 12-15 enlarged femoral scales on each thigh; 2-5 femoral pores on each thigh in males, 0-3 pitted scales on each thigh in females; eight or nine precloacal pores in a continuous row or separated by one poreless scale in males, 7-9 pitted scales in females; subcaudals enlarged, arranged alternately as single and double on anterior and mostly single at middle and posterior; dorsal surface of head with obvious reticulations. Phylogenetic analyses show that the new species is a member of the C. wayakonei species group and a sister taxon to a clade consisting of C. wayakonei and C. martini based on Maximum Likelihood analyses and Bayesian Inference and differs from its congeners by at least 12.0% genetic divergence in a fragment of the COI gene.

Project description:A new species of the Cyrtodactyluschauquangensis species group is described based on four specimens collected from the karst formations of Menglian County, Puer City, Yunnan Province, China. The new species can be separated from all other congeners by having a unique combination of morphological characters: a medium-sized body; ventrolateral folds present with interspersed small tubercles; seven precloacal pores in a continuous series in males, absent in females; enlarged femoral scales and femoral pores absent; two postcloacal tubercles on each side; and one or two rows of enlarged subcaudals. Genetically, the new species most closely related to C.wayakonei and the uncorrected sequence divergences of the ND2 gene and its flanking tRNAs between the new species and investigated congeners range from 7.2% to 18.4%.

Project description:A new species of the genus Amolops, Amolops tuanjieensis sp. nov., is described from Yunnan, China. The new species can be distinguished by the following characters: dorsolateral folds present; dorsal and ventral surfaces smooth; top of head and dorsum brown-red with irregular gray and dark spots; flank green; side of head black, from tip of snout, diffusing posteriorly to axilla, continuing as black streak below edge of dorsolateral fold; SVL 39.5-40.4 mm in males, 56.8-60.7 mm in females; tympanum distinct; supratympanic fold indistinct; vomerine teeth in two oblique rows between choanae, closer to each other than choanae; vocal sacs present; nuptial pads present; outer metatarsal tubercle absent, supernumerary tubercles absent; all fingertips expanded into discs; limbs dorsally brown with dark brown bars and irregular dark brown blotches.

Project description:Two new scorpionfly species, Panorpa reflexa sp. n. and Panorpa parallela sp. n., are described and illustrated from Yunnan Province, China. Panorpa reflexa can be readily differentiated from its congeners by the 3-shaped parameres in male genitalia. Panorpa parallela is unique for its parallel parameres in male genitalia. The number of Panorpa species is raised to four in Yunnan Province, and to 113 throughout China.

Project description:A new species, Takydromus yunkaiensis J. Wang, Lyu, & Y.Y. Wang, sp. nov. is described based on a series of specimens collected from the Yunkaishan Nature Reserve located in the southern Yunkai Mountains, western Guangdong Province, China. The new species is a sister taxon to T. intermedius with a genetic divergence of 8.0-8.5% in the mitochondrial cytochrome b gene, and differs from all known congeners by a combination of the following morphological characters: (1) body size moderate, SVL 37.8-56.0 mm in males, 42.6-60.8 mm in females; (2) dorsal ground color brown; ventral surface green to yellow-green, but light blue-green on chin and throat, posteriorly green in adult males; (3) dorsolateral lines paired, strikingly yellowish-white bordered by black above and below, invisible or indistinct in juveniles and adult females; (4) flanks of body blackish brown with light brown marks in adult males; (5) presence of four pairs of chin-shields; (6) four supraoculars on each side; (7) presence of a row of supracilary granules that separate supracilaries from supraoculars; (8) two postnasals; (9) enlarged dorsal scales in six longitudinal rows on trunk of body, with strong keel; (10) enlarged ventral scales in six longitudinal rows, strongly keeled in males, smooth but outermost rows weakly keeled in females; (11) enlarged and keeled lateral scales in a row above ventrals; (12) femoral pores 2-3 on each side; (13) subdigital lamellae 20-23 under the fourth finger, 23-30 under the fourth toe; and (14) the first 2-3 subdigital lamellae under the fourth toe divided.
