A new species of odd-scaled snake in the genus Achalinus is described from Ningshan County, Shaanxi Province, China, based on seven female specimens. Morphologically, the new species can be distinguished from its congeners by the following combination of characters: (1) dorsum iridescent and uniformly dark brown in preservative, longitudinal vertebral line absent; (2) light brown beneath; (3) dotted black streak in the middle of the subcaudals absent; (4) tail length relatively short, TaL/ToL 12–16%, in females; (5) fewer subcaudals, 41–46 in females; (6) dorsal scales 23 rows throughout, strongly keeled; the outer-most rows on both sides are also keeled and slightly enlarged; (7) one loreal; (8) internasal not fused to prefrontal; (9) suture between internasals is similar in size when compared to the suture between prefrontals; (10) preocular and postocular absent; (11) 6 supralabials; (12) 5 infralabials, the first 3 (rarely 2) touching the first pair of chin shields; (13) 3 pairs of chin shields. A phylogenetic analysis using mitochondrial gene, cytochrome c oxidase subunit 1 (CO1), showed that this new species forms a monophyletic group with strong support. In addition, the uncorrected p-distances between the new species and other known congeners ranged from 3.4% to 13.0%. The recognition of the new species increases the number of described Achalinus species to 21.

We describe a new species of the genus Achalinus Peters, 1869 from Daming Mountain, Shanglin County, Nanning City, Guangxi Zhuang Autonomous Region, China, based on a single adult male specimen. It can be distinguished from all the other species in Achalinus by a combination of the following morphological characters: (1) a bright yellow collar around the neck, extending forward to the ventral of the head; (2) tail length comparatively long, TaL/Tol ratio 0.25; (3) DSR 23-23-23, moderately keeled; (4) VS 3+162; (5) SC 74, unpaired; (6) cloacal plate entire; (7) SPL 6, the fourth and fifth in contact with the eye; (8) IFL 6, the first three touching the first pair of chin shields; (9) a single loreal; (10) length of suture between internasal significantly longer than that between prefrontal, LSBI/LSBP ratio 1.34; (11) two pairs of chin shields; (12) longitudinal vertebral line absent. In addition, the uncorrected p-distances between the new species and other known congeners ranged from 6.3% to 25.4% for the cytochrome c oxidase subunit 1 (CO1). With the addition of the new species the total number of described Achalinus species is increased to 23 of which 17 are found in China.

A new species of the genus Hebius Thompson, 1913 is described from Yingjiang County, Dehong Dai and Jingpo Autonomous Prefecture, Yunnan Province, China, based on molecular and morphological evidence. It can be distinguished from its congeners by the following set of characters: (1) dorsal scale rows 19–17–17, feebly keeled; (2) ventrals 146–151; (3) nasal complete, nostril in the middle of the nasal; (4) supralabials 9, the fourth to sixth in contact with the eye; (5) infralabials 10–11, the first 5 touching the first pair of chin shields; (6) preoculars 2; (7) postoculars 3; (8) temporals 3, arranged in two rows (1+2); (9) maxillary teeth 31, the last 4 slightly enlarged, without diastema; (10) tail comparatively long, TAL/TL ratio 0.334 in the male; (11) dorsolateral series of irregular orange or ochre yellow blotches, extending from the neck to the posterior part of the tail; and (12) venter pale orange, tips of ventrals with subrectangular black blotches. All Hebius specimens were strongly recovered as monophyletic, in which Hebius taronensis (Smith, 1940) and Hebius venningi (Wall, 1910) were monophyletic as sister to the Yingjiang County specimens. According to the p‐distance of cytochrome b, the new species differs from its congeners by 9.7–15.4%.

A new species of the genus Hebius Thompson, 1913 is described from Youjiang District, Baise City, Guangxi Zhuang Autonomous Region, China, based on a single adult female specimen. It can be distinguished from its congeners by the following combination of characters: (1) dorsal scale rows 19-17-17, feebly keeled except the outermost row; (2) tail length comparatively long, TAL/TL ratio 0.30 in females; (3) ventrals 160 (+ 3 preventrals); (4) subcaudals 112; (5) supralabials 9, the fourth to sixth in contact with the eye; (6) infralabials 10, the first 5 touching the first pair of chin shields; (7) preocular 1; (8) postoculars 2; (9) temporals 4, arranged in three rows (1+1+2); (10) maxillary teeth 30, the last 3 enlarged, without diastem; (11) postocular streak presence; (12) background color of dorsal brownish black, a conspicuous, uniform, continuous beige stripe extending from behind the eye to the end of the tail; (13) anterior venter creamish-yellow, gradually fades to the rear, with irregular black blotches in the middle and outer quarter of ventrals, the posterior part almost completely black. The discovery of the new species increases the number of species in the genus Hebius to 51.

We described a new species of genus Pareas from Baise City, Guangxi Zhuang Autonomous Region, China, based on morphological and molecular evidence. Pareas baiseensis sp. nov. is distinguished from its congeners by the combination of (1) Yellowish-brown body colouration; (2) Frontal subhexagonal to diamond-shaped with its lateral sides converging posteriorly; (3) The anterior pair of chin shields is longer than it is broad; (4) Loreal not in contact with the eye, prefrontal in contact with the eye, two or three suboculars; (5) Rows of 15–15–15 dorsal scales, five rows of mid-dorsal scales keeled at the middle of the body, one vertebral scale row enlarged; (6) 187–191 ventrals, 89–97 subcaudals, all divided, cloacal plate single; (7) Two postocular stripes, the nuchal area forming a dark black four-pointed fork collar with the middle tines shorter than the outside tines. The genetic divergence (uncorrected p-distance) between the new species and other representatives of Pareas ranged from 13.9% to 24.4% for Cytochrome b (Cyt b) and 12.1% to 25.5% for NADH dehydrogenase subunit 4 (ND4). Phylogenetic analyses of mitochondrial DNA gene data recovered the new species from being the sister taxon to (P. boulengeri + P. chinensis) from China.

A new species of the soft-shelled turtle genus Pelodiscus is described based on seven specimens from Huangshan, southern Anhui Province, China. The new species, Pelodiscus huangshanensis sp. nov., is distinguished from other species in the genus Pelodiscus by the following characteristics: (1) Small size (maximum carapace length of 101.16 mm and maximum body length of 190 mm); (2) keel high; (3) tiny yellowish-white spots on the throat; (4) no black pinstripes around the eyes; (5) white longitudinal bands on both sides of the neck in juveniles, absent in adults; (6) plastron yellowish-white, and only a dark patch on each side of the armpit; (7) many tubercles on the dorsal surface, but indistinct in the center; and (8) entoplastron “⌒” shaped. The phylogenetic relationships of the species in Pelodiscus were reconstructed using the sequences of cytochrome b (cyt b) and NADH dehydrogenase subunit 4 (ND4) genes. The new species formed a monophyletic clade with strong support. The uncorrected pairwise distances between the new species and other representatives of Pelodiscus ranged from 5.4% to 9.2% for cyt b and 4.1% to 7.6% for ND4. The new species brings the number of species of the genus Pelodiscus to six; five species are distributed in China, with three species endemic to China.
