| 1 | A New Species of the Genus Rhabdophis Fitzinger,1843(Squamata:Colubridae)in Southwestern Sichuan,China显示文摘The genus Rhabdophis is a group of widely distributed snakes with more than 20 species.Recent field surveys uncovered a species in southwestern China,which has long been considered as R.pentasupralabialis.Combined molecular and morphological analyses revealed it as a new species Rhabdophis chiwen sp.nov.Based on 12 specimens,this new species is distinguished by the following characters:1)dorsal body saddlebrown,dorsal scales typically with black margins forming spots and stripes,the margin of the outer row forming two faint dorsolateral black cross-bars alongside body;2)ventral scales 151–159,the outer margin of ventral scales and several lateral rows of dorsal scales forming ventrolateral longitudinal brownish-red coloration,with faint black spots in the middle of ventral scales;3)a black oblique stripe present below eyes,often with a black spot between the 2 nd and 3 rd supralabial and a black stripe on the 5 th supralabial;4)eyes dark khaki,pupils black;5)infralabials usually 7,the first four in contact with anterior chin-shields;6)temporal scales 1+1;7)dorsal scales in 15 rows,feebly keeled except the outer 1–2 rows;8)anal scale divided;subcaudals 45–59;9)preocular 1 and postoculars 3(occasionally 2);10)body medium-sized(snout-vent length:adult males 404–431 mm,adult females 409–476 mm);11)tail moderate(tail length/total length in adult males 0.205–0.238,in adult females0.172–0.193).With the discovery of this new species,the total number of species in genus Rhabdophis is 28 with 12 th species known to occur in China. | Yige PIAO Zening CHEN Yanqing WU Shengchao SHI Hirohiko TAKEUCHI Teppei JONO Masaya FUKUDA Akira MORI Yezhong TANG Qin CHEN Li DING | 2020 | Asian Herpetological Research2020，11，2： | 0 |
| 2 | Reevaluation of the Taxonomic Status of a Poorly Known Gecko, Gekko liboensis(Reptilia: Squamata)显示文摘Gekko liboensis Zhou and Li, 1982 is a poorly known gecko originating from Libo, Guizhou, southern China. Since the original description based on a single female from Libo, only three specimens(two females and one juvenile) have been reported from the type locality. Because of its close morphological resemblance to G. hokouensis Pope, 1927, G. liboensis is required to be reevaluated for its taxonomic status by studies based on additional specimens. Here we report for the first time the morphological features of 31 newly obtained specimens of G. liboensis from type locality and others, including males, and compare them with those of related species, chiefly on the basis of information from the literature. In addition, specimen-based comparisons were also made with G. hokouensis and an undescribed cryptic species known from the Ryukyus Islands, Japan. Results showed that the species is distinguished from its congeners in having a larger body size(60–91 mm), 0–2 small internasals, 10–13 supralabials, 10–13 infralabials, smooth enlarged tubercles present on the dorsum forming 4–10 irregular rows at the midbody but absent on the four limbs and tail, both fingers and toes without developed interdigital webs, a single cloacal spur on each side, and 10–12 precloacal pores in males. It most resembles G. hokouensis and its cryptic species but is clearly differentiated by having a larger body size, a predominantly absent internasal, fewer number of dorsal tubercle rows, larger number of precloacal pores, and conspicuous white marks on the dorsum and head. Judging from these results, we confirmed the taxonomic validity of G. liboensis. In addition, the geographic distribution of this gecko on the basis of obtained data was briefly discussed. | Teppei JONO Li DING Takuma KAITO Yezhong TANG Mamoru TODA | 2015 | Asian Herpetological Research2015，6，3： | 0 |
