Abstract

We describe a new species of the genus , ., from Guizhou Province, China, based on morphological and molecular evidence. Phylogenetically, the new species is sister to , but is distinguishable from all known congeners by a combination of the following characters: small body size (snout-vent length 28.2‒32.2 mm in males; 38.6 mm in female); snout rounded, with no prominence on tip; single internal vocal sac; dorsal surface brown, rough, scattered with several small warts; chin clouded with blackish marking; pair of large symmetrical dark blotches on chest; vomerine teeth present; iris brown; tibiotarsal articulation reaching center of eye; nuptial pad slight; flank rough; mandibular symphysis weak; throat skin granular; and toes moderately webbed, formula I2‒2II1.5‒3III2‒3IV3‒2V. The genetic distances between the new species and were 2.9% and 5.4% for 16S rRNA and COI, respectively.

摘要

我们基于形态学和分子证据描述了一个来自中国贵州省的新种。在系统发育上，新种与最为接近，但通过以下特征的组合与所有已知近缘种区分开来：体型小（雄性鼻肛长 28.2‒32.2 毫米；雌性 38.6 毫米）；吻部圆钝，尖端无突起；单一的内声囊；背部棕色，粗糙，散布着几个小疣；颏部有黑色斑点；胸部有一对大而对称的暗斑；犁骨齿存在；虹膜棕色；胫跗关节到达眼睛中央；婚垫微弱；体侧粗糙；下颌骨联合弱；喉皮粒状；脚趾适度蹼状，趾式为 I2‒2II1.5‒3III2‒3IV3‒2V。新种与的 16S rRNA 和 COI 基因序列的遗传距离分别为 2.9%和 5.4%。
