We describe two new species of South Asian Cnemaspis from far northern peaks of the Northern Western Ghats of Maharashtra, India. The two new species are the most northernly distributed representatives of the girii clade and are phylogenetically and morphologically allied to C. uttaraghati. The new species are 15.0% divergent from C. uttaraghati in pairwise uncorrected ND2 sequence data, 9.9 % from each other, and over 17.5-18.8% from other members of the girii clade. The two new species can easily be distinguished from most members of the girii clade by a combination of non-overlapping morphological characters such as body size (maximum snout to vent length 35-43 mm), low number of dorsal tubercle rows (6-11), having irregular paravertebral tubercles, and high subdigital lamellae counts; and from each other and C. uttaraghati by the number of midventral scales across belly, the number of subdigital lamellae, and the number of poreless scales separating series of femoral pores. The new species and C. uttaraghati are distributed within 10-25 km of each other, providing an example of extreme micro-endemism in the Northern Western Ghats.
我们描述了来自印度马哈拉施特拉邦西高止山脉最北端山峰的两种南亚弯脚虎属新物种。这两个新物种是吉里分支分布最靠北的代表,在系统发育和形态上与乌塔拉加蒂弯脚虎相关。在成对未校正的ND2序列数据中,新物种与乌塔拉加蒂弯脚虎的差异为15.0%,彼此之间的差异为9.9%,与吉里分支的其他成员的差异超过17.5 - 18.8%。这两个新物种可以通过一系列不重叠的形态特征轻松地与吉里分支的大多数成员区分开来,这些特征包括体型(吻端到泄殖腔的最大长度为35 - 43毫米)、背侧瘤排数少(6 - 11排)、有不规则的椎旁瘤以及趾下瓣数量多;并且可以通过腹部腹中线鳞片的数量、趾下瓣的数量以及分隔股孔系列的无孔鳞片的数量与彼此以及乌塔拉加蒂弯脚虎区分开来。新物种和乌塔拉加蒂弯脚虎的分布距离彼此在10 - 25公里以内,这是西高止山脉北部极端微特有现象的一个例子。
