Abstract

We describe two new medium-bodied, nocturnal species of South Asian Cnemaspis from the southern Western Ghats, Tamil Nadu, India in an integrative taxonomic framework. The two new species are phylogenetically and morphologically allied to the wynadensis clade and can be distinguished from other species of the wynadensis clade and each other by a combination of nonoverlapping morphological characters including body size, homogeneous dorsal pholidosis, the number of femoral pores and poreless scales separating these series, the number of ventral scales across the midbody and longitudinal scales from mental to cloaca, the number of dorsal granules around the body; and an uncorrected pairwise ND2 sequence divergence of 8.2–22.9 % (16S 4.2–12.2 %) from all other members in the clade. These are the first members of the wynadensis clade known from south of the Palghat Gap apart from C. bireticulata, a putative junior synonym of C. sisparensis that is likely to be distinct owing to morphological differences and geographic distance. Cnemaspis sanctus sp. nov. is from low coastal hills in Kanyakumari District at the southern tip of the Western Ghats and Cnemaspis persephone sp. nov. is from the Anaimalais, Anaimalai Tiger Reserve. Many more undescribed species of the wynadensis clade and South Asian Cnemaspis are likely to be found across the southern Western Ghats.
