Three more novel species of South Asian Cnemaspis Strauch, 1887 (Squamata, Gekkonidae) from Kalakad Mundanthurai Tiger Reserve, Tamil Nadu, India

We describe three distinct, small-bodied, scansorial species of south Asian Cnemaspis from Kalakad Mundanthurai Tiger Reserve, Tirunelveli district, Tamil Nadu, India—Cnemaspis azhagusp. nov. from Thirukurungudi forest range, Cnemaspis mundanthuraiensissp. nov. from Mundanthurai forest range and Cnemaspis kalakadensissp. nov. from Kalakad forest range. Phylogenetic analyses using a partial sequence of the mitochondrial ND2 gene and general morphology places each of the three new species in the beddomei, gracilis and littoralis clades, respectively. The three new species are diagnosed from all other described members of their respective clades by a suite of differing morphological characters including snout vent length, number of dorsal tubercle rows at mid-body, number of paravertebral tubercles, presence or absence of spine-like scales on flanks, number of ventral scales across belly at mid-body, number of ventral scales from mental to anterior border of cloaca, number of lamellae under digit IV of pes, number of femoral and/or precloacal pores and poreless scales separating these series, as well as subtle colouration differences. We also provide some novel characters of tail tuberculation of the three new species described herein. With the discovery of these three new species, eight species of geckos including five Cnemaspis are now known to be endemic to KMTR.
