Cnemaspis flaviventralis, a new species of gecko (Squamata: Gekkonidae) from the Western Ghats of Maharashtra, India

Abstract

Cnemaspis flaviventralis, a new species of day gecko, is described from the forests of Amboli, Sindhudurg District, Maharashtra State, northern Western Ghats, India. The new species was previously confused with the sympatric species Cnemaspis girii, C. indraneildasii, C. kolhapurensis and C. goaensis. It is distinguished from C. giri by having spine-like tubercles on flanks, granular dorsal scales intermixed with large, depressed, slightly keeled scales (vs. lack of spine-like tubercles on flanks, granular dorsal scales, intermixed with large smooth scales); from C. indraneildasii by having dorsal scales heterogeneous (vs. homogenous), lacking a series of enlarged median sub-caudal scales, and 28–29 (vs. 20) ventral scales across mid-body; from C. kolhapurensis by having heterogeneous (vs. homogenous) dorsal scalation, lacking spine-like tubercles on flanks and lacking pre-cloacal pores (vs. 24–28 pre-cloacal-femoral pores); and from C. goaensis by lacking pre-cloacal pores and lacking a series of enlarged median sub-caudal scales. We further provide partial mitochondrial 16S rRNA gene sequences for the new species and for the sympatric species C. girii, C. kolhapurensis and C. goaensis, and show that the new species is genetically distinct.Â
