TypesHolotype: BMNH (male), 30.4 mm SVL; purchased from Col. Beddome (formerly a syntype of Cnemaspis tropidogaster). 
DiagnosisDiagnosis: Cnemaspis australis differs from its peninsular Indian and Sri Lankan congeners by a combination of the following characters. Maximum SVL 30.4 mm; paired postmentals separated by 1 or 2 small scales; each postmental bounded by 3 scales including medial scale; dorsal scales heterogeneous with smooth and carinate scales; spine-like tubercles absent on flank; ventrals weakly keeled; 3 preanal and 4 or 5 femoral pores on each side; tail with enlarged conical scales forming whorls; subcaudals keeled, 2 smaller scales between single larger ones in median series; supralabials to angle of jaws, 8; subdigital lamellae on digit IV of pes, 15 [from MANAMENDRA-ARACHCHI et al. 2007]. 
CommentAbundance: only known from the type specimen (Meiri et al. 2017). 
EtymologyThe species name ‘australis’ is Latin for ‘southern’; an allusion to the type locality being very nearly at the southernmost tip of the Indian peninsula.
