摘要

We studied the population systematics of the group of the Common Indian wolf snake (Lycodon aulicus s.lat.) based on a series of specimens from throughout most of their geographic range. Two discrete species-groups couldbe discerned based on head dimensions, collar band pattern, hemipenal morphology and frontal-preocular-prefrontal-suproacularscale contact configurations (with outliers). The first one contains specimens agreeing with the morphologyof the name-bearing type of Lycodon aulicus; the other includes specimens agreeing with the morphology of Lycodonanamallensis (so far within the synonymy of L. aulicus), which is here revalidated at species-level. We formally report thepresence of the presumed Sri Lankan endemic Lycodon osmanhilli group taxa in the Indian peninsula and we synonymiseL. osmanhilli with the senior nomen L. anamallensis which is based on an Indian specimen. Our series of specimens showclear and sometimes non-overlapping geographical variations in ventral, subcaudal scale counts and relative tail lengthswithin both species.
