CommentSynonymy: Lycodon osmanhilli has been considered as a subspecies or variant of Lycodon aulicus (see LANZA 1999 for discussion). Listed as synonym of L. aulicus by WALLACH et al. 2014: 391. Ganesh & Vogel have resurrected L. anamallensis and synonymzed L. osmanhilli with it.

Habitat: partly arboreal (Harrington et al. 2018). 
EtymologyNamed after the type locality.
L. osmanhilli was named after the collector of the type, W.C. Osman Hill.
