New lineages (green bars) are depicted within C. gramineus, C. malabaricus and the C. macrolepis species complex along with the other species from the Peninsular India. The clade comprising C. macrolepis and C. peltopelor sp. nov. is sister to the clade comprising all other members of Peninsular Indian Craspedocephalus (II). The Western Ghats C. malabaricus complex includes C. malabaricus, C. anamallensis and C. travancoricus (IV). C. trigonocephalus from Sri Lanka is nested within the Western Ghats sub-clade (III) along with C. strigatus, C. gramineus and C. occidentalis (V). Clade-I comprises species from Southeast Asia.
