Results of the phylogenetic analyses incorporating data for representatives of other lygoso- mine genera indicated that the basal phylogenetic split within Tropidophorus separated a clade of continental Indochinese species exclusive of T. cocincinensis and T. microlepis from one compris- ing T. cocincinensis, T. microlepis and species from Borneo, Sulawesi and the Philippines. Of the latter group, the two continental species form the sister taxon to a clade comprising the island species. Diversification among species in Indochina and among Borneo, the Philippines and Sulawesi was likely concentrated in the Miocene, with no apparent dispersal among these regions during the Pleistocene. The body depression recognized in several Indochinese species is likely to have occurred twice in parallel as an adaptation to saxicolous habitats.} }
