Dasia haliana
Habitat
Arboreal
Range
Endemic to Sri Lanka
Size
Snout–vent about 8cm
The Ceylonese dasia, also called Haly's tree skink, is the only arboreal skink in Sri Lanka. It was long thought to occur also in the Western Ghats, but taxonomic studies showed it to be a Sri Lankan endemic, distinct from the Indian Dasia subcaeruleum. It has a snout-vent length of about 8 cm and differs from its relatives in having fewer scale rows at midbody (22 to 24) and an enlarged pair of vertebral scale rows. The snout is pointed and the dorsal scales have three or five blunt keels (Wikipedia, general species account).
