දේවකගේ තැලි කටුස්සා [Devakage Theli Katussaa]/Devaka's Fan-throated Lizard (Sitana devakai)


Fan throated Lizard inhabiting dry coastal areas of  the North, Northwestern and Southeastern part of the country was formerly considered as a single species Sitana ponticeriana which is also recorded from the India. However with the recent taxonomic changes now it is considered that Sri Lanka is home to two distinct endemic species, one occurs in the Southeastern coastal areas (Sitana bahiri) and other in the Northern and Northwestern part of the island (Sitana devakai).

Devaka's Fan-throated Lizard is an endemic lizard confine to the dry coastal areas of the north and north western part of the island. However sometime it is recorded even 10-60 km from the nearest beach. It is active during the day time. Territorial behaviors of Sitana devakai are similar to its Southeastern congener Sitana bahiri.

Maduwage K. et al. recorded of a rare occasion of observing this snake on a shrub up to about 60cm above the forest floor. Furthermore according to them Lowland Hump-nosed Pit Viper is absent in anthropogenic habitats. Above specimen was photographed on a banana shrub - considerable height above the ground- But habitat can't be considered as a primary forest though entirely not a home garden ( 6°22'24.18"N,  80°27'8.22"E). Location -though sort of anthopogenic habitat- is very close to the Gin river as well as Sinharaja forest.
