Sitana ponticeriana/Fan-Throated Lizard
Analysis (class): Small to medium-sized reptiles, male SVL 36.6-56.6 mm, females 36.4-52.1 mm; head-scales changeable, firmly keeled; supraciliary edge sharp; the fourth toe expanding great past third, the fifth toe missing; uncovered tympanum, no preanal or femoral pores, no clear dorsal peak; the nearness of enlarged scales on the parallel side of the storage section and a solitary broadened keeled scale on the thigh district. Scales on the dorsum inside the plain dark-colored line, checking are moderately bigger than the abutting littler scopes on the horizontal side of the body. Dewlap size changes from little to huge contingent upon the species. Sitana can be separated from their nearest living family Otocryptis by the nonattendance of the fifth toe and an uncovered tympanum (Deepak et al. 2016: 85).
Variety: Dewlap color is very unsteady in this variety with colored-fanned, medium-fanned, and white-fanned males.
Analysis: Sitana ponticeriana can be recognized from all the individuals from Sitana spinaecephalus clade in having a completely serrated dewlap with broad blue coloration and a huge orange spot versus a pitifully serrated dewlap with just a solitary blue line (Fig. 3 and 9A). Sitana ponticeriana can be effortlessly recognized from the three species in Sitana sivalensis complex by having a dewlap that broadens posteriorly past the lower arm addition. Sitana ponticeriana can be recognized from Sitana visiri sp. nov. in having a relatively littler dewlap that just stretches out up to 46% of the storage compartment length versus up to 56%. Sitana ponticeriana can be separated from different individuals from the S. ponticeriana Clade, Sitana devakai and Sitana bahiri, in having a dewlap that stretches out far posteriorly along the storage compartment (up to 46% versus 29% and 33%, separately). Sitana ponticeriana are medium-sized reptiles; guys (40.5 ± 2.5), females (41.8 ± 4.6). Subtleties on morphometric information, scale checks and body proportions of select characters for various examples are given in Table 3, 7 and 8. The dewlap is enormous, stretching out posteriorly up to 46% of the length of the storage compartment (Deepak et al. 2016: 87).
Distribution: Dry Coastal Northern and northwestern areas of Sri Lanka (from sea level to 50m above) and in India.
