Sitana ponticeriana — Pondichéry Fan-throated Lizard
The populations in this part of Sri Lanka were assigned to a new species, Sitana bahiri, for a few years, before being sent back to S. ponticeriana from whence they came.
These small lizards are active on the warm sands, dashing to and fro in search of tasty bugs. Adult males can extend a remarkably large and brightly colored flap of skin on their throats (a dewlap) to attract females and intimidate other males, much like the Anolis lizards of the New World. The second and third pictures above are of an adult male with a large blue dewlap, but unfortunately for me he never felt the need to extend it in my presence.
