Monilesaurus rouxii

Roux's forest lizard, also called the forest bloodsucker, is an arboreal, diurnal agamid lizard endemic to the hills of peninsular India. It has an olive-brown body with a lighter belly, a dark band along the side of the head onto the neck, and dark lines radiating from the eye. In males the upper head, nape and throat pouch turn brick-red in the breeding season, and two small groups of spines sit on each side of the neck (Wikipedia, general species account).

It is reported largely from wet hill forest, except in the far south, at 100–900 m elevation, in habitats from moist evergreen to secondary deciduous forest. It is an insect-eater that hunts by day both on the ground and in trees. It lays eggs, breeding between April and September. Total length reaches up to 30 cm, though 25 cm is more common.
