Ukuwelas' Rough-horn Lizard

Females have a snout–vent length of 36.4 to 37.9 mm. The upperside of the head, body and limbs are mostly grey-brown, while the tail is brown with dull serpentine markings. The chin, gular, and ventral scales are a mixture of dirty-white and red-brown. There is a white spot on the forehead, a Y-shaped brown marking on the area between the eyes, and a W-shaped pattern on the occiput. There are four grey diamond-shaped markings and black dots along the vertebrae. The labial scales are striped and there are two brown postorbital stripes past each eye. The upper side of both arms has a white ring. The back of the femur has a white line and the tibia has a white ring. The mouth is bluish-grey, the iris is copper-orange and the pupil is black. Males are slightly darker than females in colour. They also have a long complex rostral "horn" made of keeled acuminate scales.

Ukuwelas' rough-horn lizard is endemic to Salgala Forest in Kegalle District, Sri Lanka. The area, located at the northern edge of the wet bioclimatic zone, comprises lowland tropical rainforest at elevations of 120–325 m. The forest is separated from other forests by the Kelani and Maha rivers, smaller streams, and human agricultural cultivation. The species is known from four localities within Salgala forest and, like other Ceratophora lizards, seems to be a rather rare species. The species is found in thick leaf litter on the forest floor in dense patches of forest. Its microhabitat is poorly lit, with a light intensity of 455–687 Lux, moist, shaded, and warm, with an average temperature of 27.7–28.2 °C. It occurs alongside several other agamids, including the common green forest lizard, oriental garden lizard, brown-patched kangaroo lizard, and Sri Lankan agama.
