Tropidophorus beccarii, also known commonly as Beccari's keeled skink and Beccari's water skink, is a species of lizard in the subfamily Lygosominae of the family Scincidae. The species is endemic to the island of Borneo.

Etymology

The specific name, beccarii, is in honor of Italian botanist Odoardo Beccari.[3]

Geographic range

On the island of Borneo, T. beccarii is found in Brunei, northern Kalimantan (Indonesia), Sabah, and Sarawak (Malaysia).[1][2]

Habitat

The preferred natural habitats of T. beccarii are forest and freshwater wetlands, at altitudes from sea level to 1,000 m (3,300 ft).[1]

Description

Dorsally, T. beccarii is reddish brown, with dark brown crossbands. The flanks have whitish spots. Ventrally, it is yellowish.

T. beccarii may attain a snout to vent length (SVL) of 9.8 cm (3.9 in).[4] The largest specimen measured by Boulenger had an SVL of 8 cm (3.1 in), and a tail length of 10.6 cm (4.2 in).[5]

Diet

T. beccarii preys upon water insects.[4]

Reproduction

T. beccarii is viviparous.[2] Average litter size is four.[1]
