Nessia didactyla, also known commonly as the two-toed nessia[2] and the two-toed snakeskink,[3][4] is a species of skink, a lizard in the subfamily Scincinae of the family Scincidae. The species is endemic to the island of Sri Lanka.[2]
Habitat and geographic distribution
A low hill to submountain skink species, N. didactyla is known from localities that lie at 500–1,000 m (1,600–3,300 ft) of elevation, including Polgahawela,[1] Billegama, and Dewatura. Its preferred natural habitat is forest, but it has also been found in coconut plantations and home gardens.[1]
Description
N. didactyla has 24–28 scale rows at midbody. The snout is broad and blunt. The fronto-nasal is larger than the rostral, but slightly smaller than the frontal. The lower eyelid is scaly. Each limb has two digits, hence the scientific and common names. The pre-anals are slightly enlarged.
