Otocryptis wiegmannii, Length of head is scarcely one and a half times its breadth; snout longer than the orbit. Rostral is rather large, bordered by two labials and five scales, separated from nasal by a single pre nasal; mental narrow, longer than wide, much smaller than rostral; nasals large forming a mound with crater the rim the highest part; a large supra nasal, nearly as large as nasal; four canthus continuous with the elongate, broadly imbricating supraciliary series, canthus rostralis and supraciliary edge sharp. Upper head scales unequal, strongly keeled, those above the eye large and arranged in longitudinal series, the inner row extending forwards; a series of 4 or 5 small scales across the inter orbital region. Dorsal scales keeled, intermixed with larger ones, the upper and anterior pointing backwards and upwards, the lower and posterior more or less backwards and downwards; ventral scales largest, strongly keeled. Limbs very long and slender, with very large, strongly keeled scales; fourth toe extending well beyond third; the hind limb reaches to far beyond the top of the snout. Tail round, slender, covered with sub equal keeled scales. Male with a low nuchal fold and a very large gular appendage, which extends backwards to about the middle of the belly; it is covered with very large scales. Female is without nay trace of appendage. SUP: 8-12, INF: 8-10, MBS: 78, SVL: 64-70 mm; TAL: 180 mm; HL: 19 mm; AG: 27 mm (Deraniyagala, 1953; Smith, 1935 Taylor, 1953).

The body color is changeable from dull brown to reddish brown, head blackish brown. Brownish above with darker markings; a dark cross-bar between the eyes and usually dark bars across the back, best marked in the young; generally a light band from the eye to the angle of the mouth; males often with a light stripe along each side of the back, light brownish below; throat of female sometimes dark bluish. A distinctly maroon patch is present laterally on dewlaps of males. Limbs light brown, tail indistinctly banded with broader dark bands and light narrow bands (Deraniyagala, 1931; Deraniyagala, 1953; Smith, 1935 Taylor, 1953).

Otocryptis wiegmannii is a ground-dwelling lizard preferring the neighborhood of shady forest streams in the idle hills of central Sri Lanka and the parts of the west and south (Das & De Silva, 2005; Manamendra-Arachchi & Liyanage, 1994; Smith, 1935). This species is widely distributed throughout the wet zone of Sri Lanka up to 1340 m elevation and endemic to Sri Lanka. The species is relatively abundant wherever it occurs, these lizards being frequently seen in anthropogenic habitats such as home gardens in which there is adequate leaf litter and shade. At night they climb in to small shrubs where they sleep at the periphery of branches (Das & De Silva, 2005; De Silva et al., 2005a).

When threatened it may run quickly it often adopts a bi-pedal method of locomotion and attempt to climb saplings and trees, the reduced size of the outer toe presumably being a handicap in climbing (Karunarathna & Amarasinghe, 2007a; Das & De Silva, 2005; Manamendra-Arachchi & Liyanage, 1994; Smith, 1935; Taylor, 1953). Otocryptis wiegmannii feeds on insects, grubs and tender shoots. Some times feed on geckos (De Silva et al., 2005a).

The female digs a nest hole in the ground and deposits 3-5 eggs in October-January. The eggs are 10-17 x 7-7.5 mm, these hatch 57-70 days later (Das & De Silva, 2005). During the breeding season the males show territorial behaviors (Karunarathna & Amarasinghe, 2007a).

Conservation status: large, widely dispersed, stable population (Manamendra-Arachchi & Liyanage, 1994), Least Concern (Bahir & Surasinghe, 2005).
