Abstract

A new species of Southeast Asian Cnemaspis is described from the rocky foothills in the northwestern section of the Cardamom Mountains, Cambodia on the basis of a light colored chevron marking between the shoulders, tail tip white with black speckling, and several scale characteristics. This population's overall morphological similarity to southern Vietnam species demonstrates that Cambodia is an important biogeographical link between disjunct components of the Indochinese herpetofauna. This species represents the second known species of Cnemaspis from Cambodia and the ninth endemic species to be described from the Cardamom Mountains, highlighting the need for additional fieldwork in this area of Indochina.

Diagnosis

Cnemaspis neangthyi differs from all other Southeast Asian species of Cnemaspis in having the unique combination of a maximum SVL of 54.0 mm; supralabials 11–13; infralabials 11 or 12; forearm scales keeled; ventral scales smooth; femoral pores absent; two preanal pores (when present) contiguous; no linearly arranged tubercles on flanks; lateral caudal tubercles present; ventrolateral caudal tubercles present anteriorly; caudal tubercles not restricted to a single paravertebral row on each side; subcaudals not keeled; no single median row of keeled subcaudals; caudal tubercles encircle tail; enlarged median subcaudal scale row of smooth scales present; postcloacal spurs present; shieldlike subtibial scales absent; subtibial scales smooth; no enlarged submetatarsal scales beneath first toe; 22–25 subdigital lamellae under fourth toe; no white markings on flanks; no distinct large dark spots on neck; dark caudal bands present; light-colored chevron marking between the shoulders present; and tail tip white with black speckling.
