CommentComparisons. Cnemaspis punctatonuchalis sp. nov. can be diagnosed from all other Southeast Asian Cnemaspis in having pairs or trios of enlarged, elongate, isolated tubercles on the flanks and a black, neck patch enclosing a white to yellow ocellus.

Diagnosis. Adult males reaching 49.6 mm SVL, adult females reaching 43.8 mm; eight supralabials; seven or eight infralabials; gulars smooth; forearm scales keeled; subtibials, ventrals, subcaudals smooth; dorsal tubercles keeled; 24–27 paravertebral tubercles; enlarged, elongate pairs or trios of isolated tubercles on flanks; dorsolateral, lateral, and ventrolateral caudal tubercles present only anteriorly; caudal tubercles do not encircle tail; caudal tubercles absent from lateral, caudal furrow; middorsal caudal furrow absent; median row of smooth, enlarged subcaudals; no pore-bearing, precloacal scales; 1–3 postcloacal tubercles; shield-like subtibials and enlarged, submetatarsals absent; 29–31 subdigital lamellae on fourth toe; no dark, longitudinal, gular markings or blotches; head not yellow in adult males; black neck patch enclosing a white to yellow ocellus present in adult males; no dark shoulder patch enclosing white to yellow ocellus; no prominent, yellow to white, prescapular crescent or transverse bars on flanks. These differences are summarized across all species in TABLES 1 and 2 in GRISMER et al. 2010.

Diagnosis. Maximum SVL 49.6 mm; eight supralabials; seven or eight infralabials; smooth ventral scales; no precloacal pores; 24–27 paravertebral tubercles; body tubercles semi-linearly arranged, present on flanks; tubercles absent from lateral caudal furrows; ventrolateral caudal row of tubercles present anteriorly; lateral caudal row of tubercles present; caudal tubercles do not encircle tail; subcaudals smooth, bearing an enlarged median scale row; 1–3 postcloacal tubercles on each side of tail base; no enlarged femoral, subtibial or submetatarsal scales; subtibials smooth; 29–31 subdigital fourth toe lamellae; white ocelli on brachia and side of neck in males; throat and subcaudal region orange in males (Tables 6,7 in Grismer et al. 2014). 
EtymologyThe specific epithet punctatonuchalis, is derived from the Latin adjective punctatus, meaning spotted and the Latin noun nuchalis, meaning neck and is in reference to the large, white ocellus on the side of the throat.
