DiagnosisDiagnosis: Cnemaspis bidongensis sp. nov. differs from all other Southeast Asian species of Cnemaspis in having the unique combination of adult males reaching at least 56.1 mm SVL, adult females reaching 58.1 mm SVL; nine or 10 supralabials; 7–9 infralabials; enlarged, elongate mental scale; keeled ventrals; no precloacal pores; moderately prominent, randomly arranged, dorsal tubercles; 21–26 paravertebral tubercles; no tubercles on lower flanks caudal tubercles encircling tail; no tubercles in lateral caudal furrows; ventrolateral caudal tubercles present anteriorly; subcaudals keeled; a median row of enlarged, keeled subcaudals; one or two postcloacal tubercles on each side; no enlarged femoral, subtibial, or submetatarsal scales; subtibials keeled; 26–30 subdigital lamellae on fourth toe; dark and light caudal bands distinct in both sexes; and no dark mottling on lateral portions of belly. These differences are summarized across all species of the C. kendallii species group in Table 1 and all across Southeast Asian species in Wood et al. (2013:Table 4) and GRISMER et al. 2014 (Tables 6,7).
