|Diagnosis||Diagnosis (genus): Cnemaspis is characterized by having slender digits with recurved clawed; two distal phalanges which are compressed, forming an angle with the basal portion of the digits, the lower surface having rows of plates; body more or less depressed; scales granular or tubercular above; tail is more or less cylindrical; pupils rounded; eyelid distinct all around the eye; males with or without precloacal or femoral pores; a well developed hypoischium, post-anal bones and sacs, and a reduced hyoid apparatus, with only one pair of basibranchials; the presence of three or four sternal ribs; interclavicles well developed and cruciform (in the Oriental species) or much reduced and with only a very small transverse arm (in the African species); adhesive toe pads absent (in the Oriental species) or present (in the African species); leaf toes and paraphalanges absent, having diurnal habits predominantly (Smith 1935; Gamble et al. 2012, Sayyed et al. 2019).|
Diagnosis. Maximum SVL 69.0 mm; 8–10 supralabials; six or seven infralabials; smooth ventral scales; no precloacal pores; 32–38 paravertebral tubercles; tubercles linearly arranged especially on upper flanks; lateral caudal furrows absent, dorsal caudal furrow weak; caudal tubercles restricted to a single paravertebral row; subcaudals smooth, bearing a medial row of enlarged scales; one postcloacal tubercle on each side; smooth, enlarged, plate-like femoral and subtibial scales; enlarged submetatarsal scales on first toe; 25–32 subdigital fourth toe lamellae; dorsal surfaces unicolor tan; large, subcircular black spots on shoulders and nape; and thin, yellow reticulation on side of neck (Tables 6,7 in Grismer et al. 2014).
|Comment||Type species: Cnemaspis boulengerii STRAUCH 1887 is the type species of the genus Cnemaspis STRAUCH 1887. “The genus Cnemaspis... the members of which are distinguished from other gekkonids in possessing a suite of characteristics, including round pupil, non-dilated clawed digits, a distinct eye-lid-structure around the eyes and diurnal habits.” (DAS 1993). Note that this diagnosis is only valid in Southeast Asia.|

|Etymology||Named after George Albert Boulenger (1858 - 1937), herpetologist at the British Museum of Natural History, London.|
