|Comment||Diagnosis. A small-sized Cnemaspis (snout to vent length 28–33 mm in an adult males), which can be distinguished from all known congeners by the following combination of characters: postmentals separated by a small scale; nostrils are not in contact with first supralabial; 5–6 supra labials to angle of mid-orbit position and end of jaw at 8–9 supra labials; 36–38 interorbitals; throat scales keeled; 72–78 dorsal tubercles; dorsal tubercles small, rounded, pentagonal or hexagonal; intermixed with groups of large (3–4 in a transverse row), slightly carinated tubercles at the mid region of the body; lower part of flank with spine-like tubercles; upper part of flank with subconical scales; gular scales keeled; 28 midventrals; ventral keeled and imbricate; mid subcaudals small; 3–5 preanal pores; 4–5 femoral pores on each side; 11–12 subdigital lamellae and 4 basal lamellae in the 4th finger; 11–13 subdigital lamellae and 5 basal lamellae in the 4th toe.|
Comparisons: C. tropidogaster is congener with C. samanalensis sp. nov. from morphological characters. However, C. tropidogaster can easily be distinguished from C. samanalensis by the SVL, presence of groups of large scales (3–4) in transverse rows in dorsal body; of presence of non-prominent spine-like tubercles, the intraorbital, dorsal tubercle and ventral counts, and also from morphometric analysis.
Group: The C. tropidogaster group within Cnemaspis (7 species: Cnemaspis tropidogaster, C. clivicola , C. pava , C. pulchra, C. samanalensis, C. silvula and C. upendrai), is characterized by the presence of both femoral and precloacal pores, mid subcaudal scales large, and rough abdominal scales (Wickramasinghe et al. 2016).
Distribution: C. tropidogaster sensu stricto, earlier reported from India is currently believed to be a Sri Lankan endemic known only from the type specimens (Ganesh et al. 2011).
