|Distribution||Sri Lanka (hills around Kandy)|
Type locality: mountains of Ceylon (fide Wermuth 1965); type locality of neotype: Agarapatana, Hatton, Sri Lanka, (N 06° 50’ 58.1” E 080° 40’ 35.0”, elevation 1524m).

|Types||Neotype. NMSL 20061101, Adult male, 33.48 mm SVL, 17.09.2006, collected by L . J. Mendis Wickramasinghe and D. A. I. Munindradasa.|
Holotype: NMSL2004.1.1 (Adult male), 27.12.2003, collected by L . J. Mendis Wickramasinghe [ranwellai]
|Diagnosis||Diagnosis. A medium-sized Cnemaspis (snout to vent length 30–35 mm in adults), which can be distinguished from all known congeners by the following combination of characters: postmentals separated by a small scale; nostrils not in contact with first supralabial; seven supra labials to angle of mid-orbit position and end of jaw at nine supra labials; 26 interorbitals; throat scales smooth; 74–76 dorsal tubercles; dorsal tubercles small, rounded, pentagonal or hexagonal; absence of groups of carinated large scales in dorsal body; spinelike tubercles present on flanks; 20 midventrals; ventral scales smooth and imbricate; mid-subcaudals large; no preanal pores; 13–14 femoral pores on each side; 10 subdigital lamellae and 4–5 basal lamellae in the 4th finger; 11 subdigital lamellae and 6 basal lamellae in the 4th toe; dorsal part of tail with large flushed and smooth scales, lower border with elongated diamonds.|
C. scalpensis is congener with C. ranwellai very closely and C. alwisi sp. nov. from morphological characters. However, C. scalpensis can easily be distinguished from both by interorbital and supralabial counts, and from C. ranwellai by throat colour, infralabial and dorsal tubercle counts and lamellae formulae and from C. alwisi by internasal, dorsal tubercle, ventral subcaudal, femoral pores and loreal counts and lamellae formulae.
Diagnosis (ranwellai): A medium-sized Cnemaspis (average snout to vent length 31 mm in an adult male, and 37 mm in an adult female), which can be distinguished from all known congeners in showing the following combination of characters: nostrils are not in contact with first supralabial; nostrils smaller than the ear opening, eight supra labials to angle of mid-orbit position and end of jaw at 12–13 supra labials; dorsal tubercles 56–58; dorsal tubercles small, rounded, pentagonal or hexagonal; with spine-like tubercles on flanks; midventrals 22; ventral smooth; subcaudals enlarged; no preanal pores; 12–15 femoral pores on each side; 13–15 subdigital lamellae and 5–6 basal lamellae in the 4th digit; a dorsally prominent narrow black stripe on the neck, with a sharp yellowish margin; throat of males bright yellow, with small black stripes and / or spots; infra-labial margins of males with black stripes; tail cylindrical, with spine-like tubercles on the dorsal and lateral sides.
|Comment||Group: The C. scalpensis group (3 species: Cnemaspis scalpensis, C. gemunu and C. phillipsi), is characterized by femoral pores present while precloacal pores are absent, mid subcaudal scales extremely large, and smooth abdominal scales (Wickramasinghe et al. 2016).|
Synonymy: C. ranwellai is a synonym of C. scalpensis fide MANAMENDRA-ARCHCHI et al. 2007.
