| Diagnosis | Diagnosis: A medium-sized Hemidactylus, SVL 80 mm (n=8 including holotype). Dorsal pholidosis hetero- geneous, comprising subcircular granular scales intermixed with fairly regularly arranged longitudinal rows of enlarged, strongly keeled, pointed tubercles, that are heterogeneous in shape and size, extending from occiput to tail; enlarged tubercles on the two most medial parasagittal rows smaller than rest on dorsum and these rows most broadly spaced from one another, gradually increasing in size and becoming conical towards flanks, last two rows on flanks are smaller and strongly conical; 15 or 16 dorsal tubercle rows at mid-body, 16–18 tubercles in paraverte- bral rows. Ventrolateral folds indistinct; about 29–34 ventral scale rows at mid-body. Digits with enlarged scansors, lamellae in straight transverse series, all divided except the apical and a few basal that are undivided, nine or 10 lamellae beneath first digit of manus, eight or nine beneath first digit of pes and 10 or 11 beneath fourth digit of manus and 10–12 beneath fourth digit of pes. Males with 21–25 femoral pores on each side separated by two or three poreless scales. Tail with 4–8 much enlarged, strongly keeled, conical tubercles forming whorls; median row of subcaudal plates large, covering almost entire portion of the tail; two subequal postcloacal spurs on each side that are much smaller than dorsal tubercles at mid-body. Dorsal colouration brown with five indistinct transversely arranged dark saddle-shaped markings running from the occiput to the sacrum, limbs with purple-grey bars (Khandekar et al. 2020: 89). |
| Comment | Habitat: The holotype was collected about an hour after dark on a high rock wall along the mountain road leading up to Solakkadu. Sympatry: The only sympatric gecko was a Hemidactylus cf. triedrus at the base of the rock wall. Agarwal et al. did not see any large Hemidactylus above this elevation and found H. cf. graniticolus below 500 m asl. |
| Etymology | The specific epithet is a toponym for the Kollimalai Massif, the only known locality of the species. |
