SynonymHemiphyllodactylus kolliensis AGARWAL, KHANDEKAR, GIRI, RAMAKRISHNAN & KARANTH 2019 
DistributionIndia (Tamil Nadu)

Type locality: near Selur Nadu, Kolli Hills (known locally as Kollimalai), Namakkal District, Tamil Nadu, India (11.219° N, 78.354° E, 1170 m elevation.  
Reproductionoviparous (manual imputation, fide Zimin et al. 2022) 
TypesHolotype: CES G138, Adult male, collected on 23 March 2011 by Aniruddha Datta-Roy and Ishan Agarwal. Paratypes: AK 276–278, Adult females, same collection data as holotype except, collected on 20 April 2011, AK 277 from near Semmedu (11.268° N, 78.321° E, 1180 m) and AK 278 from near Thinnanurnadu (11.242° N 78.330° E, 1100 m). 
DiagnosisDiagnosis: Hemiphyllodactylus kolliensis sp. nov. can be distinguished from other members of the genus by a combination of maxi- mum SVL of 39.3 mm; 10–12 chin scales; postmentals not enlarged; 9–11 SL; 10 or 11 IL; 16 dorsal scales and 10–13 ventral scales at mid-body contained within one longitudinal eye diameter; three or four subdigital lamellae on the first finger and four or five on toes; lamellar formula of manus and pes 2222; males with 10 pored precloacal scales separated by 5 unpored scales from a series of 8 pore-bearing femoral scales on each thigh; no plate-like subcaudals; dark postorbital stripe just extending onto trunk; longitudinal markings on nape extending beyond forelimb insertion; dorsal pattern of few scattered light spots and indistinct reticulations or dark paravertebral reticulations enclosing light paravertebral spots; postsacral marking with light-coloured anteriorly projecting arms and belly stippled with black.

Comparisons: Hemiphyllodactylus kolliensis sp. nov. can be distinguished from Hemiphyllodactylus aurantiacus by the presence of 2 lamellae under toes four and five (vs. 3 lamellae under toes four and five), greater number of pore-bearing precloacal scales in males (9 vs. 6–7) and fewer unpored scales separat- ing the pore-bearing precloacal and femoral scales on each side (5 vs. 9–11) and a slightly more elongate trunk (TRL/ SVL 0.51–0.55 vs. 0.47–0.51). Hemiphyllodactylus kolliensis sp. nov. differs from Hemiphyllodactylus jnana sp. nov. in having more pore-bearing femoral scales in males (8 vs. 6– 7) and fewer unpored scales separating the pore-bearing precloacal and femoral scales on each side (5 vs. 10–12), fewer dorsals (16 vs. mean 18.3, range 16–20) and fewer ventrals (mean 13.5, range 11–15 vs. 11.3, 10–13). Hemiphyllodactylus kolliensis sp. nov. is compared against Hemiphyllodactylus arakuensis sp. nov. after its descrip- tion. Major diagnostic characters across all Indian Hemiphyllodactylus species are recorded in Table 1 in Agarwal et al. 2019.
