Common Names 
SynonymCyrtodactylus nagalandensis AGARWAL, MAHONY, GIRI, CHAITANYA & BAUER 2018 
DistributionIndia (Nagaland)

Type locality: near Khonoma village, Kohima district, Nagaland state, India (25.65818°N, 94.02142°E, 1450 m asl)  
TypesHolotype: BNHS 2253, adult female, field number CES09/1233) collected by Ishan Agarwal on 23 October 2009. Paratype. Adult female (BNHS 2254) bears the same collection information as holotype. 
DiagnosisDiagnosis. Cyrtodactylus nagalandensis sp. nov. can be distinguished from all congeners by its moderate body size (SVL to at least 72.0 mm); 10–12 supralabials; 8–10 infralabials; 16–18 longitudinal rows of rounded, conical, feebly keeled dorsal tubercles; tubercles extending posteriorly to third tail segment; 35–37 paravertebral tubercles; 34 or 35 ventral scales between ventrolateral folds; no precloacal groove; six depressions in precloacal series but no precloacal or femoral pores on females, male condition unknown; 16 total subdigital lamellae beneath toe IV of pes; subcaudal scalation of original tail with paired enlarged subcaudals not forming median plates; dorsal pattern of indistinct light and dark blotches forming longitudinal markings on neck and forebody; tail with alternating dark and lighter bands.

Comparisons. Cyrtodactylus nagalandensis sp. nov. is a member of the mountain clade and is poorly supported as sister to the other Indian species in this clade, with uncorrected p-distance between the new species and other members of the clade 18.0–21.7%. Cyrtodactylus nagalandensis sp. nov. can be diagnosed by the number of ventral scales (36 or 37 MVSR) from C. brevidactylus (45 MVSR), and Cyrtodactylus jaintiaensis sp. nov. (40–42 MVSR); by having fewer dorsal tubercle rows (16–18) from C. gansi (20–25 DTR) and Cyrtodactylus montanus sp. nov. (21–23 DTR); by its irregular dorsal colour pattern from C. chrysopylos (dorsal pattern of alternating brown and white bands). Major diagnostic characters for the new species and regional congeners are summarized in Table 3 (in Agarwal et al. 2018). 
EtymologyThis is the first endemic gecko from Nagaland, and the specific epithet is a toponym for the state.
