|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Synonym||Cyrtodactylus montanus AGARWAL, MAHONY, GIRI, CHAITANYA & BAUER 2018|
|Distribution||India (Tripura, Mizoram)|
Type locality: near Phuldungsei village in the southern Jampui Hills, Kanchanpur subdivision, North Tripura district, Tripura state, India (23.82257°N, 92.26034°E, 850 m asl)
|Types||Holotype: BNHS 2235, adult female, field number CES09/1215), collected by Tarun Khichi, N.P.I. Das, Aniruddha Datta-Roy and Ishan Agarwal on 3 November 2010. Paratypes. Adult males (BNHS 2232–2234) and an adult female (BNHS 2231), bear the same collection data as the holotype.|
|Diagnosis||Diagnosis. Cyrtodactylus montanus sp. nov. can be distinguished from all congeners by its moderate body size (SVL to at least 78.2 mm); eight or 10 supralabials; 8–10 infralabials; 21–23 longitudinal rows of rounded, conical, feebly keeled dorsal tubercles; tubercles extending posteriorly to at least third tail segment; 37–43 paravertebral tubercles; 21–23 ventral scales between ventrolateral folds; no precloacal groove; 8–10 precloacal pores in males, no femoral pores; a row of enlarged scales posterior to precloacal pore-bearing scales, slightly larger than pore- bearing scales; 13–18 total subdigital lamellae beneath toe IV of pes; subcaudal scalation lacking enlarged median plates; dorsal colour pattern of thick dark reticulations enclosing lighter blotches; tail with alternating dark and lighter bands.|
Comparisons. Cyrtodactylus montanus sp. nov. is a member of the mountain clade and is sister to C. sp. Mizoram from which it differs by 10.1% uncorrected ND2 p-distance, separated from other members of the clade by p-distance of 19.0–21.5%. Cyrtodactylus montanus sp. nov. can be diagnosed by the presence of 8–10 precloacal pores in a single series (or separated medially by a single scale) in males only from C. gansi (16–29 PcFP) and Cyrtodactylus jaintiaensis sp. nov. (11–12 PcP on both males and females), also distinguished from the latter by its slightly smaller size (SVL up to 78.2 mm vs. up to 96.2 mm); and by the number of dorsal tubercle rows (21–23) from C. brevidactylus (27 DTR) and C. chrysopylos (16 DTR). Cyrtodactylus montanus sp. nov. is distinguished from Cyrtodactylus nagalandensis sp. nov. after its description. Major diagnostic characters for the new species and regional congeners are summarized in Table 3 (in Agarwal et al. 2018).
|Etymology||The specific epithet is a nominative, masculine, singular, Latin adjective meaning “pertaining to a mountain” as this species is a member of the mountain clade, and is restricted to a mountainous region in northwestern Tripura.|
