|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Synonym||Cyrtodactylus septentrionalis AGARWAL, MAHONY, GIRI, CHAITANYA & BAUER 2018|
Type locality: near Abhayapuri town, Bongaigaon district, Assam state, India (26.345417°N, 90.677875°E, 40 m asl)
|Types||Holotype: BNHS 1990, adult female, collected by Varad Giri and Kedar Bhide on 13 November 2009. Paratype. Adult male (BNHS 1989), bears the same collection details as holotype.|
|Diagnosis||Diagnosis. Cyrtodactylus septentrionalis sp. nov. can be distinguished from all congeners by its moderate body size (SVL to at least 65.2 mm); nine or 10 supralabials; nine infralabials; 23 or 24 longitudinal rows of bluntly conical, feebly keeled dorsal tubercles; tubercles extend onto first three tail segments; 38–42 paravertebral tubercles; 35–38 ventral scales between ventrolateral folds; no precloacal groove; 14 fine precloacal pores and no femoral pores on males; 15–20 total subdigital lamellae beneath toe IV of pes; subcaudal scalation of original tail without enlarged plates; dorsal colour pattern of 6–9 rows of paired dark blotches, tail with alternating dark and lighter bands.|
Comparisons. Cyrtodactylus septentrionalis sp. nov. is a member of the lowland clade and differs from other members of the clade by 11.3–18.6 % uncorrected genetic distance. Cyrtodactylus septentrionalis sp. nov. can be diagnosed by the presence of 14 precloacal pores and the absence of femoral pores on males from C. ayeyarwadyensis (10–28 PcP–PcFP), Cyrtodactylus guwahatiensis sp. nov. (26 PcFP in discontinuous series), Cyrtodactylus kazirangaensis sp. nov. (10 or 11 PcP), C. khasiensis (10–12 PcP), and C. tripuraensis (29–37 PcFP). Cyrtodactylus septentrionalis sp. nov. further differs from C. khasiensis in having more dorsal tubercle rows (23 or 24 vs. 19–23). 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 “northern”, as this species is the only known member of the lowland clade (Agarwal et al. 2014) that is found north of the Brahmaputra River, the other five known species of the clade are found south of the Brahmaputra River.|
