|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Synonym||Cyrtodactylus guwahatiensis AGARWAL, MAHONY, GIRI, CHAITANYA & BAUER 2018|
Type locality: Hengrabari Road, Guwahati City, Kamrup Metropolitan district, Assam state, India (26.16193°N, 91.78298°E, elevation < 100 m asl)
|Types||Holotype: BNHS 2146, adult male, field number CES09/1127), collected by Ishan Agarwal, 11 June 2009.|
|Diagnosis||Diagnosis. Cyrtodactylus guwahatiensis sp. nov. can be distinguished from all congeners by: its moderate body size (SVL up to at least 67.8 mm); 10 supralabials; nine infralabials; 23 or 24 longitudinal rows of bluntly conical, feebly keeled dorsal tubercles; tubercles extending till third segment of tail; 35 paravertebral tubercles; ~34 ventral scales between ventrolateral folds; no precloacal groove; 26 precloacofemoral pores in a discontinuous series interspersed by 11 unpored scales; a row of enlarged scales above and below precloacal pore-bearing scales, slightly larger than pore-bearing scales; 16 total subdigital lamellae beneath toe IV of pes; subcaudal scalation of original tail without enlarged plates; dorsal pattern of 8–10 transverse rows of two or three pale buff blotches outlined by thick dark reticulations. Tail with alternating dark and lighter bands (Agarwal et al. 2018, but see updated diagnosis in Purkayashta et al. 2020: 383).|
Comparisons. Cyrtodactylus guwahatiensis sp. nov. is a member of the lowland clade and is sister to C. septentrionalis sp. nov., the clade also including C. ayeyarwadyensis, C. tripuraensis, C. khasiensis and C. kazirangaensis sp. nov. The p-distance analysis demonstrated that the ND2 gene of the new species is 11.3% divergent from that of C. septentrionalis sp. nov. and 13.0–19.7% divergent from others in the clade (Table 2). Cyrtodactylus guwahatiensis sp. nov. can be diagnosed by the total number of precloacofemoral pores (26 PcFP) on males from C. khasiensis (10–12 PcP) and C. tripuraensis (29–37 PcFP); further differs from C. tripuraensis by having slightly more DTR (23 or 24) and fewer MVSR (34) vs. (19¬21 DTR, 35–43 MVSR). The new species differs in colouration from C. ayeyarwadyensis (no white punctuations or narrow band following dark dorsal markings) Cyrtodactylus guwahatiensis sp. nov. is diagnosed from C. kazirangaensis sp. nov. and C. septentrionalis sp. nov. after the descriptions of the latter two species. Major diagnostic characters for the new species and other regional congeners are summarized in Table 3 (in Agarwal et al. 2018).
