Type locality: Lakkidi village (11.5184°N, 76.0451°E; ca. 873 m asl.), Wayanad District, Kerala
|Types||Holotype. BNHS 2340, an adult male, collected by B.H.C.K Murthy and RC on 27th November, 2016.|
Paratypes: Details of collection same as the holotype. BNHS 2341, BNHS 2342, BNHS 2344, ZSIK 2971, ZSIK 2972, ZSIK 2975 adult females; BNHS 2343, ZSIK 2973, ZSIK 2974 adult males.
|Diagnosis||Diagnosis. Snout-vent length up to 56.9 mm (n=10); internasals separated by 2 smaller scales; two pairs of well-developed postmentals, inner pair slightly longer than the outer, briefly in contact with each other behind mental, bordered by mental, infralabial I, outer postmentals and 2 or 3 gular scales. ventral scales counted at midbody, 30–35; precloacofemoral pores, 52–56 (n=4); subdigital lamellae under digit IV of ma- nus, 7–10 and under digit IV of pes, 10–13; supralabials, 8–10 and infralabials, 7–10 on each side.|
Dravidogecko septentrionalis sp. nov., though closely allied to D. anamallensis, can be easily distinguished from the latter by the presence of a greater number of precloacofemoral pores, (PcFP 52–56 versus 45 or 46), a greater num- ber of ventral scales (VS 30–35 versus 25–28) and number of scales between the internasals (two versus one).
|Comment||Genetic divergence (p-distance). Dravidogecko septentrionalis sp. nov. exhibits 0.3% intraspecific variation, and is 5.0–6.5 % divergent from D. anamallensis (Table 9 in Chaitanya et al. 2019).|
Habitat: The type-series of Dravidogecko septentrionalis sp. nov. was collected from outer compound walls of buildings in Lakkidi village in the western part of the Wayanad plateau. The abutting veg- etation is predominantly mid-elevation evergreen forests that get ca. 3500mm–6000mm of annual rainfall (Anu & Sabu 2007). They were found only in areas that were above 850 m asl and seem to be restricted to isolated hillocks with conducive ecological conditions.
|Etymology||The specific epithet is an adjective in the nominative case derived from the Latin for ‘northern’, referring to the distribution of this species to the north of the Palghat Gap.|
