Type locality: “near Kodalagurki village, Bangalore rural district, Karnataka, India (13.297508°N, 77.700259°E), elevation 950 m”  
TypesHolotype: NCBS AU712, female, collected by Mayuresh Ambekar & Gaurang Gowande on November 20th, 2017. Paratypes: NCBS AU713, female, same locality as holotype, collected by Rishikesh Patil and Zeeshan Mirza; two males NCBS AU719 & AU720, GKVK campus, Bangalore Karnataka, India (13.072962N, 77.581215E, elevation 932 m), collected by Akshay Khandekar on April 16th, 2018. 
DiagnosisDiagnosis: A medium sized fairly stout gecko, adults ranging 45–60 mm in SVL. Dorsum in a shade of light brown with paired, thin black edged white bands at regular intervals. Dorsal scalation on trunk granular, intermixed with enlarged, keeled 16–17 sub-trihedral tubercle rows arranged in fairly regular longitudinal series on dorsum. Seven lamellae (rarely six) under digit I of pes and manus, eight to nine under digit four of manus and pes. An angular series of seven to eight precloacal femoral pores separated at a mid-pelvic by a diastema of three non-pored scales.

Hemidactylus whitakeri sp. nov. differs from most congeners in bearing the following set of differing and non-overlapping characters: dorsum with large, keeled sub-trihedral tubercles in 16–17 fairly regular longitudinal rows (vs. few smooth or rounded tubercles in H. aquilonius McMahan & Zug, H. flaviviridis Rüppell, H. frenatus Schlegel, H. garnotii Duméril & Bibron, H. leschenaultii Duméril & Bibron, H. giganteus Stoliczka, H. gujaratensis Giri, Bauer, Vyas & Patil, H. platyurus Schneider, H. anamallensis Günther, H. aaronbaueri Giri, H. yajurvedi Murthy, Bauer, Lajmi, Agarwal & Giri, H. hemchandrai Dandge & Tiple); dorsal pattern with fairly distinct bands and dorsal tubercles sub- trihedral (vs. dorsal pattern with spots in H. prashadi); SVL 45–60 mm (vs. SVL <50 mm in H. sataraensis Giri & Bauer, H. gracilis Blanford, H. reticulatus Beddome, H. albofasciatus Grandison & Soman, H. scabriceps Annandale); SVL >80 mm H. maculatus Duméril & Bibron, H. graniticolus Agarwal, Bauer & Giri, H. kangerensis, H. sushilduttai, H. vanam Chaitanya, Lajmi & Giri, H. acanthopholis Mirza & Sanap, and H. hunae Deraniyagala; dorsum in a shade of brown with distinct, regularly spaced transverse bands on dorsum (vs. overall in a shade of brown to grey with dark spots, lacking distinct bands on dorsum in H. persicus Anderson, H. robustus Heyden, H. turcicus Linnaeus, H. chipkali Mirza & Raju, H. treutleri Mahony, H. gleadowi Murray, H. parvimaculatus Deraniyagala, H. kushmorensis Murray, H. murrayi Gleadow, H. malcolmsmithi Constable). The new species is most similar to H. triedrus in general appearance, however, differs in bearing 16–17 rows of keeled, sub-trihedral tubercles in fairly longitudinal rows (vs. 19–20 keeled, trihedral tubercles in H. triedrus, 15–16 trihedral tubercles in H. sahgali sp. nov.), bands on dorsum thin, paired and usually broken incomplete (vs. bands complete in H. sahgali sp. nov.), 7–8 precloacal femoral pores separated by a diastema of three non-pored scales (vs. 11–15 precloacal femoral pores separated by a diastema of 1–3 non-pored scales in H. sahgali sp. nov.). Postorbitofrontal slender in anteriorly, gradually widens posterior to the Fronto-Parietal suture as seen in H. sahgali sp. nov. (vs. Postorbitofrontal uniform in its wide throughout in H. triedrus), Frontal much wider posteriorly as in H. sahgali sp. nov. (vs. frontal narrow in H. triedrus); quadrate bone moderately robust (vs. quadrate bone robust and thin in H. triedrus, slender and arched in H. sahgali sp. nov.), surangular slender as in H. triedrus (vs. robust in its width lacking a distinct constriction at the suture between—articular surface and retroarticular process).
