Type locality: Amboli (15.960 N, 73.999 E; 735 m elevation), Sindhudurg district, Maharashtra, India
|Reproduction||oviparous; Sayyed et al. have observed gravid females in the months of September and October|

Paratypes: BNHS 2459 (adult female), BNHS 2504, BNHS 2506, BNHS 2507, BNHS 2508, and BNHS 2505 (all male) have the same collection data as for the holo- type, collected on tree trunks, rocks, inside walls of local houses, and on stone compound walls.|
|Diagnosis||Diagnosis: Medium-sized day gecko, SVL less than 32 mm; dorsal scales on trunk heterogeneous; granular, keeled, small scales intermixed with some large keeled scales; some conical and spine-like tubercles on flank; ventral scales smooth, imbricate, larger than dorsal; 19–22 midbody scales across the belly; scales on snout feebly keeled; canthus rostralis and forehead granular, feebly keeled; rostral not swollen, medial groove absent; gular with carinate scales, anterior gular scales smooth; dorsal scales on forelimb and hindlimb tricarinate; tail sub-cylindrical, ventrally swollen, one small triangular post-anal spur along each side present in males; sub-caudal smooth, imbricate, second and third rows each side carinated, median row slightly enlarged; 6–7 lamellae on digit I of manus and 10 on digit IV, 6–7 on digit I of pes and 10–11 on digit IV; males with three or four pre-anal pores and 3–4 femoral pores on each side of thigh.|
Remarks: Cnemaspis amboliensis is distinguished from C. goaensis by having a maximum SVL 32 mm (vs. less than 28.3 mm); rostral scale not divided, medial groove absent (vs. rostral scale partially divided by a medial groove); nares separated by two supranasals, of the three internasal scales, middle one extends towards snout tip (vs. nares separated by two enlarged supranasals, a single internasal); primary postmental scale separated by men- tal scale (vs. primary postmental scale separated by sin- gle gular scale); scales on ventral surface of neck smooth (vs. scales on ventral surface of neck feebly carinate); dorsal scales on forelimb and hindlimb tricarinate (vs. dorsal scales on both fore and hindlimb weakly carinate) (Table 6).
Comparison: Cnemaspis amboliensis may be distin- guished from all other peninsular Indian congeners on the basis of the following differing or non-overlapping characters: dorsal scales on trunk heterogeneous (vs. dorsal scales homogenous in C. adii, C. boiei, C. indi- ca, C. indraneildasii, C. jerdonii, C. kolhapurensis, C. littoralis, C. mysoriensis, C. nilagirica, C. sisparensis, and C. wynadensis); males with pre-anal and femoral pores (vs. males with femoral pores in C. flaviventralis, C. girii, C. heteropholis, and C. kottiyoorensis; no pre- anal or femoral pores in C. assamensis; two pre-anal pores present which is separated by two unpored scales, 3–5 femoral pores on each side in C. gracilis; femoral pores absent whereas pre-anal pores present in C. nairi); spine-like tubercles present on flanks (vs. spine like tu- bercles absent on flanks in C. anaikattiensis, C. australis, C. beddomei, C. ornate, C. otai, and C. yercaudensis); sub-caudal slightly enlarged and smooth; rostral medial groove absent (vs. no median series of enlarged sub-cau- dals; rostral medial groove present in C. flaviventralis; sub-caudals enlarged, keeled intermixed with smooth, carinate scales; rostral scale partially divided by a me- dial groove in C. monticola; no median series of enlarged sub-caudals in C. andersonii); males with three or four pre-anal pores and 3–4 femoral pores on each side of the thigh; dorsal scales on forelimb and hindlimbs tricari- nate, (vs. four pre-anal pores, four or five femoral pores on each side; dorsal scales on both fore and hind limbs smooth in C. wicksi); ventral scales smooth, imbricate; 19–22 midventrals (vs. ventral scales of the body keeled and imbricate; 28 midventrals in C. tropidogaster); from Cnemaspis limayei sp. nov. and Cnemaspis ajijae sp. nov. by having conical and spine-like tubercles on flank; presence of pre-anal pores; 19–22 midventrals (vs. coni- cal and spine-like tubercles absent; pre-anal pores absent in both species; 26–27 midventrals in Cnemaspis limayei sp. nov., 29–30 in Cnemaspis ajijae sp. nov.). New spe- cies is similar in size and general appearance to Cnemas- pis goaensis, however differs from this by rostral scale not divided, medial groove absent (Fig. 18a and 19a) (vs. rostral scale partially divided by a medial groove (Fig. 19b)); nares separated by two supranasals, of the three internasal scales, middle one extends towards snout tip (vs. nares separated by two enlarged supranasals, single internasal); primary postmental scale separated by men- tal scale (vs. primary postmental scale separated by sin- gle gular scale); scales on ventral surface of neck smooth (vs. scales on ventral surface of neck feebly carinate); granular keeled small scales intermixed with some large keeled scales dorsally; neck and sacrum with feebly keeled scales (vs. mid-dorsal granules, mixed with large keeled tubercles from head to sacrum); dorsal scales on forelimb and hindlimb tricarinate (Fig. 17a, b, and 20 a, c) (vs. dorsal scales on both fore and hindlimb weakly carinate (Fig. 20b, d)); lamellae manus 7–8–11–10–9, pes 7–9–11–11–10, measurement of right fingers: fourth finger larger than third, third larger than second, second larger than fifth, and fifth larger than first; toes: fourth larger than fifth, fifth larger than third, third larger than second, and second larger than first (vs. lamellae manus 9–12–13–15–11, pes 9–12–16–16–16; measurement of right fingers: fourth finger equal to second, third smaller than fourth and second, fifth smaller than third, and first smaller than fifth; toes: second larger than first, first larger than third, third larger than fourth, and fourth larger than fifth); sub-caudal smooth, imbricate, median row slightly enlarged, second and third rows each side carinated (Fig. 18d and 21c) (vs. median row of subcaudals slightly en- larged, smooth (Fig. 21d)); prominent acuminate keeled tubercles present with small keeled scales on dorsal tail (Fig. 18b and 21a) (vs. dorsal scales on mid-tail acute, imbricate, carinate (Fig. 21b)).
