DiagnosisDiagnosis. Cnemaspis tarutaoensis sp. nov. can be distinguished from all other Cnemaspis by having the following combination of characters: (1) adult males with maximum snout-vent length (SVL) 36.4 mm (mean 34.7 ± SD 1.5, n = 7) and females with maximum SVL 34.8 mm (mean 33.7 ± SD 0.6, n = 6); (2) 8–9 supralabials and 8 infralabials; (3) 4–5 pore-bearing precloacal scales, pores rounded; (4) 17–19 paravertebral tubercles, small in size, randomly arranged; (5) 27–29 subdigital lamellae under the 4th toe; (6) subcaudal region yellowish, scales smooth with a single enlarged median subcaudal row; (7) one postcloacal tubercles on each side; (8) no sexual dimorphism in dorsal and ventral patterns; and (9) black gular markings present in males and females. These differences are summarized for geographically close congeners in the kumpoli group (Table 4 in Ampai et a. 2019).

Comparisons. Cnemaspis tarutaoensis sp. nov. can be distinguished from all other members of the kumpoli group (C. biocellata, C. kumpoli, C. monachorum, and C. niyomwanae) by having a maximum SVL of 36.4 mm (vs 32.9 mm in C. monachorum, 40.2 mm in C. biocellata, 63.0 mm in C. kumpoli, and 56.8 mm in C. niyomwanae).
Cnemaspis tarutaoensis sp. nov. is further distinguished from C. monachorum by having eight infralabial scales (vs 5–7 in C. monachorum). The new species is further distinguished from C. biocellata, C. monachorum and C. niyomwanae by having 4–5 precloacal pores (vs 6–12 in C. biocellata and three in C. monachorum and C. niyomwanae). The new species is further distinguished from C. biocellata, C. kumpoli, and C. niyomwanae by having 17–19 paravertebral tubercles (vs 21–27 in C. biocellata, 28–35 in C. kumpoli and 26–31 in C. niyomwanae). The new species is further distinguished from C. biocellata and C. kumpoli by lacking tubercles on lower flanks (vs present in C. biocellata and C. kumpoli). The new species is further distinguished from C. biocellata, C. kumpoli and C. niyomwanae by having 26–29 lamellae under the 4th toe (vs 29–37 in C. biocellata, 34–41 in C. kumpoli, and 31–34 in C. niyomwanae).
Cnemaspis tarutaoensis sp. nov. is further distinguished from C. kumpoli, C. monachorum and C. niyomwanae by having yellow coloration in the subcaudal region and wide black and yellow bands on tail (vs lacking in C. kumpoli, C. monachorum, and C. niyomwanae). The new species is further distinguished from C. biocellata, C. kumpoli, and C. niyomwanae by lacking a sexually dimorphic dorsal color pattern (vs present in C. biocellata, C. kumpoli, and C. niyomwanae). The new species is further distinguished from C. monachorum and C. biocellata by lacking lateral caudal tubercle row (vs present in C. monachorum and C. biocellata). The new species is distinguished from C. biocellata, C. kumpoli, and C. niyomwanae by having gular marking (vs lacking in C. biocellata, C. kumpoli, and C. niyomwanae).
