|Diagnosis||Diagnosis and comparison against regional congeners. A moderate sized Cyrtodactylus, snout-vent length to 70.7 mm; body and limbs relatively slender, digits short; one pair of enlarged postmental scales in broad contact behind mental; 19–21 rows of circular tubercles at mid-dorsum, bluntly conical and weakly keeled throughout; 44– 54 paravertebral tubercles; 35–43 mid-body ventral scale rows; no precloacal groove; males with 29–37 precloacofemoral pores in a single series, females with 19–29 pitted/pored scales. Four to nine basal and 11–16 apical subdigital lamellae beneath Digit IV of pes with one or two intervening rows of non-lamellar granular scales between basal and distal lamellae series. Subcaudals larger than dorsal tail scales, not in an enlarged median series (on original tail). Dorsal pattern of 7–10 paired transversely arranged dark spots that may be irregular and broken up, occasionally alternating with lighter spots. Original tail with 11–13 alternating dark and light bands, last few light bands almost white.|
Cyrtodactylus tripuraensis sp. nov. differs from the following species by the presence of a continuous series of precloacofemoral pores (vs. precloacal pores separated from femoral pores by a diastema of multiple poreless scales): C. annandalei, Cyrtodactylus bhupathyi sp. nov., C. fasciolatum, C. gubernatoris, C. russelli, and C. slowinskii. The large number of precloacofemoral pores on males of the new species (29–37) separates it from C. brevidactylus (8 PcP), C. cayuensis (6–9 PcP), Cyrtodactylus himalayicus comb. nov. (10 PcP), C. khasiensis (10– 12 PcP), C. mandalayensis (8 PcP + single enlarged pore-bearing scale at the posterior apex of PcP), C. markuscombaii (7 PcP), C. martinstolli (0–8 PcP), and C. wakeorum (12 PcP). Cyrtodactylus tripuraensis sp. nov. differs from C. tamaiensis by having slightly fewer precloacofemoral pores (29–37 vs. 40), male body size (SVL 55.4–65.0 mm vs. 90.0 mm), longer trunk (TrL/SVL mean 0.49, range 0.46–0.52 vs. 0.41) and dorsal pattern (8–10 irregular paired dark spots vs. irregular dark and light reticulations), and from C. gansi in the absence of a precloacal groove (vs. presence of precloacal groove on males). Cyrtodactylus tripuraensis sp. nov. is most similar to C. ayeyarwadyensis from which it differs by a slightly higher number of precloacofemoral pores on males (29– 37 vs. 10–28), the presence of pores in females (vs. absence of pores), and fewer dorsal tubercle rows (19–21 vs. 22–24). Cyrtodactylus tripuraensis sp. nov. differs from C. ayeyarwadyensis sensu lato (Mahony et al. 2009a) by the presence of precloacofemoral pores on females (vs. absence of pores).
|Comment||Habitat: <1.5 m from the ground and mainly from muddy road cuts in secondary and degraded moist deciduous forest; the individual from Rowa was on the trunk of a coppiced tree and one from Gumti was found under a rock in a hill forest approximately 10 m from the road.|
|Etymology||The species epithet is a toponym for Tripura, the Indian state in which all currently known populations are found.|
