Cyrtodactylus gansi group

Definition and diagnosis. The Cyrtodactylus gansi group ranges from the vicinity of Jowai and Phuldungsei of eastern India, eastward through the Chin Hills of western Myanmar and across the northern section of the Ayeyarwady Basin to the fragmented foothills and upland areas of the western margin of the Shan Plateau ( Fig. 1 ). This monophyletic lineage contains 10 species C. gansi , C. aunglini sp. nov. (description below), C. jaintianensis Agarwal et al. , C. nagalandensis Agarwal et al. , C. montanus Agarwal et al. , Cyrtodactylus sp. Mizoram, C. brevidactylus Bauer , C. myaleiktaung sp. nov. (see description below), and C. chrysopylos Bauer. Cyrtodactylus mandalayensis Mahony is provisionally placed in this group based on its location from the vicinity of Mogok, Mandalay Region approximately 100 km north of Kyauk Nagar Cave along the western margin of the Shan Plateau and its superficial similarity to C. aunglini ( Mahony 2009; Table 3). Confirmation of the placement of this species in the gansi group awaits molecular phylogenetic evidence. The gansi group is diagnosed by having the unique combination of the following characters: maximum SVL of 59.0– 96.2 mm; 7–12 supralabials; 8–11 infralabials; 30–53 paravertebral tubercles; 16–30 rows of longitudinal tubercles; 21–57 ventral scales; 10–29 subdigital lamellae on the fourth toe; no enlarged femoral scales; no pore-bearing femoral scales; 8–29, enlarged, contiguous, pore-bearing, precloacal scales in males; 2–7 cloacal spurs; no plate-like subcaudal scales; light caudal bands not encircling the tail; 7–15 light caudal bands; and 7–15 dark caudal bands ( Table 3).
