It was previously identified as Amolops kangtingensis, which is synonymized to Amolops mantzorum in this study. The new species, Amolops xinduqiao sp. nov., is distinguished from all other congeners by the following combination of characters: (1) medium body size, adult males SVL 41.2-47.5 mm (n=15, average 43.9 mm), adult females SVL 48.5-56.6 mm (n=15, average 52.5 mm); (2) head length equal to width or slightly wider than long; (3) tympanum small, but distinct; (4) vomerine teeth in two tiny rows, separated by a space about one vomerine teeth row; (5) bony projections on lower jaw absent; (6) dorsolateral folds usually absent; (7) tarsal folds or glands on tarsus absent; (8) circummarginal groove on disc of finger I absent; (9) tibiotarsal articulation reaching nostril or beyond; (10) webs of toe IV reaching to distal articulation, other toes fully webbed to disc; and (11) vocal sac absent in males.展开更多

The new species, Amolops nyingchiensis sp. nov. is assigned to the Amolops monticola group based on its skin smooth, dorsolateral fold distinct, lateral side of head black, upper lip stripe white extending to the shoulder. Amolops nyingchiensis sp. nov. is distinguished from all other species of Amolops by the following combination of characters: (1) medium body size, SVL 48.5-58.3 mm in males, and 57.6-70.7 mm in females; (2) tympanum distinct, slightly larger than one third of the eye diameter; (3) a small tooth-like projection on anteromedial edge of mandible; (4) the absence of white spine on dorsal surface of body; (5) the presence of circummarginal groove on all fingers; (6) the presence of vomerine teeth; (7) background coloration of dorsal surface brown, lateral body gray with yellow; (8) the presence of transverse bands on the dorsal limbs; (9) the presence of nuptial pad on the first finger in males; (10) the absence of vocal sac in males. Taxonomic status of the populations that were previously identified to A. monticola from Tibet is also discussed.展开更多
