Abstract
A new species of the genus Amolops, Amolops putaoensis sp. nov., is described from northern Myanmar. The new species can be distinguished from its congeners by the following characters: (1) dorsolateral fold distinct; (2) upper-lip stripe white; (3) male body size 37.6-40.2 mm; (4) ground color of dorsal surface brown, flank green, small warts on dorsum; (5) two internal subgular vocal sacs present; (6) HL slightly shorter than HW; (7) two palmar tubercles present, supernumerary tubercles and outer metatarsal tubercle absent; (8) tympanum smaller than half of eye diameter; (9) vomerine teeth present; (10) tibiotarsal articulation reaching beyond snout tip; (11) supratympanic fold indistinct; (12) pineal body present; (13) finger webbing absent, presence of circummarginal groove on tip of first finger; (14) nuptial pads present. The population from Myanmar represented a distinct maternal lineage within the Amolops monticola group and was recovered as a sister taxon to Amolops aniqiaoensis with strong support (100) based on concatenated data. Average uncorrected pairwise distances ( P-distances) between the specimens from Myanmar and other species in the genus ranged from 2.69% (vs. A. aniqiaoensis) to 12.24% (vs. A. indoburmanensis) for 16S rRNA, 6.14% (vs. A. aniqiaoensis) to 15.79% (vs. A. panhai) for COI, and 9.66% (vs. A. aniqiaoensis) to 19.52% (vs. A. afghanus) for ND2.

Amolops putaoensis sp. nov.
Diagnosis: Morphologically, Amolops putaoensis sp. nov. can be distinguished from its congeners by a combination of the following characters: (1) dorsal skin smooth; (2) dorsolateral fold distinct; (3) head side dark with light-colored upper lip stripe extending to axilla; (4) finger webbing absent, presence of circummarginal groove on tip of first finger; (5) body size of males 37.6–40.2 mm; (6) ground color of dorsal surface brown, flank green, small warts on dorsum; (7) two internal subgular vocal sacs present; (8) two inner palmar tubercles present, supernumerary tubercles and outer metatarsal tubercle absent; (9) tooth-like apophysis on anterior part of lower jaw absent; (10) “/ \”-shaped mark on chest absent; (11) HL slightly shorter than HW; (12) tympanum smaller than half of eye diameter; (13) vomerine teeth present; (14) tibiotarsal articulation reaching beyond snout tip; (15) supratympanic fold indistinct; (16) pineal body present; and (17) nuptial pads present.
Distribution and ecology: The new species is known only from Kachin State, Northern Myanmar. The holotype was found sitting on a branch (ca. 0.5 m above the ground) of a withered tree near the bank of a fast-flowing stream. No tadpoles or vocal recordings were collected for the new species.
Etymology: The specific epithet is named for Putao Township, where the type locality is located. We suggest the English common name as “Putao Cascade Frog” and the Chinese common name as “葡萄湍蛙”.
