A new species of Amolops (Anura: Ranidae) from northern Myanmar

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.
