A new species of the Amolops monticola group (Anura, Ranidae) from southern Yunnan, China

A new species of the Amolops monticola group is described from Yunnan Huanglianshan National Nature Reserve, southern Yunnan, China. Morphologically, the new species is characterized by a moderate body size (snout–vent length 38.3–40.8 mm in adult males and 62.3–63.1 mm in adult females), head being longer than wide, nostril to snout tip distance being slightly smaller than eye to nostril distance, the presence of pineal body, distinct tympanum, vomerine teeth being invisible in males and weak but visible in females, distinct dorsolateral folds, the absence of outer metatarsal tubercle, the presence of vocal sac and nuptial pad in adult males, dorsal surface of head and body being green with no or a few black dots, and the presence of a few large flat white tubercles on the posterior inferior flank. Genetically, the uncorrected genetic distance between the new species and other species of the A. monticola group ranged from 3.0% to 7.6% in 16S ribosomal RNA and from 7.2% to 17.1% in NADH dehydrogenase subunit 2 gene sequences. Currently, the new species is known only from its type locality in Lvchun County, Honghe Prefecture, Yunnan Province, China.
