|female Holotype Xenophrys jinggangensis Wang 2012|
A new species, Xenophrys jinggangensis sp. nov., is described based on a series of specimens collected from Mount Jinggang, Jiangxi Province, Eastern China. The new species can be easily distinguished from other known congeners by morphology, morphometrics and molecular data of the mitochondrial 16SrRNA gene. The new species is characterized by its small size with adult females measuring 38.4–41.6 mm in snout-vent length and males measuring 35.1–36.7 mm; head length approximately equal to head width; tympanum large and distinct, about 0.8 times of eye diameter; vomerine teeth on two weak ridges; tongue not notched behind; relative finger length II < I < IV < III; slight lateral fringes present on digits; toes bases with thick, fleshy web; dorsum with tubercles and swollen dorsolateral folds; large pustules scattered on flanks; and unique color patterns. The new species represents the thirty-first known Xenophrys in China.

Distribution and biological ecology. Currently, X. jinggangensis sp. nov. is known only from the type locality, Mount Jinggang, located in the middle of the Luoxiao Range, running along the border between Jiangxi and Hunan Provinces, China. All individuals were found in small, slow-moving montane streams surrounded by moist subtropical evergreen broadleaved forests between 700–850 m elevations (Figure 1, 5).
Etymology. The specific epithet “jinggangensis” is in reference to the type locality, Mount Jinggang, Jiangxi Province, China.
