A new species of the genus Nidirana Dubois, 1992 (Anura: Ranidae) from Yunnan Province, China

A new species of the genus Nidirana Dubois, 1992 is described from Cangshan Mountain, Dali Prefecture, Yunnan Province, China. The new species is morphologically most similar to N. pleuraden (Boulenger, 1904) and N. occidentalis Lyu, Yang & Wang, 2020, but it can be distinct from the latter two species by having a relatively shorter and wider head, relatively larger eyes, relatively smaller tympana, relatively much shorter foot, and a much greater difference in body size between males and females. Phylogenetically, the new species differs from its congeners by a genetic divergence of 2.6–8.6% and 6.1–14.1% in 16S and COI genes, respectively. This study further emphasizes that the diversity of the genus Nidirana is still severely underestimated.
