Resurrection of genus Nidirana (Anura: Ranidae) and synonymizing N. caldwelli with N. adenopleura, with description of a new species from China. Supplementary Table S1

The taxonomy of Babina sensu lato was controversial in the past decades. In this study, the phylogeny of genus Babina sensu lato was re-constructed based on genetic analysis, morphological comparison and advertisement call analysis. We found that Babina sensu stricto and previous subgenus Nidirana should be two distinct genera in the family Ranidae. N. caldwelli is confirmed to be a synonym of N. adenopleura because of the small genetic divergence and the lack of distinct morphological differences. A new species, Nidirana nankunensis sp. nov. is described based on a series of specimens collected from Mt. Nankun, Guangdong Province, China, which can be distinguished from other known congeners by having a behavior of nest construction, distinctive advertisement calls, significant divergence in the mitochondrial genes, and a combination of morphological characters. Currently, the genus Babina contains two species and the genus Nidirana contains eight species.

过去数十年来，广义Babina属（Babina sensu lato）的分类学系统一直存在争议。本研究通过遗传分析、形态学比较以及鸣唱声分析，重新构建了广义Babina属的系统发育关系。研究发现，狭义Babina属（Babina sensu stricto）与此前的Nidirana亚属，应当隶属于蛙科（Ranidae）下的两个独立属。鉴于二者遗传分化程度极低且无显著形态差异，N. caldwelli被确定为N. adenopleura的同物异名。本研究基于采自中国广东省南昆山的一系列标本，描述了一新种Nidirana nankunensis sp. nov.，该新种可通过筑巢行为、独特的鸣唱声、线粒体基因的显著分化以及一系列形态特征组合，与其他已知同属物种相区分。目前，Babina属仅包含2个物种，Nidirana属则包含8个物种。
