, a new species from Hunan and Jiangxi, southeastern China, is described. The new species is assigned to the group. The clade comprising and from Anhui is the sister taxon of from Sichuan. can be distinguished by the significant divergences in the 16S and COI genes, and the combination of following morphological characters: body size medium, SVL 48.3-57.8 mm in adult males and 48.2-57.5 mm in adult females; dorsolateral fold straight; digits without circummarginal grooves; dorsal skin smooth; tibio-tarsal articulation reaching forward beyond the tip of snout; heels overlapping; webbing formula of toes: I 1⅓ - 2 II 1⅓ - 2⅓ III 1½ - 2⅔ IV 3 - 1⅓ V; absence of vocal sacs in males; and presence of creamy white nuptial pad with tiny hoar spines on the finger I and reddish tubercles on loreal and temporal regions in breeding males. Furthermore, based on our results and the previous literature, is synonymized with , and a new species group, the group, is proposed for the and . Currently, the Rana contains 41 recognized species, and the phylogenetic placements of several species remain unresolved.
描述了一种来自中国东南部湖南和江西的新物种。该新物种被归入 类群。由来自安徽的 和 组成的分支是来自四川的 的姐妹分类单元。 可通过16S和COI基因的显著差异以及以下形态特征的组合来区分：体型中等，成年雄性的体长为48.3 - 57.8毫米，成年雌性为48.2 - 57.5毫米；背外侧褶直；指无边缘沟；背部皮肤光滑；胫跗关节向前超过吻端；足跟重叠；趾间蹼式：I 1⅓ - 2 II 1⅓ - 2⅓ III 1½ - 2⅔ IV 3 - 1⅓ V；雄性无声囊；繁殖期雄性的第一指上有带微小灰白色刺的乳白色婚垫，以及在吻部和颞部区域有红色瘤。此外，根据我们的结果和先前的文献， 被同义化为 ，并为 和 提出了一个新的物种组，即 组。目前，林蛙属包含41个已确认的物种，并且几个物种的系统发育位置仍未解决。
