sp. n. from Maolan National Nature Reserve, Guizhou, southwest China, is described. sp. n. has diagnostic features of , such as a slender and sinuous male first gonopod, prominently convex carapace, and one-third ratio of frons to carapace width. This new species can be distinguished from congeners by the combination of the following characters: relatively slender subterminal segment of the first gonopods, nearly oval-shaped carapace, anterolateral margin cristate of carapace and an oval-shaped gap between the fingers of the male major chela. In addition, we used a 16S rRNA gene fragment to explore the relationship between sp. n. and , and other freshwater crabs distributed in Guizhou; the results support the new species being assigned to and clearly different from other species used in the analysis.
描述了来自中国西南部贵州茂兰国家级自然保护区的一个新物种。该新物种具有[属名]的诊断特征，例如雄性第一触角细长且弯曲、头胸甲显著凸起，以及额宽与头胸甲宽度之比为三分之一。这个新物种可通过以下特征组合与同属其他物种区分开来：第一触角亚末端节相对细长、头胸甲近乎椭圆形、头胸甲前侧缘具嵴，以及雄性大螯指节间有椭圆形间隙。此外，我们使用16S rRNA基因片段来探究该新物种与[属名]以及贵州分布的其他淡水蟹之间的关系；结果支持将该新物种归入[属名]，且明显不同于分析中使用的其他物种。
