摘要

淡水蟹的身份，Aiyunamon tumidum (Wood-Mason, 1871)，在类型重新检查后澄清。该类型系列是混合的，包括两个物种的标本。云南庞泽的一个总型被指定为本种的选型;来自云南和他的现在被称为A. daiae (Zhang & Sun, in Zhang, Pan, Hao & Sun, 2020)。以前被称为“A。云南其他地区的tumidum在这里被鉴定为一个新种，Aiyunamon fatum sp. nov。通过雄性第一性腺的结构，可以很容易地将其与同类区分开来。

The identity of the freshwater crab Aiyunamon tumidum (Wood-Mason, 1871) (Brachyura, Potamidae), with description of a new species from China

The identity of the freshwater crab, Aiyunamon tumidum (Wood-Mason, 1871), is clarified after the types are re-examined. The type series is mixed and includes specimens of two species. A syntype from Ponsee in Yunnan, P.R. China, is designated the lectotype of the species; those from Hotha in Yunnan are now referred to A. daiae (Zhang & Sun, in Zhang, Pan, Hao & Sun, 2020). Specimens which have previously been referred to as “A. tumidum” from other parts of Yunnan are here identified as a new species, Aiyunamon fatum sp. nov.. Aiyunamon fatum is most easily distinguished from congeners by the structure of the male first gonopod.
