摘要

对包含 7 个种的淡水蟹属 Tenuipotamon Dai（1990 年）的分类进行了修订。根据同时进行的分子系统发育研究，Tenuipotamon 属为副系，由两个系组成。在本研究中，严格意义上的 Tenuipotamon 仅限于其模式种 T. purpura Dai，1990 年，同时建立了一个新属 Pusillamongen、baisuiense Chen, 1993, T. huaningense Dai & Bo, 1994, T. panxiense Chen, 1993, T. tonghaiense Chen, 1993, T. xinpingense Chen, 1993, and T. yuxiense Chen, 1993）。这两个属都是中国西南部地形复杂的横断山区的特有种，本文对它们进行了诊断。

Revision of the Chinese freshwater crab genus Tenuipotamon Dai, 1990 (Decapoda: Brachyura: Potamidae), with the description of a new genus from southwestern China

The taxonomy of the potamiscine freshwater crab genus Tenuipotamon Dai, 1990, which contains seven species, is revised. According to a concurrent molecular phylogenetic study, Tenuipotamon is paraphyletic, and is composed of two lineages. In this study, Tenuipotamon sensu stricto is restricted to its type species, T. purpura Dai, 1990, while a new genus, Pusillamongen. nov., is established to accommodate the remaining six species placed previously in Tenuipotamon sensu stricto (T. baishuiense Chen, 1993, T. huaningense Dai & Bo, 1994, T. panxiense Chen, 1993, T. tonghaiense Chen, 1993, T. xinpingense Chen, 1993, and T. yuxiense Chen, 1993). Diagnoses are provided for the two genera, which are both endemic to the topographically complex Hengduan Mountains Region of southwestern China.
