A new genus and new species of terrestrial freshwater crab, Calcipotamon puglabrum gen. nov. et sp. nov., is described from the limestone forests of Changjiang, Hainan Island, China, based on morphology and mitochondrial 16S rDNA sequences. The new genus is closest to Neotiwaripotamon Dai Naiyanetr, 1994, and Tiwaripotamon Bott, 1970, but differs in a combination of carapace, third maxilliped, ambulatory leg and male gonopod characters. Molecular analysis shows that the new genus is closely related with but not clustered within other Hainan potamid genera. Notes on the general biology of this new species are also provided.
基于形态学和线粒体16S rDNA序列，在中国海南岛昌江的石灰岩森林中描述了一种新的陆生淡水蟹属及新物种——秀丽钙螯蟹（Calcipotamon puglabrum gen. nov. et sp. nov.）。该新属与1994年的新仿束腹蟹属（Neotiwaripotamon Dai Naiyanetr）和1970年的束腹蟹属（Tiwaripotamon Bott）最为接近，但在头胸甲、第三颚足、步足和雄性生殖肢特征组合上有所不同。分子分析表明，该新属与海南其他束腹蟹属关系密切，但未聚类于其中。还提供了关于这个新物种一般生物学的注释。
