A new genus and species of freshwater crab, Yuebeipotamon calciatile gen. n., sp. n., is described from southern China. While the carapace features are superficially similar to species of Sinopotamon Bott, 1967, Longpotamon Shih, Huang & Ng, 2016, and Tenuilapotamon Dai, Song, Li, Chen, Wang & Hu, 1984, the new genus possesses a distinctive combination of carapace, ambulatory leg, male thoracic sternal, male abdominal, and gonopodal characters that distinguish it from these and other genera. Molecular evidence derived from the mitochondrial 16S rDNA supports the establishment of a new genus.

在中国南方发现了一种淡水蟹新属新种，即钙质粤北溪蟹（Yuebeipotamon calciatile gen. n., sp. n.）。虽然其背甲特征在表面上与1967年的束腰蟹属（Sinopotamon Bott）、2016年的隆背溪蟹属（Longpotamon Shih, Huang & Ng）和1984年的小肢溪蟹属（Tenuilapotamon Dai, Song, Li, Chen, Wang & Hu）的物种相似，但新属具有独特的背甲、步足、雄性胸腹板、雄性腹部和交接器特征组合，使其有别于这些属和其他属。来自线粒体16S rDNA的分子证据支持新属的建立。
