A new freshwater crab is described from the montane area in northeastern Taiwan based on morphological and molecular evidence. Geothelphusa boreas sp. nov., from the Fushan Botanical Garden situated around New Taipei City and Yilan County, is distinct from similar congeners by the structure of the male first gonopod and the proportions of the male thoracic sternites. In addition, after comparing the holotypes of G. takuan and G. hirsuta Tan Liu, 1998, no substantial difference could be found. Molecular evidence from mitochondrial cytochrome oxidase subunit I also supports the recognition of the new species and the conspecificity of G. hirsuta with G. takuan.
一种新的淡水蟹是根据形态和分子证据从台湾东北部的山区描述的。新种北台湾相手蟹（Geothelphusa boreas sp. nov.）来自新北市和宜兰县的福山植物园，其雄性第一生殖肢和雄性胸板的比例与类似的同种动物不同。此外，在比较了 G. takuan 和 G. hirsuta Tan Liu, 1998 的模式标本后，没有发现实质性的差异。来自线粒体细胞色素氧化酶亚单位 I 的分子证据也支持了新物种的识别以及 G. hirsuta 与 G. takuan 的同物异性。
