A new species of freshwater crab, Geothelphusa haituan, is described from the SiangYang National Forest Recreation Area, adjacent to the southeastern part of YuShan National Park in Taiwan. G. haituan is a small-sized Alpine species, obtained at an elevation of about 2000 m a.s.l. The species is diagnosed and figured, and compared with allegedly allied species. Detailed features of the male first gonopod are examined using scanning electron microscopy (SEM), and part of the species COI gene was analysed.
