Over 110 specimens of xanthid crabs collected from rocky intertidal habitats of Taiwan and its offshore islands during the past 25+ years are examined in the present study. As a result, 24 species are recognized, distributed across seven subfamilies and 16 genera including one new genus record (i.e., Lioxanthodes Calman, 1909) for Taiwan. Of these recognized species, 14 have been previously reported from Taiwan, whereas five are new records for Taiwan, one new to science, and four unnamed species. The five newly recorded species are Chlorodiella barbata (Borradaile, 1900), Etisus frontalis (Dana, 1952), Lioxanthodes alcocki Calman, 1909, and Macromedaeus quinquedentatus (Krauss, 1843), and Pilodius nigrocrinitus Stimpson, 1859. The new species, Cyclodius taiwanensis sp. nov., is herein described.
