Nine species hermit crabs of the genus Dardanus are collected in Taiwan. They are Dardanus lagopodes (Forskal, 1775), D. arrosor (Herbst, 1796), D. megistos (Herbst, 1804), D. guttatus (Olivier, 1811), D. crassimanus (H. Milne Edwards, 1836), D. aspersus (Berthold, 1846), D. gemmatus (H. Milne Edwards, 1848), D. pedunculatus (Herbst, 1848) and D. impressus (De Haan, 1849). For D. haani (Rathbun, 1902), D. euopsis (Dana, 1852) and D. diogenes (De Haan, 1849), they were previously reported from Taiwan under the synonymies of D. pedunculatus, D. aspersus and D. lagopodes respectively. The occurence of D. gemmantus is a new addition to the marine fauna list of Taiwan. These species can be found at littoral areas and within the by-cathes of shrimp trawlers around Taiwan. The color plates and a key are provided for their easy identification.
