During deep-sea trawling in Taiwanese waters, four species of galatheids belonging to the genus Munidopsis were collected at two stations deeper than 3000 m. Three species represent new records from Taiwan: M. panamae Baba, 2005, M. profunda Baba, 2005, and M. teretis Baba, 2005, all recently described and known from very limited material. The other is a new species, Munidopsis tafrii, which resembles M. ceratophthalma Alcock, 1901, and M. orcina McArdle, 1901, but clearly differs in characters of the carapace. The specimens of M. profunda from 4430-4455 m are the deepest record for marine animals from Taiwanese waters.
