Species of Galacantha and Munidopsis (Crustacea: Decapoda: Anomura: Galatheidae) from the deep-waters off Taiwan, with the description of two new species

摘要

One species of the genus Galacantha A. Milne-Edwards, 1880, and 20 species of Munidopsis Whiteaves, 1874, including two new species, are reported from the deep-waters off Taiwan. Munidopsis echinata n. sp. closely resembles M. colombiana Pequegnat andPequegnat, 1971 from the Caribbean Sea, but differs in lacking an antennal spine on the carapace and having a much longer antennal peduncle. Munidopsis tuberosa n. sp. appears close to M. granosicorium Williams and Baba, 1990 from the northeast Pacific,but the configuration of the carapace and rostrum separates these two species. Altogether 31 species of Munidopsis are now recorded from Taiwan, indicating a particularly rich deep-sea fauna of the island.
