Raymunida, new genus (Decapoda : Anomura : Galatheidae) from the Indian and Pacific Oceans

A new galatheid genus, Raymunida, is established for two known species, Mun ida elegantissima de Man, 1902, and M, bellior Miyake and Baba, 1967, and o ne new species, R. cagnetei from the Marquesas Islands (French Polynesia, P acific Ocean). This new genus is easily distinguished from the genus Munida Leach, 1820, and other galatheid genera by the following combination of ch aracters: (1) the presence of epipods on first, second, and third pereiopod s; (2) one spine on the frontal margin between supraocular and anterolatera l spines; (3) one distal spine on the flexor margin of the carpus of the th ird maxilliped; (4) the merus of the second pereiopod clearly more slender than those of third and fourth pereiopods; and (5) the presence of several long marginal spines on the endopod of the uropods. Raymunida cagnetei, new species and type species of the genus, is clearly distinguishable from the other species of the genus by the colour pattern, the presence of long set ae on the carapace and abdomen, the length of the propodus of the walking l egs, and the number of striae on the abdominal somites.
