A new galatheid genus, Raymunida, is established for two known species, Munida elegantissima de Man, 1902, and M. bellior Miyake and Saba, 1967, and one new species, R. cagnetei from the Marquesas Islands (French Polynesia, Pacific Ocean). This new genus is easily distinguished from the genus Munida Leach, 1820, and other galatheid genera by the following combination of characters: (I) the presence of epipods on first, second, and third pereiopods; (2) one spine on the frontal margin between supraocular and anterolateral spines; (3) one distal spine on the flexor margin of the carpus of the third 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 setae on the carapace and abdomen, the length of the propodus of the walking legs, and the number of striae on the abdominal somites.
