Remarks on the genus Intesius (Crustacea, Decapoda, Brachyura, Goneplacidae) and description of two new species

After a discussion of the valid publication date of the genus Intesius Guinot & Richer de Forges, 1981 and of the structure of the male abdomen in this genus, new samples of I. pilosus Guinot & Richer de Forges, 1981 are recorded from the Philippines and a new species, Intesius richeri n. sp., is described, based on a specimen from New Caledonian waters. The latter can be distinguished from the two other species of the genus by its more rectangular carapace, a less developed pilosity (particularly on the walking legs), and the second male pleopods ending in a very slender tubular part. Two other specimens, from Guam, are described under the name I. lucius n. sp. They are very close to I. crosnieri Davie, 1998, known by a single specimen, but differ mainly by slightly longer, more slender and less pilose walking legs.
