Crabs of the family Xanthidae (Crustacea: Brachyura) from the Philippine Islands and adjacent waters based largely on collections of the U.S. Fish Commission steamerAlbatrossin 1908–1909

Abstract

Summary Most of the specimens were collected by the U.S. Fisheries Steamer ‘Albatross’ from 84 stations of Philippines and adjacent waters during 1908–1909. Sixty-six of these (78·6%) range in the area of 4°N–14°N in Latitude and 119°E–126°E in Longitude, and 52 of these (62%) are included in the southern part of the area (south of Negros—N. Mindanao, 9°N); the bathymetric range is from the intertidal zone to a depth of 618 m; several specimens were collected by non-Albatross collectors from the Philippine Islands. The total number of 60 identified species are distributed among six subfamilies and 30 genera. Of the six subfamilies, the Pilumninae were overwhelmingly represented with 29 species belonging to eight genera. The genus Pilumnus alone was represented by 12 species, Actumnus by five species, Glabropilumnus by four species. It was in the Pilumninae also that the new species were concentrated: of Parapilumnus, three, and of Actumnus, Neoactumnus, and Glabropilumnus, one each, for a total of six new...
