Remarks. – This species is easily differentiated from other species of Hypocolpus by its densely setose carapace and the morphology of the subhepatic cavity, which is divided by two subparallel crests. All the adult specimens were collected in tangle nets. This species was first described from Aldabra Island in the Indian Ocean ( Rathbun, 1894 ), and has also been reported from nearby Madagascar (Guinot- Dumortier, 1960; Serène, 1984 ). In the western Pacific, it has been found in Amami-Oshima in southern Japan ( Takeda, 1972 ) and Taiwan ( Ho et al., 2000 ). This is the first record of Hypocolpus abbotti in the Philippines .
