Two species of deep-sea flabelliferan isopods from Taiwan (Crustacea : Peracarida : Aegidae, Anuropidae)

Aega falcata sp. nov. is described from two female specimens from about 500 m off Taiwan. The species' most distinctive feature, which readily disting uishes it from all others described, is the flattened falcate plates of the two basal articles of the antennular peduncle. Three specimens of Anuropus pacificus Lincoln and Jones, 1973, are recorded from 400 to 500 m. These i nclude a male, an ovigerous and a larvigerous female having numerous manca in the broodpouch. Given the rarity of specimens of Anuropus, all three for ms, as well as the manca, are described in some detail.
