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

Journal of Natural History 35 (4): 481-496, DOI: 10.1080/00222930151098152 Aega falcata sp. nov. is described from two female specimens from about 500 m off Taiwan. The species’ most distinctive feature, which readily distinguishes it from all others described, is the fl attened 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 include a male, an ovigerous and a larvigerous female having numerous manca in the broodpouch. Given the rarity of specimens of Anuropus, all three forms, as well as the manca, are described in some detail.
