New species and records of Flabellifera from the Indian Ocean (Crustacea: Peracarida: Isopoda)

In this study of flabelliferan Isopoda from the Indian Ocean, 19 species are described as new, in 11 genera and two families: family Cirolanidae, Baharilana koloura, B. lira, Cirolana aldabrensis, C. mimulus, C. somalia, C. undata, Eurydice paxilli, and Metacirolana chemola; family Sphaeromatidae, Cassidinidea clarkae, Cymodoce fuscina, C. lirella, Dynamenella alveolata, D. remex, Heterodina (new genus), H. mccaini, Oxinasphaera brucei, O. furcata, O. tetrodon, Paracilicaea stauros, and Sphaeromopsis sulcifera. Diagnoses of the genera and species are provided, and keys to the Indian Ocean species of most of the genera are provided. The material comes primarily from Aldabra Atoll, the granitic Seychelles islands, Zanzibar Island, and Phuket in Thailand. A few miscellaneous samples from the South African Museum collections, and from the International Indian Ocean Expedition carried out in the mid‐1960s are included.     

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 500m off Taiwan. The species' most distinctive feature, which readily distinguishes 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 500m. 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.
