| <i>Mangalocypria</i>, a new genus of the tribe Thalassocypridini, is described, with a new species, and two previously described species, from Papua New Guinea, the Comoros and Indonesia. The new genus has a remarkable set of characters separating it from other members in the tribe: thin-shelled, translucent and smooth valves, V-process of lower lip developed as a rake, and postero- distal claw of furca fixed to shaft without a joint. The affinities of <i>Mangalocypria</i> gen. nov. with other genera is discussed, and some taxonomical problems in the tribe Thalassocypridini are commented upon. The diagnostic value of incompletely differentiated Zenker organs of premature males is discussed. |
