This expedition reveals 8 new leuconid species in the Argentine and Brazil basins, suggesting rich biodiversity.
The Leuconidae (Cumacea) from the expedition DIVA 3 with RV Meteor to the Argentine and Brazil Basins (July to August 2009) were analysed, 8 new species and 1 new genus are described. These species are Bytholeucon paucidentatis sp. nov., Eudorella paramonodon sp. nov., Eudorellopsis dentata sp. nov., Leucon (Alytoleucon) argentinensis n.sp., Leucon (Crymoleucon) pinocchio sp. nov., Leucon (Leucon) brevirostratis sp. nov., Leucon (L.) paravasilei sp. nov., and Remyleucon hyalorostris gen. nov. sp. nov.
