Deep-sea Leuconidae (Cumacea, Peracarida) in the south-eastern Atlantic

The Leuconidae of the deep eastern Atlantic obtained during the German expedition Diva II and the French expeditions Zaiango and Biozaire 1 to 3 were analysed. Thirteen more or less frequently occuring leuconid species were found, including ten new deep-sea species from the Cape, Angola and Guinea Basin. The most speciose (ten species) genus is Leucon with three species in the subgenus Crymoleucon, four species in the subgenus Epileucon, one species in the subgenus Leucon and two species in the subgenus Makrauloleucon. A new genus-Afroleucon-is described, having penial lobes and only one pair of pleopods in males. One species each belongs to the genera Bytholeucon and Eudorella. Only three species, Leucon (Makrauloleucon) brigittehilbigae Mühlenhardt-Siegel 2005b, Leucon (Leucon) homorhynchus Bishop 1981a and Leucon (Epileucon) cf tenuirostris form A Bishop 1981b, were already known. The new species are: Afroleucon enigmatica n. g., Leucon (Crymoleucon) lufupa, L. (Crymoleucon) kafunta, L. (Crymoleucon) galeronae, L. (Epileucon) kapinga, Leucon (Epileucon) paraspiniventris, L. (Epileucon) paralongirostris, Leucon (Makrauloleucon) moritzi, Eudorella angolensis, and Bytholeucon kaingo. © 2010 Senckenberg, Gesellschaft für Naturforschung and Springer.
