| Abstract |
The Nannastacidae of the deep south-eastern Atlantic obtained during the German expedition DIVA II and the French expeditions ZAIANGO and BIOZAIRE 1 to 3 were analysed. Thirteen more frequently occurring nannastacid species were found, including seven new deep-sea species and a new genus from the Cape, Angola and Guinea Basins: Campylaspides armatus sp. n., Bathypicrocuma ifrmer gen. and sp.n., Styloptocuma dentatum sp. n. , S. cuspidatum sp. n., S. paucidentatum sp. n., Styloptocuma enigma sp. n., and Thalycrocuma barbatulum sp. n. The species Procampylaspis lucida and Campylaspis serratocarinata had already been described for the Angola Basin but remained in open nomenclature. After their rediscovery, they were now named. The species Styloptocuma minimum, S. pleonserratum and Platycuma lineata were already known from the Angola Basin and were now rediscovered in the Cape and Guinea Basins. The species Atlantocuma tenuis was already known as widespread in the Atlantic. The most speciose genus in the family Nannastacidae described here is Styloptocuma with six species, four of which are new. |
