| Abstract |
Thirteen essentially (holo)pelagic species of Mysidacea (Lophogastrida and Mysida), plus fivebenthopelagic species were taken with vertical plankton hauls (mostly 1000-0 m depth) and byexamining the stomach contents of benthopelagic fish (from 550-700 m) in restricted areas ofthe NE Atlantic Ocean. The families Gnathophausiidae, Lophogastridae, and Eucopiidae are eachrepresented by two species, the Mysidae by 12 species. A first description of the previouslyunknown male and a supplementary description of the female are given for Longithorax alicei,so far known only from the Canary archipelago. First records for the northern hemisphere aregiven for two South Atlantic species, Boreomysis bispinosa from the Cape Verde archipelago andKaterythrops resimora from the Canary Islands. Additional new records for the Canary Islands areGnathophausia zoea, Lophogaster spinosus, and Longithorax nouveli. Among the 12 species ofMysidae examined, ten showed statoliths mineralized with fluorite (CaF), while two Boreomysisspecies showed comparatively soft, non-mineralized statoliths.Most of the 29 pelagic species so farknown from the Selvagens, the Canary, and the Cape Verde Islands belong to the circumtropicaldeep-water fauna. The local pelagic fauna shows no particular correspondence with that in theMediterranean, because the two areas have almost nothing but ubiquitous species in common. Bycontrast, ten benthopelagic species so far recorded from pelagic (plankton) samples off the CanaryIslands are endemic in the eastern Atlantic, in most cases including the Mediterranean. |
