Crustacea Amphipoda Pareurystheus vitucoi sp. nov. Photis guerrai sp. nov. NW Atlantic upper slope hard bottoms


Two new species of the Suborder Senticaudata (Corophiidae and Photidae) are described. They were collected during the expeditions “DIVA ARTABRIA I” in 2003 and “A Selva” in 2008, off the Galician coast (NW Iberian Peninsula). Samples were taken on hard bottoms between 800 and 1000 m deep using different gears (an epibenthic sledge an Agassiz trawl and a naturalist dredge). The corophiid Pareurystheus vitucoi sp. nov. is a blind species that can be easily distinguished from the other known genus species by the size and shape of pereopod 5. The photid Photis guerrai sp. nov is also a blind species, characterized by the presence of an anterodistal lobe on the basis of gnathopod 2. A key to the genera of Protomedeiinae is also included, as well as keys for the species of the genus Pareurystheus and the Atlantic and Mediterranean species of the genus Photis.
