Redescription and first record of Camacho faroensis Myers, 1998 (Crustacea, Amphipoda) from the continental slope off Galicia (NW Iberian Peninsula)

This paper reports the southernmost record of Camacho faroensis Myers, 1998 (Crustacea: Amphipoda: Aoridae) from samples collected at the continental slope (Ferrol Canyon) off the NW Iberian Peninsula during the DIVA-Artabria I expeditions. This species was initially described from the Faroe Islands but type specimens are incomplete and lack relevant features (e.g., antenna 1, pereopod 5). Therefore, a detailed redescription and drawings are provided based on examination of the type series and the new material collected. To date, the genus Camacho Stebbing, 1888 is composed of three species being C. faroensis as the only one reported so far from the Northern Hemisphere. This species is characterized by the following characters: absence of eyes, cephalic lobes reduced, presence of two ventral spines on peduncle article 1 distal margin of antenna 1, presence of spines (stout setae) on pereopods 5–7, reduced inner rami of uropod 3, and lacking distal setae. A key for all recognized species of the genus is also included.
