A new species of Mysidopsis (Crustacea, Mysida) from the Canary and Cape Verde archipelagos

<i>Mysidopsiscanariensis</i> sp. nov. is described from five islands of the Canaries and two islands of the Cape Verdes (NE-Atlantic). Records are from depths of 5 to 30 m, mainly over sand, also on stones and rock. It differs from the remaining NE-Atlantic and Mediterranean congeners amongst other features by the lateral margins of the telson distally having a longer bare portion. Amongst these species, it differs from its northern vicariants <i>M.iluroensis</i> and <i>M.gibbosa</i> in addition by fewer spines on the endopod of uropods. In-situ-photos of <i>M.canariensis</i> sp. nov. document at least six strongly different colour variants, four of which are strikingly similar to corresponding variants of <i>M.jenseni</i> from the NE-Pacific coast. The latter differs from all species of the E-Atlantic, including the new one, by a mid-dorsal lappet near the caudal margin of the female carapace. A key to the species of <i>Mysidopsis</i> from the E-Atlantic and Mediterranean is given.
