Description of a new genus and species of the family Melphidippidae Stebbing, 1899 (Crustacea: Amphipoda) from the deep waters of Brazil.
The species of the amphipod family Melphidippidae are distributed worldwide in marine habitats, but there is no record of this family from Brazil so far. A new genus and species of Melphidippidae are described from Brazilian waters. Stebbingiella gen. nov. is monotypic and is distinguished from the other genera of the family by the presence of: antenna 1 with accessory flagellum 7-articulate, lateral cephalic lobe subacute, with globular eyes extremely produced, reaching beyond the second article of peduncle of antenna 2; gnathopods stout and slightly subchelate; coxae 3 and 4 with strong anterior projection and coxae 5 and 7 with strong posterior projection; telson cleft, not fully movable, with two globular lobes, about 2X wider than long. Stebbingiella globulosa sp. nov. is the first species of Melphidippidae recorded from Brazilian waters.
