A new species of Cyphocarididae (Crustacea, Amphipoda, Lysianassoidea) from off the northeastern Brazilian coast

Abstract

This paper describes a species of the genus Cyphocaris Boeck, 1871, the first record of the family Cyphocarididae Lowry & Stoddart, 1997 from Brazil. Two specimens, both females, were found in the stomach contents of a tuna caught in the Saint Peter and Saint Paul Archipelago. The new species is characterized by coxae 4 and 5 both large, coxa 4 partially overlapping coxae 2-3; coxa of pereopod 5 with ventral laminar projection and well-developed anteroventral lobe, broadly rounded and apically folded backwards, basis with anterior margin broadly rounded and posterior margin with large subacute naked projection (or spur); uropod 3, outer ramus paddle-shaped; and telson elongate and deeply cleft, with a nail.

A New Species of Cyphocaris Boeck, 1871 (Amphipoda: Lysianassoidea: Cyphocarididae): Found off the Rocas Atoll, Northeastern Brazil

“…Amphipods of the Cyphocarididae family have a cosmopolitan distribution and a very wide bathymetrical range from 90 to thousands of meters in depth [8,9]. Only one species, Cyphocaris pedroi Sorrentino, Alves, Johnsson & Senna, 2016, is reported for this family in Brazilian waters, which was sampled from the gut content of tuna from the Saint Peter and Saint Paul Archipelago off northeastern Brazil [10]. Here, we describe a new species of Cyphocaris from the southwestern tropical Atlantic, the second record of this genus for Brazil.…”
