Ocorrência e distribuição da subordem Hyperiidea (Crustacea : Amphipoda) para o Oceano Atlântico Sul Ocidental (02. - 40.S)
Study of the occurrence and distribution of the species of suborder Hyperiidea found in the area between 02º and 40°S, thus filling a gap in the Western South Atlantic Ocean, with bore scant work on the group. The four collections selected, comprising the Northeastern, Center, Southeastern and South...
