A New Species

Material collected on the central Brazilian coast from the REVIZEE Benthos Program was analyzed and three new species were herein described. Knowledge about sexual dimorphism on Bonassa is improved. The hypothesis of endemism of the genus Amaryllis to Australia is contested with the discovery of a new species of Amaryllis in the Southwestern Atlantic Ocean. A new species of Lysianassa is described, and its differences to L. brasiliensis are commented too. Lysianopsis concavus Senna, 2007 is herein described with more details in description and figures. The distributions of the described species are given. Keys to identification of Brazilian Lysianassoidea families and Lysianassidae species are presented in this paper.Key-words: Amaryllis, Bonassa, Lysianassa, Lysianopsis, taxonomy, Brazilian province

A New Species

A new species of Pseudione Kossmann, 1881, is described from 21 parasitized individuals of the squat lobster Munida microphthalma A. Milne-Edwards, 1880, collected in Brazilian waters of the southwestern Atlantic Ocean. The new species belongs to the Pseudione “crénéles” group sensu Bourdon (1976). The number of specimens obtained as well as the life history stage diversity of the type series, consisting of mature females, mature males, subadult males and cryptoniscus larvae, are unusually large for bopyrid isopod type series.

Sclerothyone Thandar, 1989, currently restricted to two South African species, is here expanded to include two new species from off coast of Brazil. These new species expand the distribution of the genus to the southwestern Atlantic Ocean. Sclerothyone reichi sp. nov. is characterized by having body wall with multilocular two pillared tables with multiperforate disc and short spire, ending in a narrow crown of teeth; tentacles with rods and introvert with two pillared tables and rosettes; tube feet with only end plates. Sclerothyone oloughlini sp. nov. is distinctive in having a body wall with multilocular, two pillared tables; handles present and multilocular two-pillared tables; circular disc without handle; and plates (near the anus). The new species resemble each other in the tentacles with rods. However, Sclerothyone oloughlini sp. nov. stands apart from S. reichi sp. nov. in the introvert with rosettes; tube feet with two pillared supporting tables, arched plates and end plates. The possible assignment of Cucumaria nozawai Mitsukuri, 1912 and Thyone adinopoda Pawson & Miller, 1981 to Sclerothyone, and the position of Thyone neofusus Deichmann, 1941 in Temparena Thandar, 1989, are briefly discussed. A key to all genera and species of Sclerodactylinae is provided.

Three New Species

Ampelisca species are inhabitant of soft bottom marine benthic communities of tropical to cold – temperate zones. Prior to this paper, 11 species of the genus were recognized from Brazilian coast. Three new species of Ampelisca are herein described: Ampelisca longipropoda, Ampelisca meridionalis and Ampelisca youngi. The specimens were dredged from the continental shelf of Southwestern Atlantic Ocean between the latitudes 22°06’S and 34°32’S. A key to the Ampelisca species of the Brazilian coast is provided.
