Abstract

Eumunida pictaSmith, 1883Smith, S.I. 1883. Preliminary report on the Brachyura and Anomura dredge in deep water off the South Coast of New England by the United States Fish Commission in 1880, 1881, and 1882. Proceedings of the United States National Museum, 6(1-4): 1-57, 6 pl., was considered for over a century an amphi-Atlantic species and the only representative of the genus in the Atlantic Ocean, until being split into three species: E. picta sensu stricto (from the northwestern Atlantic), E. bellade Saint Laurent & Macpherson, 1990de Saint Laurent, M. & Macpherson, E. 1990. Les espèces atlantiques du genre Eumunida Smith, 1883 (Crustacea: Decapoda: Chirostylidae). Journal of Natural History, 24: 647-666. and E. squamiferade Saint Laurent & Macphersonde Saint Laurent, M. & Macpherson, E. 1990. Les espèces atlantiques du genre Eumunida Smith, 1883 (Crustacea: Decapoda: Chirostylidae). Journal of Natural History, 24: 647-666., 1990 (from the northeastern and southeastern Atlantic, respectively). Eumunida is now expanded to include a new species, E. notialis, from off the Brazilian coast. Hence, this is the first record of Eumunida and Eumunididae from the southwestern Atlantic. The new species differs from all its Atlantic counterparts in having (1) four hepatic spines; (2) two carapace inframarginal spines; (3) the distal end of the antennal acicle nearly reaching to the articulation between fourth and fifth antennal segments; and (4) the anterolateral spine of the second pleonal tergite obsolete.
