SYNOPSIS

This paper reports on part of the species of Serolis Leach, 1818 (Crustacea, Flabellifera, Serolidae) collected from benthic stations performed during cruises of the Brazilian Navy Oc/S "Almirante Saldanha" along southern South America. The species studied are Serolis schythei Lütken, 1858, Serolis polaris Richardson, 1911, Serolis foresti Bastida & Torti, 1970, Serolis uaperta Moreira, 1971, Serolis exigua Nordenstam, 1933 and Serolis elliptica Sheppard, 1933. New localities of occurrence are reported, as well as it is given a com plete synonymy for each species treated, and for Serolis schythei and Serolis exigua also its main distinctive characteristics.
