RESUMO
Bivalve mollusks (orders Arcoida and Ostreoida) collected during the BIOTA / FAPESP-Bentos Marinho Program and part of the REVIZEE / Bentos - Score Sul Program were analyzed in order to improve the knowledge about these taxa in Brazilian coast. The material was collected in soft bottoms in state of São Paulo from the intertidal zone to about 800 m depth, with cylindrical corers on beaches and van Veen, Box-corer dredge and trawl in the sublittoral zone. Bivalves were identified and photographed using a stereoscope microscope and a digital camera. A total of 1060 individuals were examined and 21 species recognized belonging to eight families: Arcidae (5 species), Limopsidae (3), Philobryidae (1) e Glycymerididae (2) (Arcoida); Ostreidae (1), Pectinidae (4), Propeamussiidae (4) e Anomiidae (1) (Ostreoida). There are two new occurrences for Brazilian coast, Bathyarca pectunculoides and Cyclopecten subimbrifer. Descriptions of some species were improved. A cluster analysis determined site groups related to depth
