The ophiuroids were collected during the Programs "Biodiversidade Bêntica Marinha no Estado de São Paulo" - BIOTA/FAPESP-Marine Benthos, "Avaliação do Potencial Sustentável dos Recursos Vivos da Zona Econômica Exclusiva" - REVIZEE/Score South - Benthos and "Utilização Racional dos Ecossistemas Costeiros da Região Tropical Brasileira: Estado de São Paulo" - INTEGRADO/Subproject Benthos. Samples were obtained from the continental shelf and slope off southeast and south Brazil, between 10 and 800 m. Four species of the Ophiuroidea are described and they are new records for Brazil. Two species belong to the family Ophiuridae, and the others belong to Amphiuridae and Ophiochitonidae. The family Ophiochitonidae is recorded for the first time in Brazil. Amphiodia trychna (Amphiuridae) was sampled in the inner continental shelf (depth < 50 m). The other three species were collected deeper (between 314 and 808 m).
