We report here the first occurrence of Bangiopsis subsimplex (Mont.) F.Schmitz (Rhodophyta) for the northeastern coast of Brazil. The specimen was isolated from a laboratory sample of mollusk shells collected in Baía de Todos os Santos (Bimbarras Island, Brazil) and was held in sterilized seawater (33 UPS) enriched with 25% Provasoli solution. In the American Atlantic region, B. subsimplex presents a northern distribution limit at French Guiana and a southern limit at São Paulo. We conclude that the distribution of B. subsimplex has expanded, since the species was once known only to the southeastern Brazil, specifically to São Paulo.
