Abstract: Scartella itajobi in the São Pedro e São Paulo Archipelago,

This article presents the first record of the blenniid located off the state of Rio Grande do Norte, northeastern Brazil. As a result, the species distribution is extended 610 km northeast. The number of species of Blenniidae known to occur in São Pedro e São Paulo Archipelago is three, whereas the number of endemic fish species shared by São Pedro e São Paulo, Fernando de Noronha, and Rocas Atoll now stands at two.

São Pedro e São Paulo Archipelago (SPSPA) is a group of The record of S. itajobi in SPSPA represents a small islands and rocks located approximately 1000 km off the coast of Rio Grande do Norte State, northeastern Brazil from the supposedly northern limit of distribution of the (Figure 1). It shares about 80% of its fauna, including distributional extension of approximately 610 km northeast
