The last list of species of the state of São Paulo State was updated and totaled 236 species of amphibians, 230 of which are anurans and six are caecilians. Bokermannohyla gouveai and Sphaenorhynchus surdus were removed from this list, because they did not occur in the State of São Paulo. The number of anuran species recorded comprise 27% of the species richness of the country and an increase by 31% in the number of species recorded for the state since 1998. Thus, despite the State of São Paulo be the Brazilian region where the anurans have been most studied, these data show that the number of known species tends to increase in the next years. We have identified two major geographical gaps of inventory: the southwest of the state, especially in the Paranapanema river basin and the northeast region, mainly at the border between the States of Minas Gerais and São Paulo. Although both have been sampled recently, information is still lacking. The current state of knowledge and perspectives in the areas such as taxonomy, systematics, ecology and conservation are evaluated.
