The agile snouted tree frog Scinax agilis (Anura, Hylidae) is one of the restinga frog species, with reported distribution in the Espírito Santo, Alagoas, Sergipe and Bahia states, especially in sand dune habitats, known locally as restinga. On the north coast of Bahia, north-eastern Brazil, it is known, according to literature, only from the cities Camaçari and Mata de Sao Joao. In this study we fill the geographic distribution gap in the region including presence in six new localities and cities. We also report findings on diurnal and nocturnal activity patterns and the use of microhabitats at the different vegetation type habitats. We found S. agilis in dry forest, scrub and beach vegetation and also at the temporary or permanently flooded river plains. Most records (52.2%) were on river plains during daytime surveys mainly from 1200 to 1800 hours. Bromeliads were the most frequently used microhabitat (45.4%) followed by aquatic plants. The agile snouted tree frog association with flooded river plains and associated plant communities reinforces the urgent need for conservation measures to preserve the restinga remnants in the region.
