The records extend the distribution of Hypsiboas boans Leptodactylus syphax Bokermann, 1969 for the state of Maranhão.

These records extend the current geographic distribution of Hypsiboas boans (Linnaeus, 1758) eastward. The distribution of this species was limited to the Amazon basin and has now expanded to the Cerrado biome in the northeastern region of the state of Maranhão. Also this Leptodactylus syphax Bokermann, is the first record of 1969 for the state of Maranhão. The identifications were confirmed by the experts Dr. Ulisses Caramaschi and Dr. Marcelo Felgueiras Napoli, after comparisons with specimens deposited at the Museu Nacional, municipality of Rio de Janeiro, Brazil (MNRJ),The Instituto and Museu Chico de MendesZoologia deda ConservaçãoUniversidade da Federal Biodiversidade da Bahia, – municipality ICMBio (License of Salvador, number 20896-1)Bahia, Brazil provided (UFBA). permit to collect specimens.
