Alagoas State is located in the northeast Brazil and was originally covered by Atlantic Forest and Caatinga. Nowadays, only small fragments of these two biomes remain mainly due to agricultural and pasture expansion. A few studies on amphibians in this area were conducted and a comprehensive species list is lacking precluding conservation strategies on amphibians in the state. To surmount this need, a list was compiled using both specimens housed in the herpetological collection of Museu de História Natural, Universidade Federal de Alagoas (MUFAL), and literature (species descriptions and distribution notes). Seventy-four species of amphibians allocated in 32 genera, 13 families and 2 orders were registered in Alagoas. The number of species from Atlantic Forest was about 2.6 times higher than the Caatinga. Hylidae was the richest family with 38 species (51% of total richness). Fifty-two species (70% of total) are considered as least concern according to IUCN, 11 (15%) are data deficient, one is vulnerable and five are still awaiting evaluation. Eight species have their type locality in the state, four are known only from Alagoas and two were registered in the state for the first time. Distribution patterns and taxonomic issues are discussed.
