Abstract This study presents a floristic survey of Malpighiaceae species from in the Raso da Catarina Ecoregion in the state of Bahia, Brazil. After extensive field and herbarium studies, we identified 18 genera and 32 species of Malpighiaceae in the study area: Aspicarpa harleyi W.R.Anderson, Banisteriopsis C.B.Rob. (3 spp.), Barnebya harleyi W.R.Anderson & B.Gates, Bronwenia ferruginea (Cav.) W.R.Anderson & C.C.Davis, Bunchosia pernambucana W.R.Anderson, Byrsonima Rich. ex Kunth (4 spp.), Carolus chasei (W.R.Anderson) W.R.Anderson, Diplopterys lutea (Griseb.) W.R.Anderson & C.C.Davis, Galphimia brasiliensis (L.) A.Juss., Heteropterys Kunth (5 spp.), Janusia anisandra (A.Juss.) Griseb., Mascagnia Bertero (2 spp.), Mcvaughia bahiana W.R.Anderson, Peixotoa hispidula A.Juss., Ptilochaeta Turcz. (2 spp.), Stigmaphyllon A.Juss. (3 spp.), Tetrapterys Cav. (2 spp.) and Thryallis longifolia Mart. Among the species recorded, three represent new records for the Caatinga biome, 25 are endemic to Brazil, and six are exclusive to the Caatinga. We present an identification key to all species, comments on morphology, taxonomy, distribution and phenology, besides illustrations to most species.
