A new genus, Catanduba, is proposed and supported on the cladistic analysis with the following synapomorphies: embolus tapering abruptly from half of the length, embolus tooth associated with PIK and a triangular basal nodule on male metatarsus I. Homoeomma simoni and Plesiopelma flavohirtum are transferred to Catanduba and five new species are described: C. tuskae, C. araguaia, C. piauiensis, C. canabrava and C. peruacu. The species occur mainly in central Brazil, in Cerrado areas, with some species also occurring in Atlantic forest (C. tuskae sp. n. ) and Caatinga (C. piauiensis sp. n. and C. peruacu sp. n.).
