Acacia Mill. in the traditional sense embraces c. 1,400 species from tropical areas of the World. Phylogenetic studies carried out since the decade of 1990 have shown that the genus is polyphyletic and should be split into five genera. Species native to the Caatinga of Northeastern Brazil belong to the former subgenus Aculeiferum, a group now segregated from Acacia and renamed as Senegalia. In this work, eight new combinations are presented in this genus: Senegalia bahiensis (Benth.) A.Bocage & L.P.Queiroz, Senegalia kallunkiae (J.W.Grimes & Barneby) A.Bocage & L.P.Queiroz, Senegalia langsdorffii (Benth.) A.Bocage & L.P.Queiroz, Senegalia martiusiana (Steud.) A.Bocage & L.P.Queiroz, Senegalia monacantha (Willd.) A.Bocage & L.P.Queiroz, Senegalia piauhiensis (Benth.) A.Bocage & L.P.Queiroz, Senegalia santosii (G.P.Lewis) A.Bocage & L.P.Queiroz and Senegalia velutina (DC.) A.Bocage & L.P.Queiroz.
