Summary
Three new species of the Brazilian genus Luetzelburgia Harms (Leguminosae, Papilionoideae, Sophoreae sensu lato (Vataireoid clade)) are described and illustrated under the names Luetzelburgia harleyi D. Cardoso, L. P. Queiroz & H. C. Lima, L. neurocarpa D. Cardoso, L. P. Queiroz & H. C. Lima and L. purpurea D. Cardoso, L. P. Queiroz & H. C. Lima. All three occur in the caatinga vegetation of the State of Bahia, Eastern Brazil. A discussion of the morphological characters distinguishing the new species from their close relatives, as well as an identification key to all known species of Luetzelburgia, are presented.
Resumo
Três espécies novas do gênero Luetzelburgia Harms (Leguminosae, Papilionoideae, Sophoreae sensu lato (clado Vataireóide)) são descritas e ilustradas sob os nomes de Luetzelburgia harleyi D. Cardoso, L. P. Queiroz & H. C. Lima, L. neurocarpa D. Cardoso, L. P. Queiroz & H. C. Lima e L. purpurea D. Cardoso, L. P. Queiroz & H. C. Lima. Todas elas ocorrem na vegetação de caatinga do Estado da Bahia, Brasil. Uma discussão dos caracteres morfológicos que distinguem as novas espécies das mais relacionadas, bem como uma chave de identificação para todas as espécies de Luetzelburgia, são apresentadas.
