Description
Summary:A survey of the tribe Justicieae from the Caatinga biome, in the State of Bahia, revealed the following four new species of Justicia (Acanthaceae): J. angustissima, J. attenuata, J. chlamidocalyx and J. jacuipensis. J. attenuata and J. jacuipensis are known only from the types; the latter is considered Critically Endangered (CR) because the area where it was collected has been flooded since the construction of the Pedra do Cavalo dam and the region around this area has been extensively disturbed. J. angustissima and J. chlamidocalyx were found in six locations. They have a wide distribution in Central Bahia and the conservation status of both species should be classified as Least Concern (LC). The four species are described and illustrations and comments are provided. O levantamento de Justicieae do Bioma Caatinga no Estado da Bahia propiciou o reconhecimento de quatro espécies novas de Justicia (Acanthaceae): J. angustissima, J. attenuata, J. chlamidocalyx e J. jacuipensis. J. attenuata e J. jacuipensis são conhecidas apenas pelo material-tipo; a última pode ser considerada Criticamente Ameaçada (CR), pois a área onde foi coletada encontra-se inundada pela represa Pedra do Cavalo e seu entorno encontra-se extensamente antropizado. J. angustissima e J. chlamidocalyx foram encontradas em seis localidades, mas apresentam uma distribuição relativamente ampla no interior da Bahia e o estado de conservação delas inspira menor preocupação (LC). As quatro espécies são descritas, ilustradas e comentários são apresentados para cada uma delas.
