Abstract
A new and endangered species, endemic to dry forests of the Caatinga Domain in Northeast Brazil is described and illustrated. Ipomoea vespertilia has been misidentified in herbaria as I. marcellia, to which it appears to be closely related. However, it differs consistently from that species in multiple morphological characters and the timing of anthesis.

Keywords: Anthesis, biodiversity, Brazilian flora, cytotaxonomy, integrative taxonomy

Resumo: É descrita uma nova espécie ameaçada de extinção e endêmica do domínio da Caatinga, Nordeste do Brasil. Ipomoea vespertilia estava incorretamente identificada nos herbários como I. marcellia, com a qual parece ser proximamente relacionada. No entanto, além de diferenças morfológicas consistentes, é reconhecida por um período de antese distinto.
