Type material. Holotype: ♀from Campus19° Batalhão Caçadores( 14°48’S, 39°02’W), Cabula, Salvador, Bahia, Brazil, I–VI.2007, leg. D. Uzel et al., pitfall trap( IBSP 135845).

Etymology.The specific epithet is a noun in apposition referring to the goddess Obá, from the Afro-Brazilian religion candomblé.
Diagnosis.Females of Tupirinna oba sp. nov.share with those of T. caraca sp. nov.the recurved posterior transversal ridges on epigynal plate, and with those of T. albofasciataand T. palmares sp. nov.the presence of a well-defined median depression in the epigynal plate. They can be distinguished from the former by the larger, subrectangular copulatory opening, and from the latter by the presence of posterior transversal ridges ( Fig. 16E, F).
