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. albofasciata and 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 View FIGURE 16 ).

Endites yellow. Sternum and anterior lateral excavations yellow, with borders brown. Legs yellow, with lateral surfaces of patellae black; distal region of lateral surfaces of tibiae black. Abdomen dorsum yellow, with one pair of longitudinal black spots in cardiac area; in median region, two pairs of black spots on each side, followed by one subretangular black spot. Contour of spinnerets black; venter yellow ( Fig. 7F View FIGURE 7 ). Total length 5.82. Carapace length 2.59, width 2.09, height 1.15. Clypeus height 0.20.
