Type material. Holotype: ♂ from Estação Ecológica de Una (14°48’S, 39°02’W), Una, Bahia, Brazil, X.1999 – IX.2000, leg. M.F. Dias, pitfall trap (IBSP 63986). Paratypes: Same data as holotype, 1♂ (IBSP 63985); Same locality as holotype, 15–28.XI.2000, leg. A.D. Brescovit et al., 1♀ (IBSP 46787).
Etymology. The specific name is a noun in apposition after the type locality.
Diagnosis. Males of Tupirinna una sp. nov. resemble those of T. caraca sp. nov. by the TEP parallel to the embolus and the RTA dorsal lobe long and with a blunt tip, but differ by the absence of an apical, prolateral tegular processs, and by the TEP and the embolus being similar in length (Fig. 16A, B). Females differ from those of all other species of Tupirinna by the presence of a conspicuous pair of anterior pockets (Fig. 16C, D).

Sternum yellow, with borders and anterior lateral excavations brown. Legs yellow, with lateral surfaces of patellae black; proximal and distal region of lateral surfaces of tibiae black. Abdomen dorsum grey, with pair of black longitudinal spots in cardiac area; in median region, two pairs of black spots on each side; subsequently one huge black subrectangular spot.
