Etymology. The specific name is a noun in apposition after the type locality.
Diagnosis. Males of Tupirinna cruzes sp. nov. resemble those of T. caraca sp. nov. and T. una sp. nov. by the TEP parallel in relation to the embolus, but differ by the small dorsal lobe of the RTA, which has an acute tip, and by the long, filiform TEP (Fig. 15A, B). Females share with those of T. caraca sp. nov. and T. oba sp. nov. the epigynal plate with transverse posterior ridges, but can be readily recognized by the procurved posterior transverse ridges (Fig. 15C, D).
Description. Male holotype (IBSP 54625). Carapace brownish-orange, with dark brown median stripe gradually lighter and narrowly extending over ocular area, and black lateral stripes. Chelicerae brown. Labium brown. Endites yellow. Sternum yellow, with borders brown and anterior lateral excavations dark brown. Legs yellow, with lateral surfaces of patellae (proximal region), tibiae (proximal and distal regions) and distal region of metatarsi black. Abdomen dorsum yellow, with two pairs of longitudinal black spots in cardiac area; in median region, two pairs of black spots on each side; subsequently two black spots in middle, followed by a semicircular black spot.
