Etymology. The specific name is a noun in apposition, in reference to the white and dark pattern of the abdomen, ressembling that of a zebra. Diagnosis. Males of Tupirinna zebra sp. nov. differ from those of other species with the ventral lobe of the RTA divided basally ( T. coari sp. nov. and T. urucu sp. nov. ), as follows: from those of T. coari sp. nov. by the conical, elongated embolus, which is directed retro-apically, and from those of T. urucu sp. nov. by the lamellate dorsal process of the VL (dVL) tapering apically in ventral view ( Figs 13A, B , 19A, C ). Females differ from those of all other Tupirinna species by the wide, sub-trapezoidal copulatory opening ( Fig. 13C, D ). Description. Male holotype (SMNK). Carapace orange, with brown median stripe extending over ocular area, and brown lateral stripes. Chelicerae dark brown. Labium brown. Endites brown. Sternum yellow, anterior lateral excavations brown. Legs yellow.

Contour of spinnerets-brownish grey; venter pale yellow ( Fig. 5A ). Total length 4.99. Carapace length 2.44, width 1.99, height 1.11. Clypeus height 0.23.
