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, BView FIGURE 13, 19A, CView FIGURE 19). Females differ from those of all other Tupirinna  species by the wide, sub-trapezoidal copulatory opening ( Fig. 13C, DView FIGURE 13).
