Etymology. The specific name is a Latin adjective meaning gigantic, an allusion to the larger size of this species compared to the remaning Tupirinna .

Diagnosis. Males of Tupirinna gigantea sp. nov. differ from those of all other species with basally divided ventral lobe of RTA ( T. coari sp. nov., T. zebra sp. nov. and T. urucu sp. nov.) by the bifid ventral process of the ventral lobe of the RTA ( Fig. 11E View FIGURE 11 ). They further resemble those of T. coari sp. nov. by the short embolus, directed retrolaterally, and the long, narrow AS, differing by the filiform, curved embolar tip ( Fig. 11E, F View FIGURE 11 ). Females resemble those of T. coari sp. nov. by the concave epigynal plate, but can be recognized by the posteriorly positioned copulatory opening ( Fig. 11G, H View FIGURE 11 ).

Description. Male holotype (ICN – Ar 10640). Carapace brown, with black stripe extending over ocular area, and black lateral stripes. Chelicerae brown. Labium brown. Endites brown.
