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 ).
