Etymology. The specific name is a Latin adjective meaning wide, in reference to the wide, inverted T-shaped copulatory pouch.
Diagnosis. Males of Tupirinna lata sp. nov. resemble those of T. palmares sp. nov. by the TEP dorsal in relation to the embolus, but differ by the presence of a relatively large, medially inserted RTA dorsal lobe and by the narrow-based, spiniform embolus (Fig. 14E, F). Females are readily distinguished from those of all other Tupirinna species by the wide, inverted T-shaped copulatory pouch (Fig. 14G, H).
