diagnosis
Diagnosis. Males of Tupirinna urucu sp. nov. differ from those of other species with the ventral lobe of the RTA divided basally (T. coari sp. nov. and T. zebra sp. nov.), as follows: from those of T. coari sp. nov. by the conical, elongated embolus, which is directed retro-apically (Fig. 13 E, F), and from those of T. zebra by the lamellate dorsal process of the VL, which is sub-rectangular in ventral view.
