Type material. Holotype: ♂ from Base de Operações Geólogo Pedo de Moura (04°52’07.6’’S, 65°15’53.6’’W), Porto Urucu , Coari, Amazonas, Brazil, 1.X.2004, leg. A.B. Bonaldo, D.F. Candiani & J.A. Marin-Fernandes, pitfall traps ( MPEG 35483 View Materials ). GoogleMaps  

Etymology. The specific name is a noun in apposition after the type locality.

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. 13E, F View FIGURE 13 ), and from those of T. zebra   by the lamellate dorsal process of the VL, which is sub-rectangular in ventral view.
