Diagnosis

The habitus of this species, as well as the broadly rounded posterior margin of tergite VIII, resembles that of N. paralellus . However, N. sauron Guzman, Tokareva & Żyła sp. nov. differs from N. paralellus in the morphology of sternite VIII with a concave, broad emargination of the posterior margin and a glabrous midlongitudinal invagination on the rest of the sclerite ( Fig. 18E View Fig ), while it is deeply and narrowly emarginated in N. paralellus ( Herman 1991: fig. 88). Additionally, N. sauron differs in the shape of the apical complex of sclerites of the aedeagus ( Herman 1991: fig. 85; Fig. 18F–I View Fig ).

Etymology

The name is inspired by the structure of antiparameral sclerite in the aedeagus resembling the ‘Eye of Sauron’ in the movie trilogy ‘The Lord of the Rings’ based on J.R.R. Tolkien’s book series. A noun in apposition.

Distribution

This species is known from the type locality in Guyana (Upper Demerara-Berbice, Iwokrama Forest, Turtle Mountain) and the nearby Iwokrama Mountains. It was collected at a lower altitude with a flight interception trap.
