Diagnosis

Similar to N. apiculus and N. campbelli in the shape of the posterior margin of sternite VIII and tergite VIII. However, N. napo Guzman, Tokareva & Żyła sp. nov. differs from these species by the different structure of apical sclerites of aedeagus, especially, by much larger bifid protruding APS ( Herman 1991: figs 170, 174; Fig. 10F–G ).

Etymology

The epithet ‘napo’ is derived from the toponym of the type locality near the Napo River basin in Ecuador. A noun in apposition.

Metasternal intercoxal process with 1 pair of acute processes. Elytron longer than wide, surface of elytra with moderately dense umbilicate punctures in 8–9 longitudinal rows ( Fig. 10A ; Supp. file 2).

LEGS. Protibia with 4 well-developed combs of setae; apical comb longitudinal, composed of widely separated, thick setae; mesotibial apical ctenidium on both sides, inner longer than outer; mesotarsomere 1 longer than 2, metatarsomeres 3 and 4 as long as 2, mesotarsomere 5 longer than 1; inner ctenidium of metatibia longer than outer; metatarsomere 1 longer than 2, metatarsomeres 2, 3 and 4 equal, metatarsomere 5 as long as metatarsomere 1.

ABDOMEN. Male: tergites with low-density randomly distributed micropunctuation. Posterior margin of tergite VII straight ( Fig. 10B ). Posterior margin of sternite VII sinuate ( Fig. 10C ). Posterior margin of tergite VIII apically rounded ( Fig. 10D ). Posterior margin of sternite VIII with midlongitudinal glabrous depression and midpoint U-shaped emargination, 1/5 of segment length, lateral angles rounded ( Fig. 10E ). Posterior margin of tergite IX with midlongitudinal deep emargination in ¾ of segment length; aedeagus, in parameral view, median lobe widest at middle, with pair of oval invaginations on sides from basal foramen to apex of lobe, apex of median lobe with 2 flattened processes. pPMS of complex form, with 2 pairs of acute triangular arms protruding towards parameral side. pLS longer than pPMS and APS, fused into plate on parameral side, with 2 acute flat triangular elongate arms bent towards parameral side. APS flat, with 2 long arms with rounded tips aligned with pLS ( Fig. 10F–I ). Female: unknown.

Distribution

This species is known from the type locality in Ecuador (Sucumbíos, Shushufindi), and Suriname (Sipaliwini, Kabalebo). It was collected at low altitudes between 25 to 270 m a.s.l. using Malaise and flight interception traps.
