Type locality. nr. Roura, French Guiana.

Description. Antenna mostly dark brown with narrow pale brown apices on scape, pedicel and most flagellomeres; tarsomere 3 of foreleg shorter than distal tarsomere; tarsomeres 1–4 of midleg not flattened ventrally; forewing with large dark brown spot at coalescing veins CuP+1A and posterior fork of CuA.

Holotype male. Length of body 20.5 mm., forewing length 21 mm., width 5.0 mm., hindwing length 20.5 mm., width 3.5 mm; wing span 42 mm. Coloration: Face ( Fig. 4 ) pale brown ventrally with broad dark brown band below antennae, not reaching ocular rim but extending dorsally to fuse with large dark brown area above antenna; maxillary and labial palpi pale brown basally, dark brown on apical palpomeres; antenna ( Fig. 36 ) mostly dark brown with narrow pale brown apices on scape, pedicel and most flagellomeres, mostly pale brown toward apex which is mostly dark brown vertex ( Fig. 13 ) mostly dark brown to black, with narrow transverse pale brown stripe submedially near middle; pronotum ( Fig. 13 ) nearly all dark brown medially and laterally; pteronotum dark brown laterally, pale brown sublaterally on prescutum, mesonotum, mesoscutellum; metanotum dark brown except anteriorly and medially; metascutellum dark brown; thoracic pleura ( Fig. 22 ) mostly dark brown with scattered pale brown areas; coxae mostly pale brown with small darker brown areas; legs light brown with darker areas at base of set; forewing ( Fig. 41 ) with small dark brown rhegmal mark and large dark brown spot at coalescing veins CuP+1A and posterior fork of CuA; abdominal tergites mostly dark brown except tergites 1–2, other tergites mostly pale brown area anteriorly. Chaetotaxy: Face and vertex with brown setae, labrum with pale setae; scattered dark brown setae on antennal scape, pedicel, and flagellomeres; pronotum with many long setae, as long as, or longer than, the longest setae on the clypeus; pterothoracic nota nearly without setae except laterally on prescutum; pterothoracic pleura without setae except ventrally; forefemoral sense about equal to femur diameter, midfemoral sense hair not distinguishable from surrounding white setae; femora and tibiae with short setae, mostly shorter than femur diameter, a few somewhat longer; ventral setae on distal tarsomere of foreleg longer than middle diameter of tarsomere, not hooked; ventral setae on other legs about equal in length to middle diameter of tarsomere. Structure: Distal palpomere of labius moderately swollen; antenna ( Fig. 36 ) with most flagellomeres about 2 times longer than wide, weakly clavate; pronotum longer than wide; foreleg tarsomere 3 shorter than distal tarsomere; midleg tarsomeres 1–4 longer than distal tarsomere; forewing with costal cells broader than long basally, higher than wide near and beyond origin of radial sector, with 7 presectoral crossveins; forewing radial sector arises well beyond cubital fork; posterior fork of CuP+1A reaches hind margin well distal of radial sector ( Fig. 41 ). Male genitalia ( Fig. 49 ): With gonarcus nearly uniformly broadened, strongly arched, narrowed distally, no mediuncus; paramere strongly appressed to gonarcus, elongate, about 4 times longer than middle diameter, sculptured mainly in rows, strongly sclerotized on mesal margin bending strongly near middle exposing ventral paramere structure; large, ovoid sclerite separating parameres near gonarcus, with strong sculpture.

Distribution. French Guiana.

Collection times. April and November.

Material studied. Holotype male and 1 paratype male.

FRENCH GUIANA. 33 km. southeast Roura on Kaw Rd., 12–13.IV.2007, D. Hall and J. Eger (1m, FSCA); Route de Kaw PK4, 25.XI.1997, Piége lumineux (1m, FSCA).

Discussion. This species (along with N. brasiliensis ) can be recognized by the combination of having the pronotum with many long setae, as long as, or longer than the longest setae on the clypeus, forewing with small dark brown marks; posterior fork of CuP+1A of forewing reaching hind margin of wing beyond radial sector, and having unhooked setae on the distal tarsomeres of the forelegs.

Etymology. This species is named for Joseph Eger, who collected the holotype.
