Type locality. Virmond, Paraná, Brazil.
Description. Forewing (Fig. 40) with large dark brown spot at coalescing of vein CuP+1A and posterior fork of CuA near posterior border; pronotum (Fig. 12) with many long setae, as long as, or longer than the longest setae on the clypeus; foreleg tarsomere 3 shorter than distal tarsomere.
Holotype male. Length of body 15 mm., forewing length 21 mm., width 5 mm., hindwing length 21.5 mm., width 4 mm; wing span 44 mm. Coloration: Face (Fig. 3) pale brown with broad dark brown band below antennae and small dark brown area above antenna at middle; antennal scape and pedicel mostly dark brown; vertex (Fig. 12) with reduced dark brown markings, anterior vertex row most prominent; pronotum (Fig. 12) with broad pale yellow band at middle, broad dark brown band laterally; pterothoracic nota mostly dark brown with pale yellow scutelli; pterothoracic pleura mostly dark brown (Fig. 21); abdomen mostly dark brown but broad pale brown band on sternites; forefemora and midfemora and tibia brown with numerous small dark brown spots, rest of legs mostly pale brown; forewing (Fig. 40) with large dark brown spot at coalescing of vein CuP+1A and posterior fork of CuA near posterior border. Chaetotaxy: Maxillary and labial palpi with abundant black setae about as long as flagellomere diameter; thoracic nota (Fig. 21) without setae except pronotum mostly laterally and prescutum; pronotum (Fig. 11) with many long setae, as long as, or longer than the longest setae on the clypeus; pterothoracic pleura (Fig. 21) without setae except few small ones ventrally; forefemoral and midfemoral sense hairs short, about equal to femur diameter; femora and tibiae with short setae, shorter than femur diameter. Structure: Distal palpomere of labius slender (Fig. 3); flagellum missing; pronotum longer than wide; foreleg (Fig. 21) about same length as hindleg; foreleg tarsomere 3 shorter than distal tarsomere; midleg tarsomeres 1–4 longer than distal tarsomere; forewing (Fig. 40) about same length as hindwing, forewing radial sector arises well distad of cubital fork, with 8 presectoral crossveins; forewing costal cells above radial sector higher than wide. Male genitalia (Fig. 48): With gonarcus strongly arched, nearly uniform in width, with barely indicated mediuncus; parameres elongate, shallowly sculptured, about 5 times longer than wide, diverging posteriorly, nearly touching at anterior one-third.
Female. About as described for male. Female terminalia (Fig. 55, 56): With small pregenital plate but medial tooth long; posterior gonapophysis strongly swollen, about as long as wide, with some setae
that are about as long as gonapophyseal width; lateral gonapophyses fused, large and transverse, with many narrow digging setae on most of surface; ectoproct with few small scattered setae; spermatheca at least 12 times longer than wide, broadly curved.
Distribution. Brazil.
Collection times. January and March.
Material studied. Holotype male, 1 male paratype, 1 female paratype.
BRAZIL. Paraná: Virmond (1m, FSCA). Rio de Janeiro: Guanabara, Floresta da Tijuca, 13.I.1969, L. Stange (1m, FSCA) São Paulo, Ilha da Vitoriá, 16-27.III.1964 (1f, FSCA).
Discussion. This is the second species known in the genus with markings on the forewing. The other species is N. egeri. The female posterior gonapophysis are the most swollen in the genus. The two paratypes are in bad condition.
Etymology. This species is named after the country where the holotype was collected.
