Type locality. Amazonas, Brazil.

Description. Pronotum longer than wide; foreleg distal tarsomere shorter than basal four tarsomeres together; antenna nearly all black; forefemur nearly all black with femoral sense hair about three times longer than femur diameter, equal to midfemoral sense hair; forewing unmarked; forewing radial sector arises well before cubital fork; female posterior gonapophysis greatly swollen, about twice as long as wide.

Holotype male. Length of body 15 mm., forewing length 23.5 mm., width 6 mm., hindwing length 23 mm., width 5 mm. Coloration: Face brownish with darker brown area at middle below antennae; antenna ( Fig. 19 ) nearly all black except pale scape and pedicel; maxillary palpus dark brown, labial palpus pale brown; vertex ( Fig. 10 ) mostly pale brown with dark brown area submedially at middle and anteriorly; pronotum ( Fig. 10 ) mostly pale yellow anteriorly extending posteriorly as narrow pale band medially, pale brown laterally with large dark brown submedian area on posterior one-half;;pteronotum nearly all dark brown; pterothoracic pleura ( Fig. 19 ) mostly pale yellow with dark brown anteriorly; abdomen mostly dark brown with most pale brown areas on tergites 1–3; forefemur nearly all black; forewing ( Fig. 38 ) unmarked; hindwing without hypostigmal dark brown spot. Chaetotaxy: Antenna densely covered with short pale setae; thoracic nota ( Fig. 10 ) without setae except pronotum mostly laterally and prescutum; pterothoracic pleura ( Fig. 19 ) without setae except few small dark ones ventrally; forefemoral sense hair about three times longer than femur diameter, equal to that of midfemur; distal tarsomere with many short, stout black setae along nearly entire distal surface; femora and tibia ( Fig. 19 ) with dark setae shorter than femur diameter. Structure: Distal flagellomere slender; antenna weakly clavate, most flagellomeres before clava longer than wide; pronotum longer than wide; foreleg basitarsus shorter than distal tarsomere and pretarsal claws; forewing radial sector ( Fig. 38 ) arises at or somewhat beyond cubital fork, 6 presectoral crossveins. Male genitalia ( Fig. 47 ): With atypical gonarcus apparently partly separated in two broad halves, not arched, without mediuncus; parameres weakly sculptured, elongate, about 7 times longer than wide, broadly separated at gonarcus, converging posteriorly, produced anteriorly beyond gonarcus, separated by prominent ovoid sclerite posteriorly.

Female. About as described for male. Female terminalia ( Fig. 53 ): With posterior gonapophysis swollen, especially basally, about twice as long as wide, with all setae shorter than gonapophyseal width; lateral gonapophysis elongate with scraping setae concentrated in transverse rows posteriorly; pregenital plate appears large (not clear from photo); ectoproct with only fine setae ventrally, spermathecal not visible in photo.

Distribution. Brazil.

Collection times. January and July.

Material studied. Holotype male, 1 male paratype, 2 female paratypes.

Discussion. The male genitalia ( Fig. 47 ) of N. amazonas is distinctive and highly modified in comparison to other species of the genus. Also, the wings are unmarked in contrast to other species of the group. The femoral sense hair is intact only in the holotype. They appear broken in other specimens.

Etymology. The name is based on the Brazilian state from which the holotype was collected.
