Description. Male. Length = 5.0 mm (n = 3).
Head. Fronto-orbital, parafacial plates and postocular strip with golden microtomentum. Frontal vitta black. Six frontal setae. Gena and postgena with golden microtomentum. Palpus yellow.
Thorax. Chaetotaxy: dorsocentrals 2+4 (first two weak); intra-alars 2+3; supra-alars 2+3, notopleurals 1 subprimary; anepisternals 5; merals 5. Ctenidium consisting of four spines. Mid femur with two median setae and with a differentiated posteroventral seta. Wing hyaline; vein R 4+5 setulose dorsally to crossvein r-m.
Abdomen. Tergites brown with a band of grayish microtomentum on anterior 4/5 of dorsal and lateral surfaces. Sternites 2 and 3 orange with a median brown strip on posterior margin; sternite 4 brown, with yellowish setulae and marginal setae.
Terminalia. Sternite 5 brown, with long and short slender setae; cleft shallow, not passing the anterior margin of lobe; lobe rounded and with a tuft of short setulae; arms divergent and glossiform ( Fig. 19E View FIGURE 19 ). Cercus sinuous, short- er than epandrium, without setulae on cercal prong, with a small preapical protuberance on dorsal surface and with tip strongly curved posteriorly in lateral view ( Fig. 19A View FIGURE 19 ). Cercal prongs with convergent rectangular apex in dorsal view ( Fig. 19B View FIGURE 19 ). Surstylus elongate, tapering distally, with pointed apex curved posteriorly, with setulae restricted to basal margin ( Fig. 19A View FIGURE 19 ). Pregonite claw-shaped, curved anteriorly, bearing small, pointed setulae on posterior margin ( Fig. 19C View FIGURE 19 ). Postgonite shorter than pregonite, with pointed apex curved anteriorly, anterior margin bearing a long seta and small pointed setae ( Fig. 19D View FIGURE 19 ). Basiphallus elongate, about half as long as distiphallus ( Fig. 19F View FIGURE 19 ). Distiphallus L-shaped, with rounded apical margin ( Fig. 19F View FIGURE 19 ). Ventral margin of distiphallus with a small, pointed projection and with serrated margin ( Fig. 19F View FIGURE 19 ). Vesica strongly angled, with a basal triangular projection and with pointed apex strongly curved in lateral view ( Fig. 19F View FIGURE 19 ). Inner process of vesica elongate and curved posteriorly ( Fig. 19F View FIGURE 19 ). Lateral and median styli short, of about one-fourth width as the widest portion of lateral wall of distiphallus, and both inserted medially in distiphallus ( Fig. 19F View FIGURE 19 ).
Female. Unknown.
Etymology. The specific name, which should be treated as a noun in apposition, is derived from the name “Matinta Pereira”, who in the Brazilian folklore is a witch dwelling in the Amazon forest.
Distribution. NEOTROPICAL—Brazil (Amazonas, Pará, Roraima).
Remarks. This species differs from the others in having surstylus with distal portion pointed and strongly curved posteriorly. The cercus of this species resembles that of N. panamensis .
