(Figs. 72–80, 110)
Comments and diagnosis. Similar to N. alamagna, N. nigra is generally black, but it can be easily distinguished from that species by having the wing shorter than the body; the spurious vein reduced, free in cell r1; the orbital and ocellar setae reduced; the proepimeral seta weak and the katepisternal seta absent. From the other species in the genus, N. nigra differs essentially in the black color of the body, and female with cerci rounded at apex and with very long basal ventral seta.
Description. Holotype female: Measurements (in mm): body length 11.8; head 1.35; abdomen 7.3; wing 10.6. Head (Figs. 74–76): Black, except outer contour of lunule pale brown (Fig. 74). Setae and setulae black. Head width-height ratio 1.28 (Fig. 74). Frons-head ratio 0.39 (Fig. 74). Frons width-height ratio 1.16 (Fig. 74). Ocelli-distance ratio 2.0 (Fig. 110). Ocellar triangle black almost indistinguishable of the color frons (Fig. 75), and extended posteriorly beyond posterior ocelli until vertex. Antenna dark brown (Fig. 76), except small portion on ventral surface and at base of first flagellomere, pale brown. Scape short, one-half as long as pedicel. First flagellomere 2.2 times longer than wide. Arista bare. Ocellar seta very short and thin, shorter than orbital seta. Postocellar seta present. Genal seta present and black. Postgenal seta absent. Palpus dark brown; obovate with apex rounded and distinctly wider than base (Fig. 76). Prementum brown (Fig. 76). Thorax (Figs. 72, 73): Scutum as long as wide; with two parallel and weak stripes of brown pollinosity, visible only from some angles. General color black, covered with thin and brownish pollinosity. Setae on thorax black and reduced. Postpronotal seta absent. Postsutural supra-alar seta very reduced, distinctly shorter and weaker than postalar and intra-alar setae. Postsutural dorsocentral seta very reduced, slightly more robust than setulae around it. Presutural supra-alar and katepisternal setae absent. Proepimeral seta very weak. Halter yellowish. Legs: Robust, fore femur slightly more swollen than mid and hind femora; fore tarsomeres distinctly more robust than mid and hind tarsomeres. Spine-like setae black. Fore leg dark brown, except trochanter and basal two-thirds of femur, pale brown. Mid and hind legs pale brown, except coxae and trochanters, and ventral apical spot on femora, brown. Pulvilli yellow. Fore femur with small spine-like antero- and posteroventral setae on apical third; spine-like setae similar in number and thickness. Mid coxa with one long black medial seta. Mid femur with spine-like antero- and posteroventral setae on apical half; spine-like posterodorsal setae without modifications, evenly spaced; ventral surface without hollow. Hind femur with spine-like antero- and posteroventral setae on apical two-thirds; dorsal seta absent. Wing (Figs. 73, 77): Shorter than body length (Fig. 73). Brown on anterior half and brownish on posterior half (Fig. 77). One spurious vein free in cell r1 (Fig. 77). Abdomen (Figs. 72, 73, 78): Entirely black, covered with black setulae. Syntergite 1‒2 2.0 times longer than tergite 3; basal three-fourths distinctly narrower than apical fourth (Fig. 78); with preapical set of five black setae on laterodorsal surface. Tergite 3 slightly longer than tergites 4 and 5; gradually wider than apex of syntergite 1+2 (Fig. 78). Tergites 4–5 gradually narrower than tergite 3(Fig. 78). Tergites 3–4 with row of apical black setae on laterodorsal and dorsal surfaces. Sternites 2–6 dark brown, covered with dark brown setae. Female terminalia (Figs. 79, 80): Not dissected, observed only externally: oviscape black, not measured. Taenia brown, as sclerotized as oviscape (Figs. 79, 80); not measured. Eversible membrane, sternite and tergite 8 not examined. Cerci 0.21 mm long; tip rounded and narrow, 0.035 mm in width, two-thirds of apical seta length (Fig. 79). Basal dorsal and ventral setae very long, similar in length (Fig. 80).
Variation. The paratypes from USNM are considerably longer than the holotype, reaching 13.0 mm in length. They may have some parts of the body paler than those in the holotype: frons and lunule pale brown; posterior third of anepisternum, anterior half of anepimeron, katepisternum and katatergite, pale brown; mid and hind legs yellowish brown, except the same brown marks found in the holotype.
Male. Unknown.
Type material. Holotype female, INBio: “ COSTA RICA. Prov. [Province] San Jose, Moravia\Zurqui de Moravia. 1600m. 20 FEB [February]‒13\ MAR [March] 2008. W. Porras [collector].

Etymology. The specific epithet is an adjective that refers to the black color of the body (Latin, nigra = black, dark).
