Diagnosis. Neoacanthoneura magnipennis can be differentiated from most species of the genus by the combination of the frontal setae well-developed, the wing mostly dark brown with 3 hyaline marginal incisions and 2 round hyaline spots, by the vein R1 setulose only distal only to the apex of Sc, as well as crossvein dm-cu with its anterior end much more apical than its posterior end; it is similar in all these four characters to N. trupaneina , differing from it by having cell r2+3 entirely brown, including its basal part (with large hyaline spot posterior to the apex of vein Sc in N. trupaneina ); as well as the costal cell dark brown in the apical half (entirely hyaline in N. trupaneina ). The male of N. magnipennis has the costal vein produced anteriorly and covered with thickened setae along the apical half of the conspicuously elongate and widened pterostigma, as in the ♂ of N. apicalis , N. dryas and N. goniata .

Description. Head as figured by Kameneva & Korneyev (2010: Fig. 66.60) (as “ Aciuroides sp.”); length: height: width ratio 1: 1.2: 1.2; compound eye 1.4 times as high as long and frons 1.6 times as long as wide; face with blunt medial ridge, producing between antennae. Head setae and appendages as in N. euphrantina new species, except ocellar, postocellar and lateral vertical setae at most 0.3–0.4 times as long as medial vertical seta and almost as long as frontal seta; lateral vertical seta almost as long as postocular setae; flagellomere 1 more round, 1.2 times as long as wide; palpus narrower than, as long as flagellomere 1. Gena with 5–7 peristomal setae as long as frontal setae. Thorax and legs as described for N. euphrantina new species. Wing ( Fig. 45 ) elongate, 2.75 times as long as wide, with pattern with one large brown spot in apical 0.75 of its length, with basicostal and basal 0.6 of costal cell hyaline; basal 0.4 of pterostigma, cell r1 distal of R1 apex and cell m each with one hyaline incision extending into r2+3 and r4+5, correspondigly; apical portion of cell br and basal portion of r4+5 cell with round hyaline spot each. Costal vein produced anteriorly and covered with thickened setae along apical half of pterostigma, R1 elongate, reaching level of dm-cu apex and dorsally setulose beyond Sc apex only; vein R2+3 strongly undulate. Pterostigma conspicuously widened at middle, 1.5 times as long as costal cell. Vein M ratio m3: m2: m4 = 1: 1.4: 1.2. Wing length 3.9 mm.

Male abdomen as in N. euphrantina new species; surstyli moderately elongate, 3 times as long as epandrium, with 2 preapical prensisetae ( Fig. 82–83 ).

Female ( Fig. 57 ) similar to male; wing ( Fig. 46 ) with evenly arcuate costal vein and non-modified setulae on it, 2.6–3.0 times as long as wide; pattern similar to that in male; pterostigma 1.2–1.55 times as long as costal cell, dark brown in apical 0.6–0.7 of length; vein M ratio m3: m2: m4 = 1: 1.4–1.7: 1.2–1.45. Wing length 3.5–3.8 mm. Abdomen as described for N. apicalis new species, with tergites mostly dark brown or black except tergite 1 sometimes yellow; sternites yellow to brownish yellow; aculeus narrow, with blunt cercal unit, as on Fig. 85 ; three spherical spermathecae as on Fig. 86 .

Comments. Hendel (1914 b) described this species as a member of the family Tephritidae . It has not been included in the Catalog of Neotropical Otitidae ( Steyskal, 1968) . Later, Foote (1980) transferred it to the Ulidiidae (as Otitidae ) and noted that N. magnipennis is closely related to Aciuroides species.
