Diagnosis. Neoacanthoneura trupaneina is similar to N. magnipennis in the combination of the presence of frontal setae, the wing mostly dark brown with hyaline marginal incisions and round hyaline spots, the R 1 setulose distally of Sc, and the crossvein dm-cu with its anterior end much apical than its posterior end. It differs from N. magnipennis by having cell r 2 + 3 hyaline in its basal part; as well as the costal cell entirely hyaline. The male of N. trupaneina does not differ from f from female either by the shape of the costal vein, or by shape of setulae on it.

Description. Head as in N. magnipennis ; length: height: width ratio 1: 1.3: 1.35; compound eye 1.4 times as high as long and frons 1.4 times as long as wide; face with blunt medial ridge, not produced between antennae in the holotype, but more acute and produced in non-type specimen from Turrialba ( Costa Rica). Head setae and appendages as in N. magnipennis ; flagellomere 1 elongate, 1.6 times as long as wide; palpus narrow, as long as flagellomere 1. Thorax and legs reddish yellow to brown, as in N. euphrantina new species. Wing ( Figs. 47–48 ) elongate, 2.75 times as long as wide, with pattern with large brown spot in apical 0.6 of its length, and pale brown small spots in cells r 1 and br bordering to R 2-5 fork; basicostal and entire costal cell hyaline; basal 0.4 of pterostigma, cell r 1 at dm-cu level and cell m each with one hyaline incision extending into r 2 + 3 and r 4 + 5, correspondingly; apical portion of cell br and basal portion of r 4 + 5 cell with round hyaline spot each; cell dmwith hyaline basal half, narrow brown bar basal of r-m level, subquadrate hyaline spot posterior of r-m and brown apical 0.3 of cell length; in holotype, cell apex with hyaline streak along crossvein dm-cu; cell cua 1 with brown apical 0.2. Costal vein evenly arcuate, not produced anteriorly, covered with normal setae; R 1 apex proximally of dm-cu base level and vein R 1 dorsally setulose on apical half only; vein R 2 + 3 strongly undulate. Pterostigma narrow, 0.9 times as long as costal cell. Vein M ratio m 3: m 2: m 4 = 1: 1.8: 0.85. Wing length 2.9 mm.

Male abdomen as in N. magnipennis . Terminalia not dissected, externally like in the mentioned species.

Female ( Fig. 48 ) similar to male; wings shriveled in all examined specimens, measurements not available; pattern similar to that in male; pterostigma 0.75–0.85 times as long as costal cell, dark brown in apical half; vein M ratio m 3: m 2: m 4 = 1: 1.5: 1.0. Wing length 2.8 –3.0 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; oviscape almost as long as 4 posteriormost tergites combined; terminala not dissected.

Comments. In 2000, I examined a specimen from Turrialba, Costa Rica that is somewhat different in the head shape and minor details of the wing pattern; only pencil draft figures of this specimen were available while preparing this paper, and I have not seen any additional material from Central America, so I do not include this specimen in the type series, and identify it as N. trupaneina only provisionally.

Etymology. The name reflects similarity of the wing pattern to that in some species of the genus Trupanea , especially those formerly assigned to Urelliosoma ( Tephritidae ).
