Diagnosis. Neoacanthoneura geomyzina is very similar to N. euphrantina in having vein R1 setulose over its whole length and wing pattern (consisting of a large apical spot, h-shaped bifurcated discal crossband and wide subbasal crossband) differing from it by the ventral margin of the face strongly produced anteriorly (in male), palpus very wide, flattened and white (in male), the apical spot either entirely separated by the hyaline crossband (in male) or at most touching discal crossband along the vein R4+5 (in female). The female of N. geomyzina has the dark apical spot entirely brown, with the proximal margin forming a conspicuous step along the vein R4+5, whereas in N. euphrantina the apical dark spot includes a hyaline spot in r4+5 and usually in r2+3.

Description. Head ( Fig. 6 View FIGURES 1 – 7 ) yellow, with whitish face, reddish frons and sometimes brownish occiput; length: height: width ratio 1: 1.05: 1.3; compound eye 1.3–1.4 times as high as long and frons 1.6–1.7 times as long as wide; face saddle-like, with ventral margin strongly produced anteriorly in male. Head setae and appendages as in N. euphrantina , except palpus of male white, extremely widened, as wide as long and 1.5 times as wide and as long as flagellomere 1. Thorax and legs as described for N. euphrantina . Wing ( Figs. 43 View FIGURES 41 – 48 ) elongate, 3–3.1 times as long as wide, with pattern similar to that in N. euphrantina , but large apical spot entirely separated from h-like discal crossband. Costal vein, R1 and vein R2+3s as in N. euphrantina . Pterostigma very narrow, 0.8–0.9 times as long as costal cell. Vein M ratio m3: m2: m4 = 1: 2.2–2.5: 3–3.4. Wing length 3.15–3.5 mm.

Male abdomen as in N. euphrantina ; epandrium superficially similar to that in N. euphrantina , not dissected.

Female similar to male; face ventral margin moderately produced and not exceeding level of fronto-facial angle anteriorly; palpus of common shape, as in other species of Neoacanthoneura ; wing wider than in male, 2.7– 2.8 times as long as wide; pattern similar to that in male, but hyaline spots forming distalmost hyaline crossband (distal of R1 apex) usually shifted proximally so apical spot partly touching h-like dark crossband along R4+5 vein; cells r2+3 and r4+5 inside apical brown spot entirely dark, without hyaline spots; other crossbands as described for female of N. euphrantina ; pterostigma 0.75–0.95 times as long as costal cell, dark brown in apical 0.5–0.7 of length; vein M ratio m3: m2: m4 = 1: 7–8: 5–6.5. Wing length 3.3–3.8 mm. Abdomen as described for N. apicalis , with tergites mostly dark brown or black except tergite 1 sometimes yellow; sternites yellow to brownish yellow; female terminalia not dissected, aculeus externally similar to that in N. euphrantina .

Etymology. The name reflects similarity of the wing pattern to that in some species of the genus Geomyza (Opomyzidae) .
