Key to species of Acidogona

1. Scutellum entirely microtrichose. Wing of female ( Figs. 30–31, Foote et al. 1993, fig. 110) with hyaline spots relatively large, spot at apex of vein R 2+3 usually extending to posterior half of cell r 2+3, cell r 4+5 with at most 3 hyaline spots distal to crossvein dm-cu. If wing of male without hyaline marks in cell dm ( Fig. 32), male abdominal tergites 3–5 without brown markings ........................................................................................................................................ 2

- Scutellum nonmicrotrichose except sometimes on lateral and apical margins. Wing of female ( Foote et al. 1993, fig. 528) with hyaline spots relatively small, spot at apex of vein R 2+3 not extending to posterior half of cell r 2+3, cell r 4+5 with at least 4 small hyaline spots distal to crossvein dm-cu. Wing of male ( Foote et al. 1993, fig. 529) without hyaline marks in cell dm. Male abdominal tergites 3–5 with 2 pairs of dark brown spots. Western Canada & USA......... .......................................................................................................................................................... dichromata (Snow)

2. Wing of female ( Foote et al. 1993, fig. 110) with separate hyaline spots medially in cells br, dm and cu 1 and distally in cells r 2+3, r 4+5 and m; marginal hyaline marks in cell r 1 often not extending to vein R 4+5; and pterostigma usually with subapical yellowish to hyaline spot. Wing of male with hyaline spots in cell dm. Male abdomen with at least 1 pair of brown spots on tergites 3–5. Eastern Canada & USA............................................................. melanura (Loew)

- Wing of female ( Figs. 30–31) with hyaline band from cell br to posterior wing margin in cell cu 1 and oblique subapical hyaline band across most of cells r 4+5 and m, sometimes fusing with marginal spot in cell r 2+3; marginal hyaline marks in cell r 1 both large, extending to vein R 4+5; and pterostigma entirely brown. Wing of male ( Fig. 32) without hyaline marks in cell dm. Male abdomen at most with pair of brown spots on syntergite 1+2.
