Orthetrum saegeri Pinhey, 1966
Eastern Mushroom Skimmer
Type locality: P.N.G[aramba]., DRC
Male is similar to O. julia by (a) frons at most with dorsal dark markings running down onto shields; (d) 1 row in radial planate, sum of cell-doublings 0-10 [0-14]; (c) all subcostal Ax dark; (f) Abd of normal proportions, shorter than Hw; (b) labrum always partly pale, although often with black; (e) Abd usually shorter than Hw (if longer, S4-6 with transverse bands); (g) S4-6 with pale transverse subapical bands or spots, S7-9 and usually S10 all dark. Cerci often all pale in young specimens. However, differs by (1) localised in forest; (2) Hw base only faintly yellow; (3) metepimeral carina not marked with black line; (4) hook of hamule broadened, hood-like, turned outward, with anterior excision at base.

Mostly standing and often temporary waters, but also streams, in open areas in forest, but sometimes shaded by gallery forest. Often with emergent vegetation, coarse detritus, a soft (like muddy) bottom, and probably blackwater. From 0 to 900 m above sea level, but possibly up to 1200.
