Orthetrum machadoi Longfield, 1955
- scientific: O. rhodesiae Pinhey, 1961
- vernacular: Machado's S. (Su, Sa, Ta, RL)
Type locality: Dundo, Lunda District, Angola
Male is similar to O. lusinga by (a) size, Hw 24-31 mm; (b) labium all pale, rarely black on central lobe; (c) 1 row in radial planate, sum of cell-doublings 0-10 [0-14]; (d) usually all (at least proximal) subcostal Ax pale; (e) Pt not swollen, usually 12.5% of Hw length or less; (f) metepimeral carina not marked with black line; (g) space between hook and lobe of hamule usually wide; (h) hook of hamule broader, turned out- or backward and with curved and/or excised anterior border; (i) at least S4-7 with pale longitudinal streaks, at most S9-10 all dark, although marking on S8 can be tiny. Cerci always at least partially dark. However, differs by (1) being widespread; (2) hook of hamule with convex rather than concave anterior border, pointed and backward-turned tip well-separated from lobe; (3) S6-8 broadly black laterally, S9-10 largely black rather than brown.

Mostly standing and probably often temporary waters, but also streams and possibly headwaters, seeps and springs, in open landscapes, but sometimes shaded by gallery forest. Usually with emergent vegetation and often a soft (like muddy) bottom. From 0 to 1900 m above sea level, but mostly between 900 and 1800.
