Heliaeschna ugandica McLachlan, 1896
Type locality: Uganda, no locality data available.
Male is similar to H. sembe by (a) moderate size, Hw 38-46 mm; (b) frons completely dark or with stemmed T-shaped mark; (c) wing bases usually clear; (d) anal triangle of 3 cells; (e) anal loop of 7-14 cells; (f) cerci wide, blade about 3x as wide as stalk, and without basal thickening; (g) widest point of blade of cerci at about mid-length of blade; (h) epiproct 45-55% length of cerci. However, differs by (1) metapleural and humeral bands absent; (2) 20-25 rather than 26-30 Ax in Fw, but occasionally as many as 27. See diagnosis of very similar H. trinervulata.

Not known well, but probably temporary standing waters shaded by forest. Probably often with coarse detritus and a soft (like muddy) bottom. From 1100 to 1300 m above sea level, but possibly down to sea level.
