Paragomphus lacustris (Karsch, 1890)
Type locality: Lake Tanganyika, Tanzania/Zambia
Male is similar to P. lacustris by (a) occcurring at streams, rivers and lakes in tropical Africa; (b) labrum pale, at most vaguely darkened at base; (c) thorax yellow to green with more prominent brown to black markings, that on metastigma ends just dorsal of it; (d) Pt brown, not contrasting with black veins; (e) S8-9 with broad foliations; (f) cerci less slender, apex blunt, without or with one tooth; (g) cerci without distinct ventral ridge; epiproct about 1/3 as long as cerci. However, differs by (1) relatively smaller size, Hw 21-25 mm; (2) dark markings fainter, not defining clear pale postdorsal and antehumeral stripes; (3) cerci thicker, apex with prominent black ventral tooth.

Not known, but probably large lakes in open landscapes. Probably often with a sandy bottom. From 500 to 1000 m above sea level.
