Gynacantha (B) victoriae (Pinhey, 1961)
Type locality: Entebbe, Lake Victoria, Uganda
Male is similar to the widely co-occurring G. bullata by (a) small size, Hw 35.0-44.0 mm; (b) pale legs with dark rings around the joints; (c) the absence of denticles in the posterior portion of the genital fossa border; and (d) the ventral carinae of S6-8 lacking denticles. However, has (1) the antennal sockets on the frons usually not blackened and thus contrasting with the black vertex; (2) broad blackish smears over the humeral sutures; (3) blue markings with maturity on the plate between Hw bases, dorsally on apex of S2 and laterally on base of S3; and (4) shorter cerci, 5.0-5.5 mm and less than 3x as long as the epiproct, distinctly shorter than S8-10 combined.

Standing and mostly temporary waters shaded by forest. Usually with coarse detritus and mostly a soft (like muddy) bottom. From 200 to 600 m above sea level, but possibly up to 1200.
