Pseudagrion (B) glaucoideum Schmidt in Ris, 1936
Type locality: Congo, no locality data available.
Male is similar to P. isidromorai by (a) ranging from W Uganda and N Zambia to W Africa; (b) size, Hw 19-23 mm; (c) face green or blue, sometimes yellowish; (d) dorsum of S2 with double-pronged marking, like U or Y, or largely black, usually with blue centre; (e) S8-9 seldom with narrowly black apical border, often all blue; (f) apex of penis weakly to strongly concave; (g) upper branch of cerci hooked, but inner border of lower branch smooth- lower branch of cerci long, finger-like; (h) paraprocts never with dorsal knob (lateral view). However, differs by (1) humeral sutures and vertex always with fragmented black markings, rather than often being extensively black; (2) lower border of cerci more straight, rather than round and bulging; (3) penis with long apical lobes with deep notch between them, rather than having a weakly concave, squarish apex.

Mostly rivers, but also streams, in open areas in forest or shaded by gallery forest. Usually with emergent vegetation and often a sandy and/or soft (like muddy) bottom, probably especially calmer sections. From 0 to 1700 m above sea level.
