Pseudagrion (A) thenartum Fraser, 1955
Orange Slim Sprite
Type locality: Uele, Bambesa, DRC
Male is similar to P. simplicilaminatum by (a) slender forest species, ranging from DRC to W; (b) antehumeral stripe at least as broad as half-width of mesepisternum, constricted or broken near dorsal end; (c) at least tibiae and often femora largely pale; (d) cerci not branched in lateral view. However, differs by (1) larger size, Hw 21-24 mm; (2) thorax, including antehumeral stripe, and postocular spots orange (yellow when preserved), rather than blue; (3) Pt yellow, rather than black; (4) cerci club-shaped, rather than awl-shaped, with rounded apices.

Mostly headwater streams, but also seeps, springs and possibly standing waters, shaded by forest. Usually with coarse detritus and/or a sandy bottom and probably especially calmer sections (like pools) with emergent vegetation. From 200 to 700 m above sea level.
