Aciagrion rarum (Longfield, 1947)
Type locality: Lunda, Angola
Male is similar to A. gracile and A. macrootithenae by clearly longer and larger paraprocts than cerci, with dorsal and very basal tooth and apex swollen and rounded (lateral and caudal view). However differs by (1) smaller size, Hw 12-13 mm; (2) cerci with triangular ventral process extending below its apex, rather than being closer to base; (3) paraprocts 2x as long as cerci.

Not known, but possibly standing and often temporary waters shaded by gallery forest. Inferred to occur at around 600 m above sea level, but possibly up to 1300.
