Aciagrion rarum (Longfield, 1947)
Tiny Slim

Type locality: Lunda, Angola

Diagnosis

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.
