Africallagma sinuatum (Ris, 1921)
Peak Bluet
Type locality: Kapiri, DRC
Diagnosis
Male is similar to A. quingentum by (a) size, Hw 18-20 mm; (b) postclypeus mostly blue, at most brownish or with limited basal black markings; (c) Fw Pt diamond-shaped, opposite borders roughly parallel and of similar length; (d) tibiae entirely pale or with thin, short dark stripes; (e) cerci sinuous, ending in short strongly hooked and tooth-like ventral process; (f) base of paraprocts much swollen, resulting in prominent inferior bulge. However, differs by (1) more widespread; (2) antehumeral stripes pale blue rather than green with maturity, like sides of thorax; (3) Pt blackish rather than pale brown with maturity; (4) dorsum S2 with continuous black band narrowed at apex, sometimes reduced to narrow triangular marking; (5) spines of paraprocts well-developed, black and acute.
