Africallagma glaucum (Burmeister, 1839)
Swamp Bluet

Type locality: Cape Province, South Africa

Diagnosis

Male is similar to A. vaginale by (a) postclypeus black; (b) Fw Pt diamond-shaped, opposite borders roughly parallel and of similar length, pale brown to black; (c) tibiae with prominent black stripes along almost entire length (d) cerci at most slightly longer than paraprocts (e) spine of paraprocts does not reach beyond bulge (at most slightly) or tip of cerci; cerci with dorsal border not or weakly excised; (f) base of paraprocts much swollen, resulting in prominent inferior bulge. However, differs by (1) being restricted to open landscapes; widespread; (2) metapleural suture with black dot, rather than prominent black stripe, at dorsal end; (3) Abd stout rather than slender, wing tips reach to end of S6; (4) S8-9 usually largely to entirely blue; (5) ventral process of cerci broad rather than slender, slightly separated from broadly rounded apex (best seen in caudal view).
