Blue Wisp

Type locality: Sangévé, Angola

Diagnosis

Male is similar to A. bumhilli by (a) very small size, Hw 9-10 mm; (b) labrum pale, or dark with pale border; (c) cerci longer than S10 with long, finger-like process; (d) paraprocts much shorter than cerci, ending in single denticle. However, differs by (1) ranging from Angola to N Botswana, N Namibia and N Zambia; (2) antehumeral stripes present; (3) costa above Hw Pt widened, with white pruinosity; (4) S10 not swollen, smaller than S9; (5) cerci parallel-sided with broadly rounded apex in dorsal view.
