Male is similar to A. elongatum by (a) spine of paraprocts reaches well beyond its bulge and usually also beyond tip of cerci; (b) cerci with dorsal border markedly excised (lateral view). However, differs by (1) ranging from Katanga to Angola and South Africa; (2) humeral stripe usually reduced to hairline for much of their length, much narrower than antehumeral; (3) cerci with dorsal border barely excised.
