Africa: East African coastal regions from Somalia and Kenya, and delta of Zambezi River (Ref. 3498). Reported from Lake Rukwa basin and flood plains of Ruaha and lower Rufiji (Ref. 4967, 41366, 89002), but this species was never positively identified from Tanzania (Ref. 27292). The presence of this species in southern Africa also requires confirmation (Ref. 7248, 52193).
