This small species, widespread throughout sub-Saharan Africa, just touches the Zambezi and eastern Kavango regions. While it is inconspicuous, it occurs in locks and is unlikely to be mistaken for any other species. It occupies edge habitat often near water over an area of 3,700 km2, of which 40% occurs within conservation areas of the Nkasa Rupara (Mamili) National Park and the Mahango area of the Bwabwata National Park. This explains its presence along the Okavango, Zambezi and Kwando rivers in Namibia. It has low reporting rate in Namibia of 6%, despite probably being resident here.
