The discovery of new species with distinctively variable morphological characteristics overlaps with members of the closely related genus <em>Stenosathe</em> Lyneborg. <em>Stenosathe</em> is consequently synonymised with <em>Stenopomyia</em> with two species (<em>Stenosathe pilosa</em> Lyneborg and <em>Thereva brachycera</em> Loew) transferred to <em>Stenopomyia</em>. A third species from Turkmenistan (<em>Psilocephala pulchra</em> Kröber), currently placed uneasily in <em>Stenosathe</em>, is removed from the genus and placed as <em>incertae sedis</em> in Therevinae. A revised key to genera of Therevinae from the Ethiopian Region and Saharo-Arabian transition zone is presented along with a key to species of <em>Stenopomyia</em>.</p> MICHAEL E. IRWIN SHAUN L.
