Redescription of two species of Ommatius wiedemann, with lectotype and paralectotype designations for Ommatius tenellus van der Wulp and range extension, and a replacement name for Ommatius tibialis Ricardo (Diptera: Asilidae)

The type series of Ommatius tenellus van der Wulp and O. tibialis Ricardo were examined and redescriptions are given for both species. A lectotype and paralectotypes are designated for O. tenellus, new records extend the range of the species across northern Africa, and illustrations of the terminalia are presented. Ommatius abdelkuriensis Scarbrough (new name) is proposed as a replacement name for O. tibialis.
