A revision of the Egyptian species of the genus Actorthia Kröber (Diptera: Therevidae: Phycinae).

The genus Actorthia Kröber, 1912 was described based on a single female from Tourrah (Egypt) and is revised for the first time since the original description. Actorthia khedivialis (Becker, 1912) is newly synonymized with A. frontata (Kröber, 1912) based on examination of the type specimens of both species recently discovered in the Cairo University Collection (Egypt) and Natural History Museum (Austria), respectively. Actorthia efflatouni Kröber, 1925 is confirmed as a synonym of A. micans (Kröber, 1923) and Actorthia olivierii (Macquart, 1840) is transferred to Phycus. Actorthia pulchella Kröber, 1927 is recorded in Israel for the first time. The three Egyptian species of Actorthia are diagnosed and illustrated along with colour images of the type specimens, and a key to the Egyptian species is included.

A review of the genus Tabanus Linnaeus, 1758 (Diptera: Tabanidae) from Egypt.

The Egyptian fauna of the genus Tabanus Linnaeus is reviewed. Only seventeen species are recognized instead of the previous 21. This is because six species have been removed as doubtful records, and an additional two species have been added (T. leucostonus Loew, 1858 (new record) and T. arenivagus Austen, 1920). A key to Egyptian species of Tabanus is included together with illustrations. Specimens examined and distributions are given for each species. The status of the six species doubtful to occur in Egypt is discussed.
