Background The present study is one in a series of planned studies aiming to catalogue the whole order Diptera in both Egypt and Saudi Arabia. New information All known Egyptian and Saudi Arabian conopid taxa are systematically catalogued in the present study. Three species are recorded herein for the first time from Saudi Arabia: Conops (Asiconops) elegans Meigen, 1804 and Thecophora atra (Fabricius, 1775) (Al-Baha region, south-western of Saudi Arabia), and Conops (Conops) quadrifasciatus De Geer, 1776 (Tabuk region, north-western of Saudi Arabia). Physocephala variegata (Meigen, 1924) is also recorded for the first time from Gebel Elba, the south-eastern triangle of Egypt. Considering that Gebel Elba in Egypt and Al-Baha in Saudi Arabia are affiliated to the Afrotropical Region, this is the first time Physocephala variegata and Thecophora atra have been recorded from the Afrotropical Region. An updated taxonomy, world and local distributions, dates of collection and some coloured photographs are provided.

埃及和沙特阿拉伯的Conopidae科（双翅目）

背景本研究是一系列计划研究中的一项，旨在对埃及和沙特阿拉伯的双翅目全目进行编目。新信息 本研究对所有已知的埃及和沙特阿拉伯的科诺科类群进行了系统编目。这里首次记录了来自沙特阿拉伯的三个物种：Conops (Asiconops) elegans Meigen, 1804 和 Thecophora atra (Fabricius, 1775)（Al-Baha 地区，沙特阿拉伯西南部）和 Conops (Conops)quadrifasciatus De吉尔，1776 年（沙特阿拉伯西北部塔布克地区）。Physocephala variegata (Meigen, 1924) 也首次在埃及东南三角区厄尔巴山被记录。考虑到埃及的Gebel Elba和沙特阿拉伯的Al-Baha都属于非洲热带地区，这是首次在非洲热带地区记录到Physocephala variegata和Thecophora atra。提供了更新的分类、世界和当地分布、收集日期和一些彩色照片。
