Bombyliidae (bee flies) are one of the largest dipterous families in Saudi Arabia with 116 hitherto recorded species. Larvae of these flies are predators or parasitoids of different stages of other insects in the orders Orthoptera, Neuroptera, Coleoptera, Lepidoptera, Hymenoptera and Diptera, in addition to spiders (order Araneae, class Arachnida), so they have potential use as biological control agents for pests belonging to these orders. In the present study, the list of Saudi Arabian fauna of bee flies (family Bombyliidae) is supplemented with seven new records in five genera and four subfamilies. The newly recorded species are Parageron lutescens (Bezzi, 1925) [Usiinae], Phthiria salmayensis Efflatoun, 1945 [Phthiriinae], Heterotropus bisglaucus Bezzi, 1925, Heterotropus maculiventris Bezzi, 1925, Heterotropus xanthothorax Efflatoun, 1945 [Heterotropinae], Anthrax greatheadi El-Hawagry, 1999, and Desmatoneura brevipennis (Bezzi, 1924) [Anthracinae]. World and local distributions of recorded species, diagnoses, remarks on feeding behaviors and some colored photographs were provided. The present study supplements the bee fly fauna (family Bombyliidae) in Saudi Arabia with seven new records. This brings the total number of bee fly species in the country into 123 species classified in 40 genera, 12 tribes and 10 subfamilies.

来自沙特阿拉伯的蜜蜂蝇（Bombyliidae，双翅目）的七项新记录

Bombyliidae（蜂蝇）是沙特阿拉伯最大的双翅目科之一，迄今已记录了 116 个物种。这些苍蝇的幼虫是直翅目、神经翅目、鞘翅目、鳞翅目、膜翅目和双翅目中其他昆虫不同阶段的捕食者或寄生蜂，此外还有蜘蛛（蜘蛛目，蛛形纲），因此它们具有作为生物防治剂的潜在用途对于属于这些目的害虫。在本研究中，沙特阿拉伯蜜蜂蝇（Bombyliidae）动物群列表补充了五个属和四个亚科的七个新记录。新记录的物种是 Parageron lutescens (Bezzi, 1925) [Usiinae], Phthiria salmayensis Efflatoun, 1945 [Phthiriinae], Heterotropus bisglaucus Bezzi, 1925, Heterotropus maculiventris Bezzi, 1925, Heterotropus xanthothorax Efflatoun, 1945 [Heterotropinae]，Anthrax greatheadi El-Hawagry，1999，和 Desmatoneura brevipennis (Bezzi，1924) [Anthracinae]。提供了记录物种的世界和当地分布、诊断、摄食行为评论和一些彩色照片。本研究以七项新记录补充了沙特阿拉伯的蜂蝇动物群（家蝇科）。这使该国的蜂蝇物种总数分为 40 个属、12 个部落和 10 个亚科的 123 个物种。
