The taxonomy and distribution of the genus Hybos Meigen in the Palaearctic Region is reviewed with a special reference to the European fauna. Twenty-three species have been recorded from the Palaearctic, of which only four species are known from Europe. We describe two new species, H. andradei sp. nov. (Portugal) and H. mediasiaticus sp. nov. (Middle Asia). The status of two previously considered doubtful species of Hybos are validated: H. striatellus Villeneuve, 1913 (Algeria) and H. vagans Loew, 1874 (the Caucasus). Both species are re-described, and the lectotype of H. striatellus is designated. A key to species of Hybos from the western Palaearctic is compiled. Numerous new data on distributions of H. culiciformis (Fabricius, 1775), H. femoratus (Müller, 1776), H. grossipes (Linné, 1767) and H. vagans are given. Hybos culiciformis is recorded for the first time from Algeria, Byelorussia, Croatia, Cyprus, Lebanon, and Portugal; H. femoratus-from Estonia, Georgia (including Abkhazia), Kazakhstan, Mongolia and Ukraine; H. grossipes-from Byelorussia, Estonia, Kazakhstan, Latvia, Mongolia, Ukraine; H. vagans-from Armenia, Azerbaijan, Georgia (including Abkhazia), Russia, Turkey. The variation of some characters in H. culiciformis is discussed and is confirmed for Portugese specimens by COI barcoding. Female postabdominal structures are examined and described for H. andradei sp. nov., H. culiciformis, H. femoratus, H. grossipes, H. mediasiaticus sp. nov., and H. striatellus. Possible relationships of the West-Palaearctic species are discussed. A check-list of Hybos from the Palaearctic Realm is provided.
本文回顾了古北区的歧大蚊属（Hybos Meigen）的分类及分布情况，特别提及了欧洲的动物区系。古北区已记录有23个物种，其中欧洲仅知4种。我们描述了两个新物种，安德拉德歧大蚊（H. andradei sp. nov.）（葡萄牙）和中亚歧大蚊（H. mediasiaticus sp. nov.）（中亚）。确认了两个之前被认为存疑的歧大蚊物种的地位：条纹歧大蚊（H. striatellus Villeneuve，1913）（阿尔及利亚）和游荡歧大蚊（H. vagans Loew，1874）（高加索地区）。对这两个物种进行了重新描述，并指定了条纹歧大蚊的选模标本。编制了一份西古北区歧大蚊属物种检索表。给出了关于库蚊状歧大蚊（H. culiciformis (Fabricius, 1775)）、股胫歧大蚊（H. femoratus (Müller, 1776)）、粗足歧大蚊（H. grossipes (Linné, 1767)）和游荡歧大蚊分布的大量新数据。库蚊状歧大蚊首次在阿尔及利亚、白俄罗斯、克罗地亚、塞浦路斯、黎巴嫩和葡萄牙被记录；股胫歧大蚊在爱沙尼亚、格鲁吉亚（包括阿布哈兹）、哈萨克斯坦、蒙古和乌克兰被记录；粗足歧大蚊在白俄罗斯、爱沙尼亚、哈萨克斯坦、拉脱维亚、蒙古、乌克兰被记录；游荡歧大蚊在亚美尼亚、阿塞拜疆、格鲁吉亚（包括阿布哈兹）、俄罗斯、土耳其被记录。讨论了库蚊状歧大蚊某些特征上的变异，并通过细胞色素氧化酶亚基I（COI）条形码对葡萄牙标本进行了确认。对安德拉德歧大蚊、库蚊状歧大蚊、股胫歧大蚊、粗足歧大蚊、中亚歧大蚊和条纹歧大蚊的雌性腹部后部结构进行了检查和描述。讨论了西古北区物种可能的亲缘关系。提供了一份古北区歧大蚊属的名录。
