The Macaronesian species of the muscid genus Helina are revised. The genus is represented in the Canary Islands by 9 species, in Madeira by 7 species, and in the Azores Islands by 1 species. Four species, one divided in two subspecies, are endemic to the Canary Islands: Helina grancanariae sp. nov. (Gran Canaria), H. obscurisquama obscurisquama (Stein) (Tenerife, La Gomera), H. obscurisquama pseudonivalis (Santos Abréu) ssp. rev. (La Palma), H. rufitibialis Hennig (Tenerife, La Gomera, La Palma) and H. santosabreui sp. nov. (La Gomera, La Palma). The following three species are endemic to Madeira: Helina atlantica (Tiensuu), H. lundbladi Tiensuu and H. vilissima Hennig. Existing records of Helina almeriensis (Strobl) and H. quadrum (Fabricius) from the Canary Islands are considered as misidentifications. An identification key to males and females concludes the species accounts. Finally, a description is given of the previously unknown male sex of the endemic Madeiran Spilogona maderensis Michelsen.
对麦哲伦群岛蝇科昆虫 Helina 属进行修订。该属在加那利群岛有 9 种，在马德拉群岛有 7 种，在亚速尔群岛有 1 种。其中有 4 种，1 种分为两个亚种，是加那利群岛特有的：新种格兰卡纳里亚蝇 Helina grancanariae sp. nov.（大加那利岛）、Stein 命名的暗斑异蝇 Helina obscurisquama obscurisquama（特内里费岛、戈梅拉岛）、Santos Abréu 命名的暗斑异蝇 Helina obscurisquama pseudonivalis ssp. rev.（拉帕尔马岛）、Hennig 命名的红腿异蝇 Helina rufitibialis（特内里费岛、戈梅拉岛、拉帕尔马岛）和 Santos Abréu 命名的新种圣塔克鲁兹蝇 Helina santosabreui sp. nov.（戈梅拉岛、拉帕尔马岛）。以下三种是马德拉群岛特有的：大西洋异蝇 Helina atlantica (Tiensuu)、Lundblad 命名的伦布迪异蝇 Helina lundbladi 和 Hennig 命名的极细异蝇 Helina vilissima。加那利群岛原有的 Helina almeriensis (Strobl) 和 H. quadrum (Fabricius) 的记录被认为是错误鉴定。雌雄鉴别特征的关键在于男性和女性的特征。最后，描述了马德拉群岛特有的 Spilogona maderensis Michelsen 未知的雄性。
