Morocco has a diverse bee fauna, but one that has also been relatively understudied in recent years. Here a revision of the species-rich genus Andrena is presented that reveals eleven new species for science and substantially improves our understanding of North African Andrena. From Morocco, Andrena (Aciandrena) semiadesus Wood, sp. nov., Andrena (Aciandrena) triangulivalvis Wood sp. nov., Andrena (Campylogaster) sparsipunctata Wood sp. nov., Andrena (Carandrena) hebescens Wood sp. nov., Andrena (Cnemidandrena) niveofacies Wood sp. nov., Andrena (incertae sedis) tenebricorpus Wood sp. nov., Andrena (Notandrena) acutidentis Wood sp. nov., Andrena (Poliandrena) breviceps Wood sp. nov., and Andrena (Poliandrena) farinosoides Wood sp. nov. are described and their ecology is discussed. Andrena (Aciandrena) astrella Warncke, 1975 is synonymised with Andrena (Aciandrena) fulica Warncke, 1974 syn. nov. The unknown female of Andrena (Nobandrena) ounifa Warncke, 1974, and the unknown male of Andrena (Poliandrena) guichardi Warncke, 1980 are described. Andrena (incertae sedis) gafsensis Wood sp. nov. from Tunisia is described due to its similarity to Andrena tenebricorpus. Andrena (Poecilandrena) nigriclypeus Wood sp. nov. from Algeria is also described as it was collected within 10 km of the Moroccan border. A further 18 species are recorded in Morocco for the first time. Andrena (Melandrena) nitida (Müller, 1776) and Andrena (Notandrena) nitidiuscula Schenck, 1853 are removed from the Moroccan list due to historic problems in the application of these names to Mediterranean taxa.

摩洛哥安德雷纳动物群（膜翅目、蜜蜂总科、安德雷纳科）的更新和修订，描述了 11 个新的北非物种


摩洛哥拥有多样化的蜜蜂动物群，但近年来对这一动物群的研究相对较少。这里对物种丰富的安德雷纳属进行了修订，揭示了十一个新的科学物种，并大大提高了我们对北非安德雷纳的了解。来自摩洛哥，Andrena (Aciandrena) semiadesus Wood, sp。 11 月，安德雷娜 (Aciandrena) triangulivalvis Wood sp。十一月，Andrena (Campylogaster) sparsipunctata Wood sp. 11 月，Andrena (Carandrena) hebescens Wood sp.十一月，安德雷娜（Cnemidandrena）niveofacies Wood sp。十一月，Andrena (incertae sedis) tenebricorpus Wood sp.十一月，Andrena (Notandrena) acutidentis Wood sp. 11 月，Andrena (Poliandrena) breviceps Wood sp.十一月，和安德雷娜（Poliandrena）farinosoides Wood sp。十一月进行了描述并讨论了它们的生态学。安德雷娜 (Aciandrena) astrella Warncke, 1975 与安德雷娜 (Aciandrena) fulica Warncke, 1974 同义词。十一月描述了 1974 年未知的雌性安德雷纳 (Nobandrena) ounifa Warncke 和 1980 年未知的雄性安德雷纳 (Poliandrena) guichardi Warncke。 Andrena (incertae sedis) gafsensis Wood sp.十一月来自突尼斯的描述是因为它与 Andrena tenebricorpus 相似。安德雷娜 (Poecilandrena) nigriclypeus Wood sp.十一月也被描述为来自阿尔及利亚，因为它是在摩洛哥边境 10 公里范围内收集的。摩洛哥还首次记录了 18 个物种。 Andrena (Melandrena) nitida (Müller, 1776) 和 Andrena (Notandrena) nitidiuscula Schenck, 1853 由于这些名称应用于地中海类群的历史问题而从摩洛哥名录中删除。
