Abstract In 2014–2019, we carried out an examination of Trichoptera of the Moulouya River basin in the Oriental, Fèz-Meknès and Drâa-Tafilalet regions of Morocco. Caddisflies of the territories of the High Plateau, the oriental Sahara and the eastern parts of the Rif, Middle Atlas and the High Atlas have been studied for the first time. We collected and identified 41 species. Rhyacophila sp. cf. intermedia/rougemonti McLachlan, 1868/McLachlan, 1880 (Rhyacophilidae); Hydropsyche sp. cf. exocellata Duföur, 1841 (Hydropsychidae) and Mesophylax aspersus hoggarensis Malicky, 1998 (Limnephlidae) are reported for the first time from Morocco. 21 species are recorded for the first time from Oriental Region and 13 species from Drâa-Tafilalet Region. For previously recorded species, we present additional distributional data. Additionally, we provide taxonomic notes on larvae of Athripsodes sp., Rhyacophila sp. and Mesophylax sp. cf. impunctatus McLachlan, 1884. We found a clear dominance of the Palearctic elements, typically Mediterranean, and a high rate of Ibero‐Maghrebian endemics in the Trichoptera fauna of northeastern Morocco. This chorotype pattern is similar to patterns observed for other aquatic insects in the same study area.

来自摩洛哥东北部的石蛾（昆虫纲：毛翅目）动物群的新数据以及关于生物钟学的说明

摘要 2014-2019 年，我们对摩洛哥东部、非斯-梅克内斯和德拉-塔菲拉莱特地区的穆卢亚河流域的毛翅目进行了检查。首次研究了高原、东方撒哈拉和里夫东部、中阿特拉斯和高阿特拉斯地区的石蛾。我们收集并鉴定了 41 个物种。Rhyacophila sp. 参见 intermedia/rougemonti McLachlan, 1868/McLachlan, 1880 (Rhyacophilidae)；Hydropsyche sp. 参见 exocellata Duföur, 1841 (Hydropsychidae) 和 Mesophylax aspersus hoggarensis Malicky, 1998 (Limnephlidae) 是摩洛哥首次报道。东方地区首次记录到 21 种，Drâa-Tafilalet 地区首次记录到 13 种。对于以前记录的物种，我们提供了额外的分布数据。此外，我们提供有关 Athripsodes sp., Rhyacophila sp. 幼虫的分类注释。和 Mesophylax sp。参见 impunctatus McLachlan，1884 年。我们发现古北元素明显占主导地位，典型的地中海元素，以及摩洛哥东北部毛翅目动物群中伊比利亚-马格里布特有的高比例。这种 chorotype 模式类似于在同一研究区域观察到的其他水生昆虫的模式。
