Several field surveys at 391 freshwater localities between 1985 and 2019 were undertaken in Morocco. Altogether, our field studies identified 67 species belonging to three genera (Hydraena, Limnebius, and Ochthebius), and representing 85.89% of the Hydraenidae fauna of the country. The species Hydraena exarata Kiesenwetter, 1866 is reported for the first time from Africa, and Ochthebius (Ochthebius) thermalis Janssens, 1965 and O. (Ochthebius) grandipennis Fairmaire, 1879 are here recorded for the first time from Morocco. These findings increased the number of Moroccan Hydraenidae to 78. Ochthebius semisericeus Saint-Claire Deville, 1914 and O. viridis Peyron, 1858 are excluded from the Moroccan fauna. Furthermore, the checklist presented in this work includes 15 Moroccan endemic, 19 Ibero-Maghrebian endemic and 8 Maghrebian endemic species. A biogeographical analysis shows that the Hydraenidae from Morocco are essentially Mediterranean (89.74%), while the Palaearctic elements (7.70%) and the species with wider distributions (2.56%) are less represented, highlighting the general limited dispersion capability of Hydraenidae compared to other water beetle families. The present study can serve as the basis for future progress in the knowledge of the Moroccan Hydraenidae.
1985 年至 2019 年期间，在摩洛哥的 391 个淡水地点进行了多次实地调查。我们的实地研究总共确定了 67 种属于三个属（Hydraena、Limnebius 和 Ochthebius）的物种，占该国 Hydraenidae 动物区系的 85.89%。Kiesenwetter 于 1866 年首次报道的物种 Hydraena exarata 来自非洲，而 Janssens 于 1965 年首次记录的 Ochthebius (Ochthebius) thermalis 和 Fairmaire 于 1879 年首次记录的 O. (Ochthebius) grandipennis 来自摩洛哥。这些发现使摩洛哥的 Hydraenidae 物种数量增加到 78 种。Ochthebius semisericeus Saint-Claire Deville, 1914 和 O. viridis Peyron, 1858 从摩洛哥动物群中排除。此外，本工作中的清单包括 15 种摩洛哥特有种、19 种伊比利亚-马格里布特有种和 8 种马格里布特有种。生物地理分析表明，摩洛哥的 Hydraenidae 主要属于地中海（89.74%），而古北界元素（7.70%）和分布范围更广的物种（2.56%）则较少，这突出了与其他水甲虫科相比，Hydraenidae 的一般有限扩散能力。本研究可以为未来摩洛哥 Hydraenidae 的知识进步提供基础。
