This checklist summarises our present knowledge on Moroccan distribution of the water beetles of five families: Gyrinidae, Haliplidae, Noteridae, Hygrobiidae and Dytiscidae. It includes all available faunistic data based on material collected by the authors and from the private collections, as well as from the literature, PhD theses, and other unpublished sources covering a period between 1914 and 2018. The checklist of 112 species of 40 genera is presented with species distributions in Morocco and North Africa. Hydroglyphus major (Sharp, 1882) is reported for the first time from Morocco. Six species (Agabus dilatatus (Brullé, 1832), Hydroporus longulus Mulsant and Rey, 1861, H. nigrita (Fabricus, 1792), H. planus (Fabricius, 1782), Bidessus pumilus (Aubé, 1838) and Ilybius fuliginosus (Fabricius, 1792)) are excluded from the country’s fauna. A chorological analysis shows that most species are essentially Mediterranean (60%), whilst those whose distribution is wider in Palearctic (25%) or extends into Nearctic (9.29%) or Afrotropical regions (5.71%) are clearly less represented. This chorotype pattern is similar to that observed for other aquatic insects in the same study area.
