Beetles play an important role in agrosystems as bioindicators of quality, ecology, conservation, and soil characteristics. The Coleoptera of agrosystems in Morocco are poorly known. To contribute to the knowledge of beetles in this country we conducted a survey in a region of North-West Morocco between 2019 and 2020. The inventory was carried out using several types of traps. We identified 54 species belonging to 14 families, 20 subfamilies, and 18 tribes. The most abundant family was Carabidae, with 24 species, and the most dominant subfamily was Harpalinae, with 19 species. This work provides the first checklist of coleopteran fauna associated with agrosystems in North-West Morocco. We provide an identification key of subfamily and tribe, and update information on the distribution of the beetles identified. Checklist dataset published through GBIF (Doi: 10.15470/ohymvn)

The Carabidae play an increasing role in biodiversity conservation and ecological monitoring, making a faunistic update all the more necessary. Carabids, however, are poorly known considering their diversity in the world. Also known as ground beetles, they are the fourth most diverse group within the Coleoptera, but the amount of published data sets from Morocco is disproportionately small; many species and regions have yet to be well researched. In an effort to fill this gap, we studied the faunistic composition of the carabidae in the north-west of Morocco between spring 2019 and summer 2020 at three different habitat types using two types of traps. Here we present new data on some rare and poorly known Carabidae in Morocco: Pterostichus (Sterocorus) globosus ssp. globosus (Fabricius, 1792), Poecilus (Parapedius) decipiens ssp. decipiens (Waltl, 1835), Harpalus neglectus alluaudi (Antoine, 1922), Graniger cordicollis (Audinet Serville, 1821), Brachinus (Brachinus) efflans (Dejean, 1830), Brachinus (Brachinidius) angustatus (Dejean, 1831), Carabus (Macrothorax) rugosus ssp. rugosus (Fabricius, 1792) and Siagona dejeani (Rambur, 1838). Our results contribute to the knowledge of the Moroccan carabid fauna by introducing eight new localities of terrestrial insects that were poorly unknown and infrequently reported in Morocco over the past 20 years.
