Proteininae Erichson, 1839

Proteinus brachypterus (1.5-1.9 mm) is a common beetle with a wide range in the western Palaearctic region which will be searched in any moist decaying organic matter. We noted 2,447 specimens in only 21 1 x 1 km grids (Annex) with the comment that this beetle can be locally very numerous. On 30 March 2017, the seventh author captured 1,958 individuals within an hour, using a vehicle-mounted car-net, in a mixed forest in Lanaken (FS8345).
