A new population of Dytiscus lapponicus Gyllenhal, 1808 from Belgium with notes on the distribution and ecology of the species (Coleoptera: Dytiscidae)

During an eco-hydrological study on the aquatic habitats in the nature reserve ‘Ophovenerheide’ Dytiscus lapponicus Gyllenhall, 1808 was encountered in two small oligotrophic lakes. The species was only known from two populations in the province of Antwerpen. This new record also represents the Southernmost confirmed population of D. lapponicus in Europe, with exception of the population of D. lapponicus disjunctus in the Maritime Alps. In this article the distribution and the habitat in Belgium is discussed and the possible threats for the Belgian populations are given.
