Drusus chrysotus (Rambur, 1842) (Trichoptera: Limnephilidae: Drusinae): a new caddisfly species in the Croatian fauna

Drusus chrysotus is a cold water stenotherm species inhabiting spring reaches and headwaters of mountain streams. It has a disjunct distribution range covering mountain ranges across central Europe, and has been recorded for the first time in Croatia now, in the Gorski kotar region, thus extending its distribution range to the Dinaric Western Balkan ecoregion (sensu Illies, 1978). D. chrysotus has been collected in the spring of the river Dobra which is heavily impacted by human activity. Due to the specific aquatic insects’ fauna of this spring, conservation and prevention of further habitat alteration of this section of the river Dobra should be a priority for the local community.
