Abstract

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 now been recorded for the first time in Croatia, in the Gorski kotar region, thus extending its distribution range to the Dinaric Western Balkan ecoregion (sensu Illies, 1978). D. chrysotus was collected at the spring of the Dobra River, which is heavily impacted by human activity. Due to the specific aquatic insect fauna of this spring, conservation and prevention of further habitat alteration of this section of the Dobra River should be a priority for the local community.
