Morphological features of larvae of Drusus osogovicus Kumanski, 1980 (Insecta, Trichoptera) from the Republic of North Macedonia, DNA barcoding of the species and notes on its ecology and distribution

The Balkan endemic caddisfly species Drusus osogovicus Kumanski, 1980 that was previously known only from Bulgaria recently reported the Republic of North Macedonia as well. However, all data on presence included adult specimens larval stage remained unknown. In following study we present first description based morphological characters. order to prove conspecificity between larvae and adults, DNA barcoding also conducted. Furthermore, lists crucial diagnostic characters in D. well information distribution ecological preferences are provided.
