C. picteti is widely distributed species in the Europe, but, due to the stenovalent character of the species, as well as destruction of relevant aquatic habitats, it has been characteri-zed as rare and endangered species. This finding indicates, once again, that Serbian may-fly (Ephemeroptera) fauna is still not completely known and detailed surveys are needed. Serbian streams are renowned for their diverse fauna, although specific knowledge about the taxa inhabiting them is scarce, that include mayfly fauna too. Insect fauna of small streams of mountainous region of Serbia (north from the Danube) are especially diverse and reports of new species for fauna of Serbia are expected. The first record of Choroter-pes picteti (Eaton, 1871) for Serbia is reported in this research.
