Abstract

Here we present a first record of Baetis vardarensis Ikonomov, 1962 in Croatian freshwater habitats. The species was collected in February and March 2020 at two sites in the Sava River. With this record, Croatian mayfly species richness increased to a total of 85 species. In addition, one of the species previously known only from literature, Kageronia fuscogrisea (Retzius, 1783), was confirmed in Croatia. The species was collected in the Rečica River, in March 2020. These results confirm that our knowledge about mayfly fauna in different regions of Balkan Peninsula is still incomplete and is increasing with systematic studies.
