Based on the results of a recent faunistic study, an annotated list of species of the suborder Auchenorrhyncha (infraorders Cicadomorpha and Fulgoromorpha) is provided for the Republic of Karelia and the Murmansk Region as well as the adjacent territory of the Arkhangelsk Region in the Vodlozersky National Park. The list contains information on the habitats with detailed geographical references, biogeographical province, biotope, sampling method, date, collectors, and the amount of the material studied for each species. In total for the studied area, 59 species are reported from the infraorder Cicadomorpha: Aphrophoridae - 7 species, Cicadellidae - 51 species, Membracidae -1 species, and 7 species from the infraorder Fulgoromorpha: Cixiidae - 4 species, Achilidae - 1 species, Delphacidae - 2 species.
