摘要：
The genus Cottus contains more than 60 species that are common in freshwater bodies of northern Eurasia and North America. Despite the abundance of species, this genus has been insufficiently studied in Eastern European rivers and lakes. The new taxon Coitus cyclophthalmus sp. nov. was found in the Neman/Nemunas and Venta river systems (Baltic Sea Basin). Coitus cyclophthalmus is sister and most morphologically similar to Coitus gobio. The new species has the following diagnostic characters: round, protruding (tubular) eyes near front of head; dermal papillae on top and sides of head, naked body, absence of bony prickles, full trunk canal with 32-36 pores. The description of Cottus cyclophthalmus and a new finding of Coitus microstomus improved understanding of the Eastern European biodiversity.
