Abstract

The article provides an overview of the current state of the genus Ethmolaimus de Man 1880. The species of this genus inhabit fresh and brackish water bodies, sea and in moist soil. Currently, 13 valid species are known, of which 8 species are registered in Russia, and 7 of them are found in Lake Baikal. The study revised the diagnosis of the genus. The morphological diagnosis of the main morphological characters of males of the species of the genus Ethmolaimus, as well as pictorial keys have been compiled.
