Abstract

Data on the taxonomic composition of water bugs (Heteroptera: Nepomorpha, Gerromorpha) in the northeast of European Russia are given. A total of 34 water-bug species, which belong to 16 genera and 8 families, are recorded. The species diversity of Nepomorpha and Gerromorpha changes northwards: 33 occur in the taiga zone and only 8 species occur in the tundra zone. The bulk of the fauna consists of Eurosiberian (29%) and trans-Eurasian (26%) species; in latitude-related terms, the temperate group is most richly represented (64%). The species composition of the aquatic and semiaquatic heteropteran fauna of the region is especially similar to that of the tundra and taiga zones of Western Siberia.
