Аннотация: Eight species of Heteroptera, including one adventive species (Elasmostethus sp.) and one aquatic species (Callicorixa producta), were found on Dolgii Island (the southern tundra subzone). Among the seven indigenous species, six are Holarctic; the distribution of five species is confined to tundra landscapes, and five species are predators. The phytophagous Chlamydatus acanthioides and Nysius groenlandicus are associated with the most humid and the best drained parts of the inland landscape, respectively. The predatory species of the family Saldidae, Chiloxanthus arcticus, Ch. stellatus, Salda littoralis, and Calacanthia trybomi, show specific patterns of distribution among the biotopes with different levels of humidity and salinity. The biotopic preferences of Chiloxanthus species vary significantly within their ranges. The northward expansion of Heteroptera appears to be limited by the mean July isotherm of +3°C.
