Heteroptera in forest-tundra and lowland open woodlands in Northeastern Yakutia [Russian]

摘要

Sixty-seven Heteroptera species of 10 families are distributed in the forest-tundra and lowland thin stands of northeastern Yakutia. The highest species diversity is characteristic of Muridae (54%) and Saldidae (12% of the total species) families. Tundra and forest-tundra elements are represented by four arctic species (Leptopterna ferrugata, Orthotylus discolor, O. artemisiae, and Chlamydatus acanthioides) and seven arctoboreomontane ones (Chiloxanthus stellatus, Ch. suturalis, Nabis inscriptus, Closterotomus samojedorum, Teratocoris viridis, T. caricis, and Chlamydatus wilkinsoni). Five species (Nabis nigrovittatus, Acrotelus pilosicornis, Acalypta elegans, Stictopleurus sericeus, and Aelia firida) are steppe elements in the sic-tundra Heteropteran fauna that confirms a wide distribution of cryosteppe communities in the Yana-Indigirka and Kolyma lowlands during the Late Pleistocene.
