Фауна пядениц (Lepidoptera, Geometridae) восточного Сихотэ-Алиня в районе Ботчинского заповедника II. Подсемейства Larentiinae, Sterrhinae и зоогеографический анализ

Abstract

The article studies the little-known fauna of Geometridae (Lepidoptera) of the middle sector of the eastern Sikhote-Alin, the Russian Far East, the central part of which is the Botchinsky Nature Reserve. The second part contains materials on 161 species of Geometridae from the subfamilies Larentiinae and Sterrhinae, of which Epirrhoe pupillata (Thunberg, 1788), Malacodea regelaria Tengström, 1869 and Eupithecia analoga Djakonov, 1926 are noted for the Khabarovsky Region for the first time, as well as the analysis of the entire explored fauna of the geometrid moth in the region. Including the materials published in the first part of the work, we identified 247 species of geometrids in the study area, of which 223 species were recorded on the territory of the Botchinsky Nature Reserve and its buffer zone and 140 species were noted for the first time for the entire study area. The distribution of 101 species in the Far East was significantly expanded. In particular, the study revealed that the ranges of a number of boreal species shifted abnormally to the south along the eastern Sikhote-Alin, which could be due to the cold Sea of Okhotsk. In terms of areal composition, the geometrid fauna of this territory can be characterized as transitional between the Boreal and East Asian regions of the Holarctic kingdom.
