MACROHETEROCERA БЕЗ GEOMETRIDAE И NOCTUIDAE s. lat. (INSECTA, LEPIDOPTERA) НИЖНЕГО ПРИАМУРЬЯ

Abstract

A distribution of 182 species of the so-called bombycoid moths from superfamilies Uranioidea, Drepanoidea, Lasiocampoidea, Sphingoidea, Bombycoidea, Notodontoidea, Noctuoidea (excluding Noctuidae s. lat.), as well as Hepialidae, Cossidae, Limacodidae, Zygaenidae, Thyrididae, within the Lower Amur territory is discussed. Effectiveness of the distributional barriers between main collecting places in Lower Amur and South Primorye is discussed. For the entire species set, the most important barrier is located between Kiselevka-Tsimmermanovka (51˚ 20-25' N, 139˚ E) and the Amur river mouth. It coincides with the north-eastern limits of the polydominant broad-leaved forests. A weaker barrier is located between Khabarovsk and Komsomolsk areas. Several species, like Caligula japonica, don’t overpass a barrier along the river Gur. For obligatory spring species, the most effective barrier is detected between Khabarovsk and Komsomolsk areas; for obligatory autumn species – between South Primorye and Khabarovsk, and between Khabarovsk and Komsomolsk. These barriers act mainly as north-eastern limits of nemoral species; for boreal species these barriers are ten times less effective. The area of the Amur river mouth is inhabited by the subnemoral fauna sensu Dubatolov & Kosterin, 2000, it is transitional between East Asian (Palearchaearctic) and Euro-Siberian Subregions of the Palearctic. Another example of such a transitional territory is the Upper Amur basin, with Eastern Transbaikalia [Dubatolov, Vasilenko & Streltzov, 2003].
