Annotation:
477 species of Lepidoptera, Noctuoidea (Erebidae, Nolidae, Noctuidae) have been reliably recorded in Cisbaikalia and Western Transbaikalia (Buryatia). The maximum species richness is noted in forest-steppe (285 species) and lower taiga (248 species) belts, the largest proportion of highly specialized species is characteristic of goltsy (20.5 %) and steppe (16.9 %) belts. In terms of latitudinal distribution, the core of the fauna (65.2 %) is formed by subboreal species. Regarding the longitudinal structure of the ranges, transpalearctic species predominate. The fauna is of a mixed nature with pronounced western (Euro- Siberian, Central Palearctic) and eastern (East Palearctic, Central-East Palearctic, South Siberian-Palaeoarchearctic) elements. Four main ecological complexes have been identified: meadow-steppe, forest, wetland coastal, and high-mountain. The proportion of local (64 %) and rare (44 %) species is exceptionally high, indicating a high degree of specialization and vulnerability of the fauna.
