Abstract
Based on long-term studies (1995-2022), the species composition was established and the fauna of seed beetles (Bruchinae) of the Vyatka-Kama region (including the Kungur island forest-steppe) was analyzed. The studied fauna includes 11 species. For Udmurtia, 10 species are given (of which 3 are for the first time), for the Kirov region - 9 species (3 for the first time), for the northeast of Tatarstan - 6 species (1 for the first time), for the Perm Krai - 5 species (3 for the first time). The fauna is heterogeneous in zoogeographical terms. 2 species ( Bruchus atomarius and B. loti ) have trans-Eurasian ranges, and 3 more ( Bruchus affinis , B. occidentalis and Spermophagus sericeus ) have West-Central Palearctic ranges. Bruchidius marginalis and B. villosus are Western Palearctic species, not known east of Vyatka-Kama region. Kytorhinus pectinicornis , found in the Kungur island forest-steppe, has a Holarctic arcto-alpine habitat of a relict type. 8 species of seed beetles are representatives of the local fauna, developing on wild legumes (Fabaceae), and one species ( Spermophagus sericeus ) on bindweeds (Convolvulaceae). 3 species ( Bruchus pisorum , Acanthoscelides obtectus and Callosobruchus maculatus ) - invaders with different centers of origin, came to the region during an unintentional importation with seed products.
