LEAF BEETLES (COLEOPTERA, CHRYSOMELIDAE) OF THE “ZVANETSˮ LANDSCAPE RESERVE

Abstract

This paper presents the results of a long-term study of beetles of the family Chrysomelidae in the Zvanets National Landscape Reserve in the Drogichin and Kobrin districts in Brest region. Specimens were collected from 2010 to 2017, primarily in marsh and near-water habitats, with the use of sweep nets, light traps, and Barber and Malaise traps.
The ecological and faunistic list of this family, which includes 139 species belonging to 42 genera and 9 subfamilies has been compiled; 74 species of leaf beetle are recorded for the reserve's entomofauna for the first time. The most species-rich subfamilies are Galerucinae, Chrysomelinae, and Cryptocephalinae, which is generally typical of the European fauna of this family. Some flea beetle species rare in the region as a whole have been found within the reserve: Aphthona franzi Heikentinger, 1944, Chaetocnema compressa Letzner, 1847, Longitarsus aeruginosus (Foudrsa, 1860), L. longiseta Weise, 1889, L. pinguis Weise, 1888, L. rubiginosus (Foudras, 1860), L. symphyti Heikertinger, 1912. For the species Phyllotreta dilatata Thomson, 1866 and L. aeruginosus the west of Belarus is the eastern border of their range.

The subfamily Donaciinae is poorly represented in the fauna of the reserve, species of the subfamilies Orsodacninae and Zeugophorinae with European-Siberian ranges have not been found in its composition. Most leaf beetle species within the reserve have broad areals, but there have been found the species of the steppe entomofauna — Cassida atrata Fabricius, 1787 (Cassidinae) and Hispa atra Linnaeus, 1767 (Hispinae), whose distribution is currently limited to southern Belarus. The ecological structure of the fauna of leaf beetles in the reserve demonstrates the predominance of mesohygrophilous and hygrophilous species.
