ABSTRACT. Orthetrum albistylum (Selys, 1848) was first recorded in West Siberia in 2020 in the extreme south of Altaiskii Krai. Further studies in 2021–22 and iNaturalist data from 2025 showed that this species is widespread across Altaiskii Krai. Eleven locations were identified, with the northernmost lying at 53°N. The species is confined to flowing water bodies such as canals and small rivers, as well as semi-flowing water bodies such as ponds on small rivers. It is hypothesised that, over the past two decades, the range of O. albistylum in southern part of West Siberia has expanded northwards by three degrees of latitude.
KEY WORDS: Orthetrum albistylum, distribution, habitat, expansion to the north, West Siberia.
