New finds of sawflies (Hymenoptera: Xyelidae, Tenthredinidae) in Western Siberia

This study documents 12 sawfly species collected in Western Siberia, including seven new records for the region: Stethomostus funereus (Klug, 1816), Anoplonyx lariciphagus (Zaddach, 1883), Euura imperfecta (Zaddach, 1876), Pristiphora nigella (Förster, 1854), P. pseudogeniculata Lindqvist, 1969, Pseudodineura enslini (Hering, 1923), and Tenthredo scrophulariae Linnaeus, 1758. For five additional species — Xyela julii (Brébisson, 1818), Dolerus nigratus (O.F. Müller, 1776), D. pratorum (Fallén, 1808), D. sanguinicollis (Klug, 1818), and Allantus truncatus (Klug, 1818) — their distributions in Western Siberia have been updated. Most specimens were collected in specific plant communities during spring.
