Surveys identify two new eumenine wasp species in Uzbekistan, expanding their known geographical range.
During faunistic surveys of the family Vespidae conducted in Uzbekistan between 2022 and 2025, two eumenine wasp species – Euodynerus (Euodynerus) caspicus (Moravitz, 1873) and Symmorphus (Symmorphus) crassicornis (Panzer, 1798) – were recorded for the first time from Uzbekistan. These findings significantly expand the known distribution range of both species in Central Asia and contribute to the knowledge of the Eumeninae fauna of the region. Diagnostic characteristics and notes on habitat preferences are provided.
