Abstract
Centrocoris volxemi (Puton) is a Palearctic coreid native to the Irano-Turanian floristic region and is reported here for the first time in North America and the western US (Utah and Idaho). The species was collected during surveys in Utah in 2021. We also discuss online records and images from 2020–2021 in Utah and Idaho that appear consistent with C. volxemi. The number of records, broad distribution, and field observations suggest that the species is firmly established. Field observations indicate that the primary host in the US is prickly Russian thistle, Salsola tragus L. We provide diagnostic characters and illustrations of the species to facilitate its identification and separation from Centrocoris variegatus Kolenati, another Palearctic species established in the US and first reported from central to central-western California in 2009.
