Abstract
An annotated checklist of the 102 species of Buprestidae (Coleoptera) known to be present in the state of Idaho is provided, with photographs and detailed distribution maps for each species. The checklist is based on label data from 7,506 museum specimens, 21 observations obtained from iNaturalist.org and BugGuide.net, and 63 distribution records from published literature. Buprestis consularis Gory is a new record for Idaho, formerly reported as Buprestis nutalli Kirby, which is not known to occur in the state. Obscure past records of Anthaxia retifera LeConte and Melanophila occidentalis Obenberger published in the literature are regarded as dubious and are not confirmed by actual specimens. These species are therefore excluded from the checklist. Knowltonia calida (Knull) and Chrysobothris caurina Horn are also absent from Idaho, their previously published records based on misidentifications of K. biramosa Fisher and C. leechi Barr, respectively.
