New state records for Nearctic false click beetles (Coleoptera: Eucnemidae)

New state records for 49 species of Eucnemidae (Coleoptera) are reported throughout the United States and a single species is newly reported from Utah. Diagnostic remarks are offered for Xylophilus crassicornis Muona and distributional observations are discussed for Dirrhagofarsus lewisi. The importance of retaining by-catch from statewide, regional, and national surveys for future studies is also discussed. Over the last five years, opportunities were presented on many occasions to identify more than 1500 Eucnemidae from four private collections and eight institutional collections. Most of the specimens recently studied and identifi ed came from the Carnegie Museum of Natural History as by-catch or residue material collected from various fl ight intercept traps deployed during the national bark beetle surveys conducted by the United States Department of Agriculture.
