The Bark-Gnawing Beetles of Montana, USA (Coleoptera: Trogossitidae, Peltidae, and Lophocateridae), Including New Substantial Distributional Records for Tenebroides collaris (Sturm)

Abstract Eight species of Trogossitidae, three of Peltidae, and one of Lophocateridae are reported from Montana. Of these, six represent new state records. Records of Tenebroides collaris (Sturm) represent a substantial new westward range extension; supported by additional new records from Colorado, this species appears to be established in the western Great Plains.
