Trichocnemis
Trichocnemis is a genus of longhorn beetles (Cerambycidae) in the subfamily Prioninae. The genus contains two species distributed in western North America: Trichocnemis pauper and Trichocnemis spiculatus (the ponderosus borer). Historically, species of Trichocnemis have often been treated as members of the genus Ergates, but modern taxonomic treatments separate them based on morphological differences including head size, mandible shape, and antennae length. The larvae of T. spiculatus are notable wood-borers in ponderosa pine and inspired improvements to chainsaw design.
