A subspecies of jewel beetle in the family Buprestidae. Adults have been observed on dead and dying conifers, particularly Pinus ponderosa and Abies concolor. Females search trunks for oviposition sites, probing cracks and crevices with their ovipositor. The subspecies is distributed in western North America, with records from Alberta and British Columbia in Canada and the western United States.
