This species is known from northeastern Arizona, Utah, northern New Mexico, Colorado, and Wyoming. It is characterized by a shiny, slightly more cordate pronotum than other members of the group, without notable basal punctuation, relatively flat elytral intervals, with small punctures in the elytral striae, and distinctive male genitalia. As first revisers, we choose B. sarpedon Casey as the valid name of this species.
