• Crossidius coralinus jocosus

  Crossidius coralinus jocosus is a subspecies of longhorned beetle in the tribe Trachyderini, endemic to North America. It is characterized by its notably small size compared to other C. coralinus subspecies and reduced black elytral markings. Adults emerge in late summer and early fall to feed on yellow flowers of gray rabbitbrush (Ericameria nauseosa). The subspecies occurs in southeastern Colorado, where it appears to be isolated from nominotypical populations by the San Juan Mountains.
