Abstract

There are over 70 species of Pachybrachis Chevrolat known from Arizona. A group of species with tibial spurs on the forelegs of the males consists of three Nearctic species: Pachybrachis coronado Barney, new species, Pachybrachis texanus Bowditch, and Pachybrachis uncinatus Fall. A key to the Tibial Spur Species is given, and a description and figures are provided for each species. New state records are reported for P. texanus and P. uncinatus.
