Abstract

The walnut twig beetle, Pityophthorus juglandis Blackman (Coleoptera: Scolytidae, sensu Wood 2007), was first described from specimens collected in 1896 in Grant Co., New Mexico (Blackman 1928). Bright (1981) and Wood & Bright (1992) reported a distribution for P. juglandis that included Arizona, California, and New Mexico in the U.S. and Chihuahua in Mexico. Cranshaw (2011) described the recent expansion of the range of P. juglandis to include the western U.S. states of Colorado, Idaho, Oregon, Utah, and Washington, as well as the eastern U.S. state of Tennessee.
