Bark and Ambrosia Beetles of the World

Bright (1977, 1981) treats quercinus Wood as a synonym here. This synonymy was rejected by Wood (1982). Given that guatemalensis in the sense of Wood (1982) is only known from Guatemala, Bright’s (1981) record of guatemalensis from western Texas should probably be referred to quercinus Wood. The identity of these 2 species needs to be re-examined.
