This is the only species of the genus. Bright and Rabaglia (1999) placed it in the Dryocoetini  based on tibial characters, but molecular analyses place it within the Xyleborini  ( Jordal et al. 2000, Jordal 2002). Distinguished by the obliquely truncate antennal club, the narrow protibiae with a few large teeth on outer margin, and by the distinctly concave, densely pubescent, and unarmed elytral declivity.
