Anisandrus maiche Stark, an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Pennsylvania, Ohio, and West Virginia. This is the twentieth species of exotic Xyleborina documented in North America. This species, along with three others occurring in North America, were formerly placed in Xyleborus Eichhoff, but currently are assigned to Anisandrus Ferrari. Descriptions of generic characters used to separate Anisandrus from Xyleborus, a re-description of the female A. maiche, and an illustrated key to the four North American species of Anisandrus are presented.
