Notes.

A widely introduced species around the globe, X. crassiusculus  has spread in the US along the lower Piedmont region and coastal plain to North Carolina, Louisiana, Florida, and beyond ( Atkinson et al. 2012). The first US record is based on a specimen collected in South Carolina in 1974 ( Anderson 1974, as Xyleborus semiopacus  ). Distinguished by the confused declivital granules giving the declivity a dull appearance. Causes economic damage in nurseries and stored hardwood lumber ( Smith and Hulcr 2015).
