Euwallacea vallidus - Euwallacea validus - Female
Wake County, North Carolina, USA
July 7, 2009
Size: 3.7 mm
These have previously been in Xyle*borus (eg. Wood, 1982 and D&A) but are now considered separate. The posterior side of the antennal club has a clear suture showing a second segment unlike Xyleborus. The protibiae have 12 teeth. Females like this one are much larger and have the prothorax convex.

yes
Probably must be valida, but American beetles had E. validus and my other references still called it Xyleborus validus.
