Xyleborini are a tribe of ambrosia beetles (alternatively called subtribe Xyleborina of tribe Scolytini), highly specialized weevils of the subfamily Scolytinae. Much of the ambrosia beetle fauna in Eurasia and the Americas consists of Xyleborini species. Some Xyleborini are notorious invasive species.
