Xyleborus is by far the largest
bark beetleA bark beetle is one of approximately 220 genera with 6,000 species of beetles in the subfamily Scolytinae. Traditionally this was considered a distinct family Scolytidae, but nowadays it is understood that bark beetles are in fact very specialized members of the "true weevil" family...
genusIn biology, a genus is a taxonomic unit used in the classification of living and fossil organisms. The term comes from Latin genus "descent, family, type, gender" , cognate with – genos, "race, stock, kin" ..In addition, genus is a taxonomic rank in the hierarchy In biology, a genus (plural:...

XyleboriniXyleborini are a tribe of bark beetles, 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....
.
Xyloborus nowadays includes a high number of formerly independent genera. In addition, the genera
Coptoborus,
Cryptoxyleborus and
Euwallacea are often included here too; this may be correct as they seems to be very close relatives. Less often,
Ambrosiodmus,
Premnobius and
Xyleborinus are included in
Xyleborus but they seem to be well distinct;
Premnobius might even not belong to the Xyleborini at all.
The different species can be best told apart from the gallery burrows they build and from what trees they infest.

The different species can be best told apart from the gallery burrows they build and from what trees they infest. A rather notorious member is
X. dispar which causes pear blight.
