Xyleborus

With over 500 species, Xyleborus is by far the largest bark beetle genus in the tribe Xyleborini.

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. A rather notorious member is X. dispar which causes pear blight.
