Abstract

This review of the tribe Xyleborini (Coleoptera: Scolytidae) includes two genera, Xyleborus Eichhoff, with 17 species, and Xylosandrus Reitter, containing 3 species. All species are described and most are illustrated. Keys for the separation of the genera and species are provided. Distributional and biological data are given. New combinations are: Xyleborus obliquus (Leconte) (= Pityophthorus obliquus Leconte); X. lecontei (Hopkins) (= Ambrosiodmus lecontei Hopkins), and X. sayi (Hopkins) (= Anisandrus sayi Hopkins). New synonymies are: Xyleborus obliquus (Leconte) (= Ambrosiodmus linderae Hopkins); X. obesus Leconte (= Anisandrus populi Swaine); X. ferrugineus (Fabricius) (= X. retusicollis Zimmerman and X. soltaui Hopkins); X. xylographus (Say) (= X. inermis Eichhoff and X. planicollis Zimmerman); X. volvulus (Fabricius) (= X. schwarzi Hopkins and X. rileyi Hopkins), and X. howardi Hopkins (= X. fitchi Hopkins). A Japanese species, X. rubricollis Eichhoff, is reported from the United States for the first time. A neotype is designated for X. xylographus (Say).
