Taxonomy

Heteroborips Reitter, 1913: 79.

Xyleborinus and Xyleborus

Distribution

Distributed throughout Europe and temperate Asia including the Himalayas. One species is introduced and established in USA (Hoebeke and Rabaglia 2008Hoebeke and Rabaglia 2008:

Gallery system

The gallery system of Heteroborips is unique among xyleborines and lies wholly between the bark and wood (Mandelshtam et al. 2019Mandelshtam et al. 2019:

Remarks

The genus was considered a synonym of Xyleborus for many years. It was recently resurrected and reviewed by Mandelshtam et al. 2019Mandelshtam et al. 2019:
