Genus Xylodiplosis Kieffer, 1895

The genus includes five species in the Holarctic and Oriental regions. At least three of the species develop in the xylem vessels of freshly cut or damaged hardwood trees. Material collected in southern Norway seems to belong to at least two, possibly three species, distinguishable by morphology, flight time, and/or DNA barcodes. Only one species is reported at this point, as the remaining material requires further study.
