Ambrosiophilus atratus
Hulcr and Cognato, 2010: Listed as occurring in New Guinea by Wood and Bright (1992) but its presence is unlikely. Native to temperate and subtropical East Asia, recently introduced into North America and Europe. Treated here for completeness. Not mycocleptic, each female creates independent gallery. Kirkendall and Faccoli, 2010: This species is native to east Asia and is now well established in North America. It can now also be found in the temperate zone of Europe. This xylomycetophagus species utilizes broadleaf trees as its host and breeds through inbreeding. Rabaglia et al. 2006: This Asian species was first reported in North America in 1990 (Atkinson et al. 1990) from Georgia, Maryland, Tennessee, Virginia, and West Virginia. Its wide distribution at that time indicates that it was likely introduced well before then. It has since been found as far west as Florida. It seems to be related to A. dispar, but it can be distinguished by the smaller serrations on the anterior margin of the pronotum, and the weakly bisulcate elytral declivity with longer interstrial setae.
