Taxonomy: Type specimens of Xyleborus machili could not be located in the NIAES collection. However, the description of the species, and specimens identified as X. machili by Miloš Knížek agree in all relevant characters with the holotype of X. depressus (NHMW). The holotype of Xyleborus kojimai (NMNH) was examined and found to be conspecific with the holotype of X. depressus . X. machili has priority over the other two species. It has the generic characters of Ancipitis Hulcr and Cognato, 2013, and is here transferred to that genus.
