Comments.

Type specimen of Xyleborus marginicollis Schedl represents one end of a continuum of variation in Diuncus justus : short (1.5 mm) but robust (most representatives of Diuncus justus slightly longer and more slender). Diagnostic characters identical: surface of declivity devoid of vestiture, no elytral denticles, smooth impression across interstriae 2 and 3 (very shallow).
