Debus robustipennis (Schedl) comb. n.

Xyleborus robustipennis Schedl, 1954

Specimens examined.

Indonesia, Borneo (lectotype, NHMW).

Comments.

All diagnostic features of Debus present, including antennal club form, prolonged pronotum, emarginate declivity.

Lectotype of Xyleborus robustipennis Schedl very similar to non-type specimens of Debus amphicranoides (Hagedorn) in USNM, only slightly larger. Schedl (1954) indicated that Xyleborus robustipennis differs from Xyleborus amphicranoides very little, merely by shallower and wider declivital emargination, having the lateral declivital costa between teeth 1 and 2 more elevated, and lateral declivital process shorter. Type of Debus amphicranoides not available, thus synonymy could not be confirmed.
