Treatment

Diuncus gorggae Schedl (1973) comb. n.

Previous genus: Xyleborus

Diagnosis: Very similar to Diuncus duodecimspinatus , except for a few differences in the elytral armature. In D. gorggae , the interstriae 4–6 do not bear teeth, only interstriae 2 and 3, of which the tooth in interstria 2 is minute, the tooth in interstria 3 is large. The declivity is conspicuously broadened laterally, nearly concave. Its surface is unusual in that it is dull, softly shagreen.

Length: 2.4–2.6 mm.

Discussion. Schedl (1973) compared the species to Diuncus (as Xyleborus ) duodecimspinatus , and notes the missing teeth on the interstriae 4, 5, and 6. The islands of New Ireland and New Britain are the only localities of occurrence known to us.

Examined material: New Guinea, New Ireland, (holotype, ANIC); New Guinea, New Britain, Gazelle Peninsula, (BBM); New Guinea, West New Britain, Wilelo, (paratype, NHMW).
