Treatment

Diuncus duodecimspinatus ( Schedl 1936) comb. n.

Previous genus: Xyleborus

Diagnosis: One of the largest Diuncus , with the most conspicuous elytral armature. The posterolateral costa surrounds the posterolateral broadened margin of elytra as an elevated carina, but on the upper part of declivity it is continued in each interstria as a pointed tooth with flattened base. The teeth are relatively equal in size, except for the tooth in interstria 3, which is greatly enlarged. The declivity is conspicuously broadened laterally, nearly concave. In fresh specimens, the elytra are darker than the pronotum.

Length: 3.0 mm.

Biology: Common associate of Hadrodemius globus throughout New Guinea. Galleries often contain several males of very different sizes.

Examined material: New Guinea, Oro Province, Mt. Lamington, (lectotype, NHMW); PNG: Madang Prov. (213), Oro Prov. (13), J. Hulcr 2002–2006 ( MSUC, 8).
