Treatment

Beaverium insulindicus ( Eggers 1923) comb. n.

Previous genus: Xyleborus

Diagnosis: Pronotal margin rounded, with elevated recurved carina. The boundary between elytral disc and declivity unclear, continuously rounded. Declivital posterolateral margins broad and flattened, but not beyond the apparent width of elytra, elytra only slightly (or not at all) constricted before the broadened declivity. Declivital punctures small, numerous, confused. Apex of declivity varied, from rounded to small emargination.

Length: 5.3–6.2 mm.

Discussion. The synonymy of the junior name Xyleborus glaberrimus Schedl is confirmed (the holotype of X. glaberrimus examined in NHMW). According to Schedl (1942), X. glaberrimus differs from X. insulindicus by the steeper slope and denser punctures of declivity, which are some of the most plastic characters in this genus.

Previously synonymized species: Xyleborus glaberrimus Schedl.

Biology: Short branching gallery.

Examined material: New Guinea, Morobe Province, Bulolo, (B. H. Jordal), identified as X. annexus by R. A. Beaver ex desc. New Guinea, Fiume Purari, ( MCG); New Guinea, Paumomufluss, (lectotype, USNM); PNG: Madang Prov. (9), Oro Prov. (38), J. Hulcr 2002–2006.
