Diuncus adossuarius (Schedl 1951) comb. n.

Previous genus: Xyleborus

Diagnosis: Two small recurved spines on each elytron. Declivity surface shagreened, dull, interstriae often slightly elevated, each with a line of minute granules. Elytral disc surrounding the teeth tends to be flat or concave (impressed). Declivity with minute appressed setae.

Length: 2.3–2.5 mm.

Discussion. Named by Eggers, but name, description, and illustration were published by Schedl (1952 a). Schedl (1952 a) relates the species to X. dossuarius Eggers (Vietnam, Philippines), but mentioned its larger size, longer elytral disc, shorter declivity and the presence of fine pubescence. Wood & Bright (1992) indicate the year of description as 1952, however to our knowledge the description was published in 1951.

Biology: Described and previously known only from Philippines.

Examined material: New Guinea, Owen Stanley Range, Goilala, (BBM); Philippines, Luzon, (holotype, NHMW); Philippines, Luzon, (paratype, NHMW); Philippines, Luzon, (co-type, USNM).
