Treatment

Diuncus dossuarius ( Eggers 1923) comb. n.

Previous genus: Xyleborus

D. dossuarius can be recognized from other Diuncus primarily by a shallow smooth transversal depression on the elytral disc. The interstriae 2 and 3 each bear a minute pointed recurved spine at the summit of declivity. The declivity and the depression in elytral disc are conspicuously dull and pubescent.

Discussion. The species displays all the essential characters of Diuncus : antennae of type 1, very flat; the pronotum rounded, short, with two prominent teeth on the anterior edge; very slender protibiae; no signs of mesonotal or elytral mycangium. The declivity is broadened posteriad and surrounded with elevated carina.

Biology: Collected in the same rattan stem as Anisandrus ater , but it is not clear whether the two species were involved in any association (R. A. Beaver, pers. comm.)

Examined material: Brunei, Temburong, (RAB, 5 indiv.); Philippines, Luzon, (paratype, NHMW); Philippines, Luzon, (holotype, SMTD, 21 indiv.); Philippines, ( USNM, 2 indiv.).
