Diuncus corpulentus ( Eggers 1930) comb. n.

Previous genus: Xyleborus

Discussion. Holotype deposited in FRI, unavailable. Non-types in collections BMNH and RAB examined. 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 mycangium. D. corpulentus does not have denticles on declivity, except for small granules. The declivity is broadened posteriad and surrounded with elevated carina. Interstriae 1 are slightly inflated at elytral apex. Individuals from Thailand have a striking yellow and brown color pattern on pronotum and dark brown elytra.

Biology: JH collected the species in a small branch heavily colonized by Hadrodemius globus (Blandford) . The galleries of the two species were densely intertwined, suggesting parasitic exploitation by D. corpulentus .

Examined material: Thailand, Pong Yaeng N. P., (J. Hulcr 2005, 4 indiv.); Thailand, Nam Nao N.P., (S. Dole, 2 indiv.); locality not recorded, ( BMNH).
