Three new genera of oriental Xyleborina (Coleoptera: Curculionidae: Scolytinae) Author Hulcr, Jiri Author Cognato, Anthony I. text Zootaxa 2009 2204 19 36 journal article 10.5281/zenodo.189700 f48b8ba7-9ec3-455c-8087-9082458a6f72 1175-5326 189700 AA07F2AD-8D1C-408E-9F44-A7696CF3B1AE Diuncus mucronatus ( Eggers 1923 ) comb. n. Previous genus: Xyleborus Discussion. The holotype of X. mucronatus is probably lost ( Wood & Bright, 1992 ). Specimens available to us were not suitable for neotype designation as they were neither from the same region, nor identified by Eggers. However, two non-type specimens (SMTD, identified by Schedl, and JH coll., identified by R. A. Beaver) were nearly identical to each other. Further, they were nearly identical to the holotype and several non-type specimens of Diuncus conidens (Eggers) . It is likely that these two species are synonymous. Examined material: Philippines , Luzon, Mt. Irid, ( SMTD ), PNG , Madang, J.H. coll. 2004.
