A review of the genus Hadrodemius Wood, with new synonymy and a key to species (Coleoptera: Curculionidae: Scolytinae)

The eight species included by Wood and Bright (1992) in the Palaeotropical scolytine genus Hadrodemius Wood are reviewed. The following new synonymy is proposed: Hadrodemius comans (Sampson) (= Xyleborus amorphus Eggers syn.n., = Xyleborus metacomans Eggers syn.n.), Hadrodemius globus (Blandford) (= Xyleborus tomentosus Eggers syn.n.), Hadrodemius pseudocomans (Eggers) (= Xyleborus artecomans Schedl syn.n.). Hadrodemius (Xyleborus) pubifer (Schedl) is transferred to the genus Coptodryas Wood. Xyleborus melli Schedl is misplaced by Wood & Bright (1992) as a synonym of Hadrodemius amorphus and is here transferred to Xylosandrus Reitter. The following new synonymy is proposed: Xylosandrus amputatus (Blandford) (= Xyleborus melli Schedl syn.n.). A key to the females of the three species now included in the genus is provided. The taxonomy, distribution and biology of the species are briefly reviewed, and some new records included.
