Revision of the new world Hylurgops LeConte (Coleoptera: Curculionidae: Scolytinae)

Abstract

The New World species of the genus Hylurgops LeConte are revised. Hylurgops subcostulatus Mannerheim is transferred to Pachysquamus, new genus. A revised key to the Hylastina is presented to include the new genus Pachysquamus. The Nearctic H. knausi Swaine is a valid taxon distinguishable from H. planirostris Chapuis of the high montane Neotropical region. The subspecies H. r. rugipennis Mannerheim and H. r. pinifex Fitch are considered full valid species. A key to the Hylurgops species of the New World is presented.
