A Taxonomic Revision of the Weevil Genus Hypoglyptus Gerstaecker, 1855 (Coleoptera Curculionidae)

The genus Hypoglyptus Gerstaecker, 1855 is herein revised for the first time. Based on adult morphological characters, five species are recognized as valid: Hypoglyptus conspersus (Leonhard, 1912) (Greece), H. elegans (Brullé, 1832) (Greece, Albania), H. gracilis Kiesenwetter, 1864 (Greece), H. graecus (Pic, 1902) (Greece), H. heydeni Faust, 1889 (Greece, Syria, Turkey). For this last species a lectotype is designated. Hypoglyptus pictus Gerstaecker, 1855 is proposed as n. syn. of H. elegans (Brullé, 1832). Male and female genitalia have been examined and are illustrated for the first time. The five species are very similar to and separable from each other by a few subtle differences in the shape, the sculpture, and the vestiture of the pronotum and elytra and in the more or less toothed femora. On the basis of morphological characters, the genus Hypoglyptus, previously incertae sedis in Curculionidae, is here tentatively placed in the tribe Smicronychini of the subfamily Curculioninae.
