A taxonomic revision of the genus Baldorhynchus (Di Marco & Osella, 2002) stat. n. (Coleoptera, Curculionidae, Entiminae).

The Otiorhynchus subgenus Baldorhynchus Di Marco & Osella, 2002 is revised and elevated to the genus level, stat. n.. The following species-level taxa were also elevated to the species level: Baldorhynchus caoduroi (Osella, 1983) stat. n. from Otiorhynchus ( Baldorhynchus) amicalis caoduroi (Osella, 1983); Baldorhynchus comottii (Osella, 1983) stat. n. from Otiorhynchus ( Baldorhynchus) moczarskii comottii (Osella, 1983); Baldorhynchus lessinicus (Osella, 1983) stat. n. from Otiorhynchus ( Baldorhynchus) amicalis cenomanus (Colonnelli & Magnano, 2003) = Troglorhynchus amicalis ssp. lessinicus (Osella, 1983); Baldorhynchus toscolanus (Osella, 1983) stat. n. from Otiorhynchus ( Baldorhynchus) kahleni toscolanus (Osella, 1983) and Baldorhynchus valvestinus (Osella, 1983) stat. n. from Otiorhynchus ( Baldorhynchus) kahleni valvestinus (Osella, 1983). The following new combinations and resurrections are also proposed: Baldorhynchus carinatus (Osella, 1983) nom. res. from Troglorhynchus carinatus Osella (1983) = Otiorhynchus (Troglorhynchus) serradae Colonnelli & Magnano (2003); Otiorhynchus (Troglorhynchus) radjai (Di Marco & Osella, 2002) comb. n. from Otiorhynchus ( Baldorhynchus) radjai Di Marco & Osella (2002); Baldorhynchus ferrarii (F.Solari, 1955) nom. res. from Troglorhynchus ferrarii F. Solari (1955) = Otiorhynchus ( Baldorhynchus) adrianoi Magnano (2001); Baldorhynchus judicariensis (Osella, 1983) nom. res. from Troglorhynchus judicariensis Osella (1983) = Otiorhynchus ( Baldorhynchus) clibbianus Colonnelli & Magnano (2003); Baldorhynchus lessinicus (Osella, 1983) nom. res. from Troglorhynchus amicalis ssp. lessinicus Osella (1983) = Otiorhynchus ( Baldorhynchus) amicalis cenomanus (Colonnelli & Magnano, 2003). Twenty-one species are new to science: Baldorhynchus agostianus Bello & Osella sp. n., Baldorhynchus anachoreta Bello & Osella sp. n., Baldorhynchus bodeianus Bello & Osella sp. n., Baldorhynchus branchianus Bello & Osella sp. n., Baldorhynchus cohabitator Bello & Osella sp. n., Baldorhynchus danzii Bello & Osella sp. n., Baldorhynchus deceptor Bello & Osella sp. n., Baldorhynchus grottoloi Bello & Osella sp. n., Baldorhynchus magasaensis Bello & Osella sp. n., Baldorhynchus marianus Bello & Osella sp. n., Baldorhynchus metallarius Bello & Osella sp. n., Baldorhynchus monguzzii Bello & Osella sp. n., Baldorhynchus nardii Bello & Osella sp. n., Baldorhynchus paladinii Bello & Osella sp. n., Baldorhynchus pedersolii Bello & Osella sp. n., Baldorhynchus pivai Bello & Osella sp. n., Baldorhynchus regalini Bello & Osella sp. n., Baldorhynchus ruzzieri Bello & Osella sp. n., Baldorhynchus saccoi Bello & Osella sp. n., Baldorhynchus settei Bello & Osella sp. n. and Baldorhynchus tedeschii Bello & Osella sp. n.. Thirty-seven species are assigned to the genus Baldorhynchus . Finally, in addition to having redescribed Baldorhynchus moczarskii (Breit, 1913), we designate a neotype for Baldorhynchus baldensis (Czwalina, 1875). A key to species and groups of species, a checklist of all species, diagnosis, distribution maps and details of ecology are provided.
