Revision of genera Gyratogaster, Leianisorhynchus and Altonomus (Coleoptera: Curculionidae: Entiminae: Cyphicerini)

Abstract: The genera Gyratogaster K. Daniel et J. Daniel, 1903 and Leianisorhynchus Pic, 1905 are transferred from the tribe Omiini Shuckard, 1840 to Cyphicerini Lacordaire, 1863 and listed near to the genus Altonomus Desbrochers, 1907 in the subtribe Mylacorrhinina Reitter, 1913. All three genera are redescribed. All species from these genera are redescribed, illustrated and listed in keys and in the check-list. Two new species are described, Gyratogaster podlussanyi sp. n. from Turkey and Altonomus jelineki sp. n. from Israel. Gyratogaster comosa K. Daniel et J. Daniel, 1903 is removed from synonymy with G. larinoides (Reitter, 1896) and reinstated as a valid species. New combinations are proposed: Leianisorhynchus wittmeri (Pesarini, 1971) (from Gyratogaster), Altonomus modestus (Iablokoff-Khnzorian, 1957) and A. vernalis (Iablokoff-Khnzorian, 1957) (from Mylacorrhina Reitter, 1913). Holotypes of Gyratogaster larinoides (Reitter, 1896) and Altonomus villosus (Reitter, 1906) and lectotype of Altonomus reitteri (Stierlin, 1884) are designated. Males of Gyratogaster rufithorax Pesarini, 1975 and G. podlussanyi sp. n. are the first males of the genus Gyratogaster to be described. Genitalia of both sexes are described and illustrated in all three genera for the first time.
