On the genus Rhagiosoma and the identity of R. madagascariense (Coleoptera. Chrysomelidae: Sagrinae: Megamerini)
Acta Entomologica Musei Nationalis Pragae 47: 195-202, 2007
Abstract: The genus Rhagiosoma Chapuis, 1878, is removed from the synonymy with Megamerus
Mac Leay, 1827. Mecynodera madagascariensis Heyden, 1877, is transferred to
Rhagiosoma, its taxonomic status is revised and species rank restored.
Rhagiosoma chapuisi nom. nov. is proposed as a replacement name for R.
madagascariense Chapuis, 1878, nec Heyden, 1877. Lectotypes are designated for
both species and their taxonomic status is discussed along with the position of
Prionesthis Lacordaire, 1845. A list of all Rhagiosoma species is presented.
Key words: Coleoptera, Chysomelidae, Sagrinae, Rhagiosoma, Megamerus, Mecynodera, Prionesthis, taxonomy, lectotype designation, revised status, new name, Madagascar, Australia
