Abstract.
The genus Rhagiosoma Chapuis, 1878, is removed from the synonymy
with Megamerus MacLeay, 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 substitute 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.
