Abstract:
"A jaw of Ruscinomys (Mammalia, Rodentia) from Pikermian of Samos is described as Ruscinomys hellenicus, new species. It proves the complex origin of the genus Ruscinomys, which is not a phylogenetic unit, but which consists of a number of parallel evolutionary lineages. Each lineage should be distinguished as a separate genus or subgenus. However, none of these lineages is as yet sufficiently known at the present time to permit the erection of new genera or subgenera. The species described so far are grouped in an attempt to outline the composition of the genera or subgenera yet to be described"--P. 8-9.
