On two Italian Lithobius species described by Silvestri, with taxonomic notes on the genus Eupolybothrus Verhoeff (Chilopoda, Lithobiida)

A re-examination of the types of Lithobius occultus Silvestri, 1894, and Lithobius excellens Silvestri, 1894, from Italy, has shown that the two are based on specimens of the same species which takes the name of Eupolybothrus (Schizopolybothrus) excellens (Silvestri, 1894), and is probably most closely related to E. tabularum (Verhoeff, 1937). A tentative survey of the subgenera of the genus Eupolybothrus Verhoeff, 1907, is given, and a new subgenus, Leptopolybothrus nov. subgen., type-species Lithobius leptopus Latzel, 1880, is erected.
