Abstract

Marionina biwaensis sp. nov. is described from Lake Biwa. This new species differs from all other Marionina species: lacking lateral chaetae completely and ventral chaetae in II, segment number 38-43, origin of dorsal blood vessel XV or XVI, spermathecal ampullae with irregular protuberances and chaetal distribution 1 per postclitellar bundles. In addition, the descriptions of M. coatesae, M. nevisensis, and M. riparia are augmented and recorded here for the first time in Japan.
