Notes
Two new stygobiont species of Rhyacodrilinae (Tubificidae, Oligochaeta), Rhyacodrilus amphigenus, sp. n., and Rhizodriloides phreaticola, g. n., sp. n. are described from the phreatic and hyporheic waters of the alluvial plain of the French upper Rhone. Further information is given about the distribution of the genera Rhyacodrilus and Rhizodriloides in France and ecological features of several species according to their rate of endemicity and a typological classification of the epigeous and subterranean aquatic environment.
