- Abstract
Two new species of Potamothrix (Oligochaeta: Tubificinae), P. rhytipeniatus, new species and P. aductus, new species, are described from Fuxian Lake and Xingyun Lake of Yunnan Province, southwest China. Potamothrix rhytipeniatus differs from congeners by its wrinkled penis surface and vasa deferentia entering the atrium subapically. Potamothrix aductus is distinguishable from all congeners by lacking a spermathecal duct. Hitherto, 31 species of freshwater oligochaetes have been recorded from Yunnan Province, including seven endemic species from plateau lakes.
