A new tubificid oligochaete, Krenedrilus towadensis, is described from deep bottoms of the oligotrophic caldera Lake Towada in northern Japan. It resembles K. realis Martínez-Ansemil and Collado, 1996, in the combination of somatic setae, but it is different from all other congeners by the lack of spermathecal setae and epidermal papillae in X, in the structures of penial and supernumerary setae, and in the location of spermathecal pores. The definition of Krenedrilus is revised.
