A taxonomic revision of the Phreodrilidae (Oligochaeta)



Seven of the 20 former species of the Phreodrilidae have been examined. Information derived from a study of this material has necessitated a re-assessment of the interpretations of some of the anatomical features formerly employed in the separation of genera. As a result, all of the known species are merged in the single genus Phreodrilus with seven subgenera, 17 species and two taxa recognizable only as unidentifiable phreodrilids.
