It is now recognized that Oligochaeta and Hirudinea form a clade and should be referred to either as Oligochaeta or Clitellata) Annelid resources, via WWW, Aug. 12, 2005: Phylogeny of the Annelida and allies (In recent times the general view is that Annelida contains polychaetes and the clitellate oligochaetes and leeches, usually as three classes, or latterly with the clitellates as one class or sub-phylum) |
