Characterized by the presence of a cocoon-forming clitellum during part of their life cycles, hermaphroditism, and the absence of parapodia, the clitellates traditionally comprised the Oligochaeta, possessing a few chaetae, and leeches (Hirudinea), which completely lack chaeta ( Brusca and Brusca 2003). According to their simplified appearance they were regarded as a separate class from other annelids and their monophyly was convincingly supported ( Grube 1850; Dales 1963; Fauchald 1977; Rouse and Fauchald 1997).
