Notes
A phylogenetic analysis of the species of Pontoscolex has been made using PAUP with a data matrix of 15 characters. The results support Righi (Zoologische Mededelingen Leiden 43, 314-315, 1984) and Borges and Moreno (Bolletino del Museo Regionale di Scienze Naturali Torino, 1992) in their division of the genus into three subgenera, but challenge the diagnostic criteria used by Righi and the evolutionary implications of Borges and Moreno. The subgenera are redefined.
