INTRODUCTION
Marine Oligochaeta, hardly mentioned in Stephenson’s (1930) classical monograph, have received increasing attention during the past 50 years. The number of known species has increased rapidly, especially with the growing evidence of the diverse oligochaete fauna in sublittoral biotopes (Erséus, 1980a); this leaves taxonomic considerations in continuous state of flux. Biologically and ecologically, marine oligochaetes have received growing attention, at least in some special aspects (e.g. meiofauna, Lassèrre, 1976; zoogeography, Dzwillo, 1966; Erséus & Lassèrre, 1976; Erséus, 1980a).
