Notes
Four species of the enchytraeid oligochaete genus Marionina from intertidal habitats are added to the British Columbia species list: Marionina klaskisharum sp. nov., M. nevisensis (Righi and Kanner, 1979), M. southerni Cernosvitov, 1937, and M. glandulifera (Jansson, 1960). Marionina nevisensis is asetate; M. klaskisharum has setal bundles ventrally in II to V, each represented by a single seta; M. glandulifera has only ventral, bisetate setal bundles; and M. southerni has lateral and ventral bisetate bundles in all segments except laterally in II. Marionina nevisensis is elevated from a subspecies of M. achaeta Lasserre, 1964 because of structural differences of their spermathecae and seminal vesicles. The ranges of M. charlottensis Coates, 1980 and M. nevisensis Coates, 1980 are extended, respectively, south to northern California and to include the entire British Columbia coastline.
