Macroseta Erseus, 1975 is considered a junior synonym to Bathydrilus Cook, 1970 after examination of the type material of B. asymmetricus Cook, 1970. Bathydrilus is defined mainly by its organization of the male duct: vas deferens entering ectal half of atrium, one prostate gland attached to ectal part of atrium, near entrance of vas deferens, another prostate attached to apical, ental end of atrium. B. atlanticus sp.n., B . hadalis sp.n., B. meridianus sp.n., B. graciliatriatus sp.n. and B. longus sp.n. are described from specimens collected from various parts of the world; most of the species are deep-sea forms. Phallodrilus rohdei Ja- mieson, 1977 and Phallodrilus adriaticus Hrabĕ, 1971 are transferred to Bathydrilus, and a Caribbean/Bermudian form is described as B. adriaticus trisetosus subsp.n. The taxonomy and morphology of the different species, including B. rarisetis (Erstus, 1975) comb.n., are discussed. Bathydrilus is included in the sub-family Phallodrilinae. It appears closely related to Phallodrilus Pierantoni, 1902, from which it is distinguished principally by differences in the relative positions of the vasa deferentia, the atria and the prostate glands.
