Four bathyal species of the subfamily Phallodrilinae (Phallodrilus constrictus n.sp., P. grasslei Erséus, 1984, Bathydrilus connexus n.sp. and B. longiatriatus Erséus, 1983) are reported from the northern part of the Gulf of Mexico. Phallodrilus constrictus is characterized by bifid penial setae (three per bundle), and heavily muscular atria and copulatory sacs, the latter enclosing pendant penes. Barhydrius connexus, which belongs to the ‘B. adriaticus group.’ has more or less single-pointed setae in postclitellar segments, and blunt, somewhat chisel-shaped penial setae (two, occasionally three, per bundle).
