Peosidrilus biprostatus Baker & Erséus, 1979, is recorded from the Gulf of Mexico, P. coeloprostatus (Cook, 1969) from Maine, and both P. biprostatus and P. acochlearis (Erséus & Loden, 1981) are reported from bathyal depths (off North Carolina) for the first time. Peosidriloides, new genus, does not have lateral spermathecal pores, the feature regarded as an autapomorphy ofPeosidrilus Baker & Erséus, 1979. Peosidriloides hornensis, new species, from the northern Gulf of Mexico, shares some apomorphic features (a short clitellum, long vasa deferentia) with Peosidriloides flabellifer (Erséus, 1984), new combination, but is distinguished from that species by its more numerous anterior setae, its more ventral spermathecal pores, its wider vasa deferentia, and its possession of penial organs.
