| Abstract: | Macquaridriloides gen.n. is established for M. heronae from Heron Reef in Queensland, Australia. The species is characterized principally by its lack of spermathecae, and its elaborate male efferent ducts, each of which consists of (1) a ciliated vas deferens, (2) a ciliated and muscular atrium with diffuse prostates, and (3) a stout muscular, non-ciliar ejaculatory duct opening into a large copulatory sac surrounded by posterior prostates. The genus appears closely related to Macquaridrilus Jamieson, 1968, the habitat and zoogeography of which are briefly discussed. Heronidrilus gen.n. is established for H. fastigatus sp.n. and H. bihamis sp.n. both from Heron Reef. This genus is closely related to Macquaridriloides , but the two species differ from M. heronae in that they possess spermathecae and lack ejaculatory ducts. |
