Cah. Biol. Mar. 44: 275-298.
Abstract / Notes
Two new families, three new genera, four new species, and one previously described species of acoel flatworm collected from shallow marine sediments in Queensland, Australia are described: Wulguru cuspidata (Convolutidae), Stomatricha gen. nov. hochbergi sp. nov. (Otocelididae), and Daku gen. nov. woorimensis sp. nov. (Dakuidae fam. nov.) from Bribie Island, Haplogonaria stradbrokensis sp. nov. (Haploposthiidae) from North Stradbroke Island, and Polycanthus gen. nov. torosus sp. nov. (Polycanthiidae fam. nov.) from Green Island. The family Dakuidae fam. nov. is characterized by having a cone-shaped glandular penis surrounded by a thick seminal vesicle composed of muscles in well-defined longitudinal and circular orientations. The family Polycanthiidae fam. nov. is defined by the possession of a cylindrical copulatory organ composed of five concentric layers of longitudinal and circular muscles that surround an epithelium-lined lumen opening terminally at the posterior end of the animal.
