Antonius A 1968 (citation)- defines new genus and moves some Convoluta into it. Definition p 309: "Bursa with a cuticular nozzle. Genital openings separate, always ventral. Copulatory organ consists of a tube shaped, mostly ciliated penis formed from a high epidermis (antrum masculinum), always in combination with a adenodactylus. A seminal vesicle as a split space, consisting of a secretory and a sperm guide part, is attached to the proximal end of penis. Vagina mostly ciliated. Genital openings without stimulatory organs. Brain insunken. Anterior glands with or without a common duct, sometimes very extensive. Mostly without enrolled sides. Decked with symbiotic algae, rhabdites, pigments and conspicuous concretions. No pigment eyes." List species: Adenopea illardatus Adenopea chuni Adenopea cenata from key p 310- characters, has bursa with one anterior nozzle, separate genital openings, without a seminal vesicle, with adenodactyls. All are pelagic, adenodactyls in each of 3 species, sperm and secretory parts of vesicle, end of penis like a vesicle- without a good wall- a sort of split in parenchyma? Etc, on development from a Proaphanostoma form- see diagram figure 8, ciliated female antrum. Faubel A 1976 (citation)- p 23 definition and list of species. Made changes to Antonius A 1968 (citation). Changed this: "mostly ciliated penis formed from a high epidermis (antrum masculinum), always in combination with a adenodactylus." to this: "copulatory organ present." Says one of adenodactyls is seminal vesicle. Geographic distribution: Brazil, Suez Canal, Gulf of Naples.
