From editor or global species database
Checked: verified by a taxonomic editorEditor's comment Morch (1863: 413, 418) tried to bring some order in what he perceived to be the genus Placostegus, distinguishing two sections: sectio alpha, characterized by a crystalline tube and "horny" operculum; sectio beta, characterized by a "cretaceous" tube and calcareous operculum. He, however, was not consistent in the application of these characters, so his division makes no sense in the present state of knowledge. Only one species, tridentatus, mentioned by Morch remains in the genus Placostegus, with what generally is regarded to be its synonym tricuspidatus, however, regarded by Mörch as a Mediterranean species as opposed to the Atlantic tridentatus; all other taxa have been referred to a variety of genera, Pomatoleios, Pomatoceros, Spirobranchus, but also Galeolaria, Bathyvermilia, Janita, Vermiliopsis and even maybe Hydroides. Nevertheless, the genus including subsequently described or resurrected species is badly in need of revision. [details]
