Genus Perkinsiana Knight-Jones, 1983 Remarks. The genus Perkinsiana was established by Knight-Jones (1983), in order to accommodate species previously assigned to the genera Demonax Kinberg, 1867 (= Parasabella fide Tovar-Hernández & Harris 2010), Potamilla Malmgren, 1866, and Potamethus Chamberlin, 1919. Fitzhugh (1989) provided a diagnosis slightly modified from that of Knight-Jones (1983) and indicated the genus was not united by any recognized synapomorphies, Capa (2007) amended the genus and, based on a cladistic analysis, she concluded that Perkinsiana is paraphyletic. Tovar-Hernández et al. (2012) amended the generic diagnosis of Perkinsiana, to include the presence of a palmate membrane and radiolar flanges, and three patterns of abdominal notochaetae: type A) chaetae with a broad hood, progressively tapering to distal tips in all chaetigers; type B) with a broad knee, distal ends narrowing abruptly on all chaetigers; and type C) elongate, with a narrow hood. In this study, Perkinsiana antarctica ... : Published as part of Tovar-Hernández, María Ana, León-González, Jesús Ángel De & Bybee, David R., 2017, Sabellid worms from the Patagonian Shelf and Humboldt Current System (Annelida, Sabellidae): Phyllis Knight-Jones' and José María Orensanz's collections, pp. 1-64 in Zootaxa 4283 (1) on page 36, DOI: 10.5281/zenodo.828032 ...
