Perkinsiana Knight-Jones 1983
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 Chamber...

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.

In this study, Perkinsiana antarctica (Kinberg, 1867) and Perkinsiana assimilis (McIntosh, 1885) are redescribed and reported for several localities off Uruguay, Argentina and Chile.

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.
