Scuticoxifera

 Dorsal and lateral figures of female Tainisopus fontinalis, from here.

Belongs within: Isopoda.
Contains: Oniscidea, Valvifera, Sphaeromatidea, Limnoriidea, Cymothoida.

The Scuticoxifera are a major clade within the isopods, uniting the oniscideans, valviferans, anthuroideans, and the polyphyletic ‘flabelliferans’.

Synapomorphies (from Brandt & Poore 2003): Coxae I-VII transformed into plates in contact with entire length of tergite; penes medial on pereonite VII; anterior filter channels of stomach curving laterally or in transverse position (except Anthuroidea).
