Styelidae Cnemidocarpa acanthifera Monniot n. sp. (Figures 17–18) Station 80: 820 m. Ethymology: in Greek acantha = spine. The holotype fixed in alcohol, 15 mm in body length, has a short narrow peduncle ending in rhizoids (Fig. 17 B), a naked tunic, except a belt of tunic filaments at 1/3 of the body length at the base of the siphons (Fig. 17 B). Both siphons are long, close to each other with a cross-shaped opening. Thicker on the siphons, the tunic is paper-like elsewhere and adheres to the body wall. The internal lining and the external surface of the siphons are covered with dense spinules. The spinules (Fig. 17 A) are 120 µm long and sharp reminding of those of the Pyuridae family. The body wall (Fig. 18 C) is entirely filled with dense transverse and longitudinal muscle fibres regularly distributed. Few short oral tentacles (Fig. 18 B) in two orders of size are inserted at the base of a thick blade; this membrane has minute folds resulting in a scalloped image (Fig. 18 B). The dorsal tubercle is erect ... : Published as part of Monniot, Françoise, Dettai, Agnès, Eleaume, Marc, Cruaud, Corinne & Ameziane, Nadia, 2011, Antarctic Ascidians (Tunicata) of the French-Australian survey CEAMARC in Terre Adélie, pp. 1-54 in Zootaxa 2817 on pages 27-34, DOI: 10.5281/zenodo.277174 ...
