Material examined
RV Marion Dufresne cruises:
SOUTHERN OCEAN: 1 spec., specimen used for illustrations, cruise MD42 (SIBEX), stn 22-CP66, Prydz Bay, 66°55ʹ45″ S, 74°04ʹ11″ E, depth not given [Google Earth depth for that position: 427 m (accessed 27 Sep. 2016)], 26 Jan. 1985 (MNHN-IU-2014-4265) [extraction M24; Genbank nr, COI: KU870887]; 1 spec., previously identified as Epimeria grandirostris, cruise MD42 (SIBEX), stn 22- CP73, Prydz Bay, 66°57ʹ25″ S, 72°41ʹ24″ E, depth not given [Google Earth depth for that position: 540 m (accessed 27 Sep. 2016)], 26 Jan. 1985 (MNHN-IU-2014-4256).
Diagnosis
Morphology unique in the genus Epimeria. Pereionite 2 with small but broad posterodorsal tooth; pereionite 3 to pleonite 3 laterally sculptured, with tridimentionally sculptured and medially notched mid-dorsal tooth. Posteroventral border of coxa 4 very concave, surface just in front of this border forming a very deep groove.
Colour pattern
Red with on each side a broad white longitudinal stripe running along the upper part of the coxae (Coleman 2007: plate 2 fig. e) or blood red with white patches (Lörz & Coleman 2009: unnumbered photograph p. 17).
Distribution
Western Ross Sea, 337–474 m (Watling & Holman 1980); Prydz Bay, 427–540 m (present material).
