22 mm ( Coleman 2007).
White with scarce suffusions of orange; eyes reddish (photograph of Rauschert & Arntz 2015 as ‘ Epimeria inermis 1’).
Magellanic Region: Patagonia, Falkland Islands, 27–494 m ( De Broyer et al. 2007), Burdwood Bank, 296–299 m (see remarks).
The specimen labelled ‘ Epimeria inermis 1’ in Rauschert & Arntz (2015) does not correspond to the description of E. inermis: it exhibits important differences in the shape of coxa 4, and the dorsal profiles of pleonite 3 and urosomite 1. The morphology of this specimen is more similar to E. acanthurus as illustrated by Coleman (2007), and it is therefore identified as such. Rauschert & Arntz (2015) do not indicate the collection details of their specimen, but this information was found in an early draft of their book made available to the authors: ANT XIX [obviously ANT-XIX/5], LAMPOS, station 153 [i.e., 153-1]. The coordinates of this station are: 54°32.75ʹ S 56°09.84ʹ W to 54°31.22ʹ S 56°08.93ʹ W [Burdwood Bank], 296– 299 m.
