Remarks.

The identity of the E. puncticulata illustrated by colour photographs in the books of Coleman (2007: plate 2 figure d) and Rauschert & Arntz (2015: plate 55) is not clear. The photograph examined are not sharp enough to reveal all relevant details. The species is similar to E. iota sp. nov., E. teres sp. nov., E. puncticulata and E. urvillei sp. nov. Unlike E. iota sp. nov., E. teres sp. nov. and E. urvillei sp. nov., E. ( Subepimeria) sp. 2 exhibits a distinct brown stripe on each side of pereionite 4 and on coxa 4. The colour pattern of E. puncticulata s. str. is unknown. The collection details of the specimen of Rauschert & Arntz (2015) is given in an early draft of their book made available to the authors: ANT-XVII/3 stn 138 [138-1]. The coordinates of this station are: 71°08.90ʹ S, 013°12.80ʹ W to 71°08.80ʹ S, 013°13.20ʹ W [eastern shelf of the Weddell Sea], 765– 840 m.
