Alexandrella sp. 3 Alexandrella australis – Holman & Watling, 1983: 33–37, in part, figs 1–3. — Berge & Vader 2005a: 1330–1332, fig. 1. non Acanthonotozoma australis Chilton, 1912: 205, pl. 2 fig. 19. Distribution This taxon has been recorded once at the following station: RV Islas Orcadas , cruise 575, Stn 54, 57°39ʹ S, 26°00.4ʹ W [South Sandwich Islands], 2380–2609 m (Holman & Watling 1983, Berge & Vader 2005a). Remarks The specimen identified as Alexandrella australis by Holman & Watling (1983) exhibits striking differences with the illustration of the holotype given by Chilton (1912). The carina of urosomite 1 presents a much stronger posterior tooth and deeper anterior notch on the drawing of Chilton (1912) than in that of Holman & Watling (1983). The specimen of Chilton (1912) has a small posterodorsal tooth on pereionite 6, which is missing in the one illustrated by Holman & Watling (1983). The specimen of Chilton (1912) is illustrated as having a more truncated coxa 1 than the one of Holman & Watling (1983). Finally, the posterodistal tooth of the basis of pereiopod 7 looks longer in the specimen of Chilton (1912) than in the one of Holman & Watling (1983). As the conspecificity of the two specimens is questionable, the name Alexandrella sp. 3 is used herein for the one studied by Holman & Watling (1983). : Published as part of d'Acoz, Cédric d'Udekem & Verheye, Marie L., 2017, Epimeria of the Southern Ocean with notes on their relatives (Crustacea, Amphipoda, Eusiroidea), pp. 1-553 in European Journal of Taxonomy 359 on page 177, DOI: 10.5852/ejt.2017.359, http://zenodo.org/record/3855694 : {"references": ["Holman H. & Watling L. 1983.
