Description

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).
