Description
Summary:Alexandrella sp. 1 Figs 338–339 Bathypanoploea schellenbergi Holman & Watling, 1983: 47, in part (not holotype), fig. 9b, 10,? 11f. Bathypanoploea schellenbergi –? Rauschert & Arntz 2015: 79, pl. 72 [ANT-XXI]. Material examined RV l’Astrolabe cruises: SOUTHERN OCEAN: 1 very large spec., cruise REVOLTA III, no station (Dumont d’Urville Sea), Collect_ID: REVO_449, Adélie Coast, 66°38ʹ S, 140°42ʹ E to 66°38ʹ S, 140°40ʹ E, 718–729 m, mud, beam trawl, 20 Jan. 2012, CE-000002100 (MNHN-IU- 2009-2540). Remarks The specimen examined has a mid-dorsal tooth on pereionite 6 in addition to the usual teeth on pereionite 7 and pleonites 1–3. Otherwise, it looks very similar to Alexandrella pulchra. Only minor differences in the form of coxae 1 and 4 were observed. The shape of the eye is similar to that of A. pulchra, but the body and leg pigmentation is less pronounced. A small tooth is also present in the specimen from the continental shelf of the Ross Sea illustrated by Holman & Watling (1983) and a specimen from the eastern Weddell Sea illustrated by Rauschert & Arntz (2015). The latter specimen has much smaller eyes than A. pulchra, and according to an early draft of Rauschert & Arntz’s book, it was collected during the cruise ANT-XXI (obviously ANT-XXI/2), which almost exclusively sampled on the continental shelf.
