C. d’Udekem d’Acoz and M. Verheye (RBINS, INV. 122943) [extraction ANT 38 (largest specimen); Genbank nr, COI: KU870824, 28S: KU759597 and ANT 39 (smallest specimen); Genbank nr, COI: KU870825, 28S: KU759598].
RV Aurora Australis cruises:
SOUTHERN OCEAN: 1 spec., cruise CEAMARC, sample CEAMARC 1295, stn 51AEV215, Adélie Coast, 66°44ʹ52″ S, 145°26ʹ40″ E, 525–553 m, beam trawl, 30 Dec. 2007, coll. IPEV-AAD-MNHN (MNHN-IU-2016-6559); 1 spec., cruise CEAMARC, sample CEAMARC 1317, stn 51AEV215, Adélie
Coast, 66°44ʹ52″ S, 145°26ʹ40″ E, 525–553 m, beam trawl, 30 Dec. 2007, coll. IPEV-AAD-MNHN (MNHN-IU-2014-4276) [extraction M19); Genbank nr, COI: KU870885, 28S: KU759668].
Colour patternBody and appendages whitish to colourless, semi-translucent; dorsal part of body orange; eyes orange; oral field and tip of gnathopods blood red.
Body lengthUp to 28 mm.
DistributionSouth Orkney Islands; South Shetland Islands; Antarctic Peninsula; eastern shelf of the Weddell Sea; Davis Sea; Adélie Coast, Ross Sea; 0–1200 m (Coleman 2007; present data). As many records of E. macronyx come from pelagic nets (De Broyer et al. 2007; present data), and as the species is very slender with large eyes reminiscent to those of hyperiids, it is obviously a true pelagic species.
