(damaged, BL = 7.3 mm); South Shetland area , NNW of Elephant Island, ANDEEP-I station 043-8; 60°27.12ʹ S, 56°05.10ʹ W to 60°27.24ʹ S, 56°05.25ʹ W; depth 3961.2– 3962.4 m; 4 Feb. 2002; EBS epinet GoogleMaps .

Nomenclatorial note

The nominative ‘ Sarsius ’ and the genitive ‘ Sarsii ’ are valid Latinizations of the proper name ‘Sars’. As previously stressed by Wittmann & Chevaldonné (2021) the original ending ‘ ii ‘ought to be maintained according to ICZN (1999), Article 33.4.

Distribution

Type locality not defined. First description by Sars (1884) based on “several” specimens from the Kerguelen Islands, 48°41ʹ S, 69°03ʹ E, depth 219 m, and on one larger mutilated specimen from Challenger station 153 off East Antarctica, 65°42ʹ S, 79°49ʹ E, depth 3030 m, this last specimen doubted by Hansen (1913) and O.S. Tattersall (1955) to pertain to this species. These and subsequent records were made in the Southern Ocean: Kerguelen Islands, South Georgia, Weddell Sea, Drake Passage, South Orkneys, Bransfield Strait, Shetlands Islands, Falkland Islands ( Malvinas) and Beagle Channel, 49– 67° S, 69° E westward to 69° W, depth 75–3962 m (G.O. Sars 1884, 1885; O.S. Tattersall 1955; Siegel & Mühlenhardt-Siegel 1988; Ledoyer 1995; Brandt et al. 1999; San Vicente 2010; Wittmann & Chevaldonné 2021). The record in Murano (1974b) from Japan, Sagami Bay, 35° N, was not accepted by Meland (2004) as belonging to this species. The ANDEEP I samples from deep waters of the Drake Passage, 59– 60° S, 56– 60° W, depth 2372–3962 m, are within previously published acknowledged ranges.

Descriptive notes

Features of eye and antennula as described for P. antarcticum . Anterior margin of eye rudiments lined with minute teeth (scales). Antennular trunk with disto-median lobe armed with three small teeth increasing in size laterally, lobe disto-laterally with three barbed setae. Distal lobe of antennal scale extends beyond tooth on outer margin. Antennal scale extends ⅗ of its length beyond antennular trunk and ⅓ beyond 3-segmented antennal peduncle. Uropods setose all around, no spine; endopod extends ⅐ of its length beyond telson. Proximal third of linguiform telson without spines; distal ⅔ of each lateral margin with nine small subequal spines; terminal margin with pair of paramedian setae flanked by three pairs of large spines.
