Diagnosis. Two corneae present. Glp-1 same level as Ds-1. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. Two dorsal setae on PE. Female with 18–24 Pgs and 8 Sgs. Male with 60–74 Pgs and 8 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 3-3-(3,4)-3 setae; Tf I–IV with (8–10)-(6–8)-6-4 setae; Gn I–IV with 8-(7,8)-(4,5)-(4–6) setae, 4-?-?-? Bp setae; Tb I–IV with 14-12-11-10 setae, 7-6-6-5 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2- 2-(3,4)-3 Bp setae. Lc I with unidentate accessory process. Idiosoma length 495–560 in female, 520–582 in male, 408–489 in DN. Idiosoma width 340 (idiosoma length 500) in male, 324 in DN. Gnathosoma length 510–560 in adults. Ratio of gnathosoma to idiosoma 0.95–1.00. Ratio of P-2 to P-1 7.20.
Remarks. The most obvious characteristics are: the gnathosoma almost as long as idiosoma, Tb I with 7 ventral Bp setae, Glp small and partly replaced by spur-like setae, and long slender legs. The southern hemisphere species have large Glps in general (Newell 1984, Bartsch 1993b). This species is different from northen hemisphere species in having Glps replaced by setae. Female, male, and DN are known.
Habitat. Sublittoral–Bathyal zones: This species might inhabit soft surficial sediments at 190–820 m depth.
Distribution.Antarctic Ocean: Off Pr. Harald Coast (68°53’S, 30°56’E), Western Weddell Sea (Atka Bay, Kapp Norvegia, Halley Bay), Western Ross Sea [Antarctica].
