Lohmannella gaussi Lohmann, 1907

Diagnosis. Two corneae present. Glp-1 same level as Ds-1. Ds-2 on OC or margin of OC. Ds-3 on PD. Two dorsal setae on PE. Female with 18–24 Pgs and 8 Sgs. Male with 54–62 Pgs and 8 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 3-3-3-3 setae; Tf I–IV with (9–11)-9-(5,6)-(4,5) setae; Gn I–IV with 8-7-4-4 setae, 4-(3,4)-(0,1)-(1,2) Bp setae; Tb I–IV with (13,14)-(12,13)-(10,11)-10 setae, 7-6-6-5 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2- 2-4-(2,3) Bp setae. Lc I with unidentate accessory process. Idiosoma length 430–568 in female, 407–596 in male, 313–365 in DN. Idiosoma width 343 ( idiosoma length 471) in female. Gnathosoma length 380–460 (387 in idiosoma length 471 female) in adults. Ratio of gnathosoma to idiosoma 0.82–0.91. Ratio of P-2 to P-1 5.00.

Remarks. This species is identified on the basis of widened AE, slender gnathosoma and legs, V-shaped porose costae on PD as in L. antarctica, Ds-1 medial to Glp-1, and Ds-2 on OC. Female, male, and DN are known. Nontype specimen is deposited in the Viets Collection (No.5604) in ZIZMH. L. humerosa Newell, 1984 is synonymized with this species (Bartsch 1993b).

Habitat. Sublittoral–Bathyal zones: Soft sandy deposit at a depth of 95–385 m.

Distribution. South Atlantic Ocean: South Sandwich Is. [UK]. Indian Ocean: Marion and Crozet Is. [France]. Antarctic Ocean: Gauss Station, Wilhelm II land, Western Weddell Sea (Kapp Norvegia) [Antarctica].
