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]. References.
