Diagnosis. One cornea present. Glp-1 posterior to Ds-1. Ds-2 on membranous cuticle. Ds-3 on PD. Two dorsal setae on PE. Female with 16–18 Pgs and 8 Sgs. Male with 54 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 (7,8)-(7,8)-6-6 setae; Gn I–IV with 8-(7,8)-4-4 setae, 4-?-0-0 Bp setae; Tb I–IV with 12-(10,11)-(7,8)-7 setae, 6-(3-5)-(3,4)-(3,4) Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2-(1,2)-2-(1,2) Bp setae. Lc I with either no or unidentate accessory process. Idiosoma length 430–470 in female, 420–430 in male. Idiosoma width 350 (idiosoma length 447). Gnathosoma length 230–270 in adults. Gnathosoma width 101 (gnathosoma length 267). Ratio of gnathosoma to idiosoma 0.55–0.60 in adults. Ratio of P-2 to P-1 4.17.
Remarks. The species resembles L. reticulata, but differs from the latter in that Glp-3 closer to the lateral margin of OC, Ds-5 close to Glp-4, and basal pair of rostral setae in distal half of the rostrum. Female, male, nymphs (stages are unclear), and LV are known.
Habitat. Littoral–Bathyal zones (0–460 m): Crevices formed by hapteres, colonial organisms (bryozoans, etc.), and stranded Phyllogigas grandifolius (Phaeophyta).
Distribution. Antarctic Onean: Anvers Is. (Palmer Peninsular), Terre Adélie (Pointe Géologie Archipelago), Ross Is. (McMurdo Station) [Antarctica].
