diagnosis
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]. References. Bartsch (1993 b), Newell (1984). Depository. USNMNHW.
