Description
Lohmannella kerguelensis Lohmann, 1907
Diagnosis. One cornea present. Glp-1 anterior to Ds-1. Ds-2 on membranous cuticle. Ds-3 on margin of PD. Two dorsal setae on PE. Male with ca.56 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 8-7-(6,7)-4 setae; Gn I–IV with 8-9-4-4 setae, 4-4-1-1 Bp setae; Tb I–IV with 14-(12,13)-11-10 setae, 7- 6-6-5 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2-2-(2,3)-(2,3) Bp setae. Lc I with unidentate accessory process. Idiosoma length 420–453 in male. Idiosoma width 322 (idiosoma length 453) in male. Gnathosoma length 310–320 in male. Ratio of gnathosoma to idiosoma 0.71–0.74. Ratio of P-2 to P-1 3.63.
Remarks. This species was originally described under the name of L. gaussi var. kerguelensis. Thereafter, Newell (1984) regarded this variety as a distinct species. The specis resembles other two Antarctic species (L. fukushimai and L. gaussi) in having 7 pectinate setae on Tb I. However, L. kerguelensis is separated from the latter 2 species by its shorter gnathosoma, lacking of porose areolae, and the absence of the spinelet-replaced Glps. Female and male are known.
Habitat. Littoral–Sublittoral zones: Crevices, colonial organisms, algal tufts, sediments at a depth of 49–58 m.
Distribution. Indian Ocean: Kerguelen Is. [France]. Arctic Ocean: Palmer Archipelago [US].
