Description

Lohmannella norvegica Viets, 1927

Diagnosis. Two corneae present. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. One dorsal seta on PE. Female with 28(?) Pgs and 8 Sgs. Gn I with 1 Bp seta; Tb I with 6 Bp setae; Ta I–IV with 1-1-2-1 Bp setae. Lc I with unidentate accessory process. Idiosoma length 425–434 in female. Idiosoma width 310 in female. Gnathosoma length 204–205 in female. Ratio of gnathosoma to idiosoma 0.47–0.48 in female. Ratio of P-2 to P-1 3.00.

Remarks. This species closely resembles L. kervillei. However, L. kervillei has PD with sharrow ramp-like process posteriory. Female is known. Type specimen is hard to examine due to deterioration. The records of this species from UK by Pugh & King (1985) should belong to L. kervillei (Somerfield 1991, Bartsch 2020).

Habitat. Littoral–Sublittoral zones: Algae (Laurencia pinnatifida (Rhodophyta), Fucus serratus, Laminaria digitata (Phaeophyta)), barnacles (Semibaranus balanoides), sediment (stone-corals) at 150 m depth.

Distribution. North Atlantic Ocean: Sten Sund, Nordre Brattholmen (Bergen) [Norway].
