Description

Lohmannella kervillei (Trouessart, 1894)

Diagnosis. Two corneae present. Glp-1 posterior to Ds-1. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. One dorsal seta on PE. Female with 26–34 Pgs and 8 Sgs. Male with ca.66 Pgs and 8 Sgs. Tr I–IV with 1- 1-1-1 setae; Bf I–IV with 3-3-3-2 setae; Tf I–IV with 6-5-4-3 setae; Gn I–IV with 6-6-4-3 setae, 2-1-0-1 Bp setae; Tb I–IV with 11-10-6-6 setae, 6-5-3-3 Bp setae; Ta I–IV with (3,4)-(3,4)-4-3 dorsal setae, 1-1-3-1 Bp setae. Lc I with unidentate accessory process. Idiosoma length 353–447 in female, 340–353 in male, 303–328 in DN, 252–253 in PN, 187 in LV. Idiosoma width 291 (idiosoma length 397) in female, 267 (idiosoma length 340) in male. Gnathosoma length 179 (idiosoma length 397) in female, 167 (idiosoma length 340) in male. Gnathosoma width 102 (idiosoma length 397) in female, 90 (idiosoma length 340) in male. Ratio of gnathosoma to idiosoma 0.45–0.49. Ratio of P-2 to P-1 2.56.

Remarks. The species was originally described by Trouessart & Neuman (1894b) under the name of Leptognathus kervillei. Lohmann (1901) recorded this species in the genus Trouessartella. The species is very similar to L. norvegica. However, the palpi of L. norvegica are distinctly more slender than those in L. kervillei. The records under the name of L. norvegica from UK by Pugh & King (1985) are L. kervillei (Somerfield 1991, Bartsch 2020). A record of this species from 318 m depth in Andre (1946) is in need of verification (Bartsch 2020). Female, male, DN, and LV are known.

Habitat. Littoral–Sublittoral zones: Algae (Laminaria digitata, Laminaria ochroleuca, (Phaeophyta), Corallina spp., Lometaria spp. (Rhodophyta)). Lichina pigmaea (Lichinales). Laminaria holdfasts, crevices in Lithothamnion and Lithophyllum (Rhodophyta), barnacles, mussels, hydroids, bryozoans, sands and gravels among rocks, sediment at 9–318 m depth.

Distribution. North Atlantic Ocean: Ijmuiden [Netherlands]. Grandcamp-les-Bains, Îles St. Marcouf, Cap de la Hague, Pointe du Roc, Granville, Îles Chausey, Roscoff, St. Guénolé (Penmarch), Croisic, Saint-Martin-de-Ré, Vaux-sur-Mer [France]. Mouro Is. (43°28’24’’N, 3°45’22’’W) [Spain]. Scotman’s Bay, Dalkey Is. (Dublin), Ring Head, Carrigathorna (West Cork) [Ireland]. Harwich, Brighton, Weymouth, Downderry (Cornwall), Bracelet Bay (Gower Peninsula), Dale (Pembrokeshire) [UK]. Azores [Portugal].
