Lohmannella nudipes Bartsch, 1977

Diagnosis. Two corneae present. Glp-1 posterior to Ds-1. Ds-2 on AD. Ds-3 on membranous cuticle. Two dorsal setae on PE. Female with 31 Pgs and 8 Sgs. Tr I –IV with 1-1-1-1 setae; Bf I –IV with 3-4-2-2 setae; Tf I –IV with 8-6-6-5 setae; Gn I–IV with 6-5-4-4 setae, 1-0-0-0(?) Bp setae; Tb I–IV with 10-9-7-7 setae, 5-5-3-3 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 0-0-0-0 Bp setae. Lc I smooth, without accessory process. Idiosoma length 390 in female. Idiosoma width 279 in female. Gnathosoma length 182 in female. Gnathosoma width 95 in female. Ratio of gnathosoma to idiosoma 0.47.

Remarks. This species is distinguished from the congerners by the absence of ventral setae on all tarsi. This may be an euryhaline species ( Bartsch 1977b). A single female is known.

Habitat. Littoral zone: Intertidal sediment in estuary.

Distribution. North Atlantic Ocean: Penzé River (Roscoff) [ France].
