Lohmannella reducta Bartsch, 1986

Diagnosis. Two corneae present. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. Two dorsal setae on PE. Female with 29–33 Pgs and 6 Sgs. Male with 64 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 6-6-4-3 setae; Gn I–IV with 7-7-4-4 setae, 3-0-0-0 Bp setae; Tb I–IV with 9-8-5-5 setae, 4-2-1-2 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2-1-2-1 Bp setae. Lc I with unidentate accessory process. Idiosoma length 318–335 in female, 278 in male, 254–260 in DN. Idiosoma width 223–241 in female, 235 in male. Gnathosoma length 167–173 in female, 155 in male, 133–136 in DN. Ratio of gnathosoma to idiosoma 0.51–0.54 in female, 0.56 in male, 0.51–0.54 in DN. Ratio of P-2 to P-1 4.00.

Remarks. This species was originally described under the name of L. steueri reducta . Therefore, this species is similar to L. steueri . However, L. reducta differs from the latter in having Tb I and Tb II with 4 and 2 Bp setae, respectively. Female, male, and DN are known.

Habitat. Sublittoral zone: Sediment at 20–40 m depth.

Distribution. Mediterranean: Port Miou, Port Pin (Golfe du Lion) [ France].
