Scaptognathus minutus Bartsch, 1973 Diagnosis. Glp-1 posterior to Ds-1. PE with 1 dorsal seta. GA bipartite in female. Female with 6 Pgs and 4 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 1-1-1-1 setae; Tf I–IV with 6-5-3-3 setae, 2-0-0-0 Bp setae; Gn I–IV with 4-4-3-3 setae, 2-1-0-0 Bp setae; Tb I–IV with 10-6-6-7 setae, (5,6)-3-(3,4)-4 Bp setae; Ta I–IV with 3-3-3-3 dorsal setae, 1-1-0-0 Bp setae. Lc I with very delicate accessory process. Idiosoma length 145–178 in female, 109–157 in DN, 90–102 in PN, 94 in LV. Idiosoma width 118 (idiosoma length 153) in female. Gnathosoma length 136 in female, 101–113 in DN, 96 in PN, 80 in LV. Gnathosoma width 72 in female. Ratio of gnathosoma to idiosoma 0.85–0.89 in female. Ratio of P-2 to P-1 2.50. Remarks. The outstanding characteristics of this species are: the small body size, circular pars membranosum embedded within the pars sclerosum, and almost smooth Lc. Female, DN, PN, and LV are known. Habitat. Sublittoral–Bathyal zones: Sediment at 216–770 m depth. Distribution. North Atlantic Ocean: Josephine Seamount, Great Meteor Seamount, Lost City (Mid-Atlantic Ridge).
