Scaptognathus meteorensis Bartsch, 2003

Diagnosis. Glp-1 same level as Ds-1. Ds-2 and Ds-3 on membranous cuticle. PE with 1 dorsal seta. GA bipartite in female and male. Female with 6 Pgs and 4 Sgs. Male with 21 Pgs and 6 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 2-2-1-1 setae; Tf I–IV with 5-4-2-2 setae, 2-0-0-0 Bp setae; Gn I–IV with 4-5-3-3 setae, 2-1-0-0 Bp setae; Tb I–IV with 9-6-7-7 setae, 6-3-4-4 Bp setae; Ta I–IV with 3-3-3-3 dorsal setae, 1-1-0-0 Bp setae. Lc I almost smooth. Idiosoma length 202–215 (holotype 215) in male, 222 in female. Idiosoma width 137 in male (holotype). Gnathosoma length 167 in male (holotype). Gnathosoma width 77 in male (holotype). Ratio of gnathosoma to idiosoma 0.78 in male (holotype). Ratio of P-2 to P-1 5.0 (holotype).

Remarks. This species is similar to S. minutus , however, different from the latter in the AD with broadly arched posterior margin and PD extending far beyond Ds-6. A larva described under the name of “ Scaptognathus sp. A ” in Bartsch (1973b) is likely to be this species ( Bartsch 2003b). Male, female, and LV are known.

Habitat. Bathyal zone: Sediment at 332 m depth.

Distribution. North Atlantic Ocean: Great Meteor Seamount.
