Scaptognathus pauciporus Bartsch, 1977

Diagnosis. Glp-1 posterior to Ds-1. Ds-2 on membranous cuticle. PE with 1 dorsal seta. GA bipartite in female and male. Female with 6 Pgs and 4 or 6 Sgs. Male with 22–26 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 (4,5)-3-2-2 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 8-6-7-7 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 with unidentate accessory process. Idiosoma length 222–248 in female, 202–233 in male, 174–194 in DN, 145–150 in PN, 120–127 in LV. Idiosoma width 147 ( idiosoma length 219) in female, 140 ( idiosoma length 204) in male. Gnathosoma length 174 ( idiosoma length 219) in female, 150 ( idiosoma length 204) in male. Gnathosoma width 95 ( gnathosoma length 174) in female. Ratio of gnathosoma to idiosoma 0.74–0.79.

Remarks. This species is similar to S. pacificus , however, distinguished from the latter by the number of Bp setae on the legs and the ornamentation of the dorsal plates. Female, male, DN, PN, and LV are known.

Habitat. Littoral zone: Sediment at littoral zone.

Distribution. South Pacific Ocean: Fernandina, Isabela, Tower, Santa Cruz, Barrington, Floreana, San Cristobal (Galapagos Is.) [ Ecuador].
