Scaptognathus newelli Bartsch, 1988 Diagnosis. Glp-1 same level as Ds-1. Ds-2 on membranous cuticle. PE with 1 dorsal seta. GA tripartite in female and male. Membranous part surrounded by GA. Female with 4 Pgs and 4 Sgs. Male with 11 Pgs and 6 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 1-1-1-1 setae; Tf I–IV with 4-3-2-2 setae, 1-0-0-0 Bp setae; Gn I–IV with 5- 4-2-3 setae, 2-1-0-0 Bp setae; Tb I–IV with 6-5-5-5 setae, 3-2-2-2 Bp setae; Ta I–IV without Bp setae. Lc I with unidentate accessory process. Idiosoma length 188 in female, 183 in male. Idiosoma width 114 (idiosoma length 188). Gnathosoma length 126, width 51 in female. Ratio of gnathosoma to idiosoma 0.68. Ratio of P-2 to P-1 3.60. Remarks. The conspicuous character of this species is the tripartite GA that consists of membranous area and punctated sclerites in both female and male. This species was originally described by Newell (1984) under the name of S. punctatus [junior homonym]. Female and male are known. Habitat. Littoral zone: Coarse sands and shell fragments at intertidal zone. Distribution. South Pacific Ocean: Viña del Mar [Chile]. References.
