Summary:Scaptognathides minor Bartsch 1996 Diagnosis. Ds-2 and Ds-3 on AD. OC with 2 Glps. Female with 4 Pgs, without Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 2-2-2-2 setae; Tf I–IV with 5-5-2-2 setae; Gn I–IV with 4-4-3-3 setae; Tb I–IV with 5-5-5-5 setae; Ta I–IV with 3-3-3-3 dorsal setae. Idiosoma length 157–165 in female (holotype 160). Lc II–IV with unidentate accessory process and comb. Idiosoma width 97 in holotype female. Gnathosoma length 72 in holotype female. Gnathosoma width 40 in holotype female. Ratio of gnathosoma to idiosoma 0.45. Remarks. The species is characterized by foveate dorsal plates, lack of Sgs in female, and Ta III with 3 dorsal setae. This species is similar to S. hawaiiensis, however, distinguishable from the latter by the lack of Sgs in female and the presence of 2 Glps on OC. Female is known. Habitat.
