Figure 136.—Male, P5; sample 20; scale D. female (1.45 mm), sample 25; 1 female (1.47 mm), sample 26; 1 female (1.68 mm), sample 30; 1 female (1.95 mm) and 1 male (1.90 mm), sample 31; 1 female (1.85 mm), sample 33. Description PI Ri with 2 inner setae; P2 Ri2 with 1 outer seta. Female.—Length 1.40-2.4 mm. Prosome in dorsal view ovoid, head slightly truncate. In lateral view with fairly abrupt forward slope. Th4 and Th5 separate; Th5 lateral corners rounded, not prolonged; Thl-Th4 without lateral spinules. Prosome/urosome ratio variable; prosome 3-4 times urosome. Genital segment as long as wide, protruding ventrally one-half depth of rest of urosome. Caudal rami as long as wide, symmetrical. Caudal setae symmetrical. Al exceeding caudal rami by about 2 segments; ter- minal segments (Fig. 157) of moderate length and width. Most segments damaged on material studied. A2 Rel with 2 setae. Mx2 posterior surface of lobe-5 base apparently without spines. Mxp (Fig. 130) with typical number of setae; Bl surface with few rows of setules. B2 with transverse spine-comb about one-third length on outer surface; inner longitudinal row of stiff hairs. Ri4-5 outer setae nude, bladelike, tapering toward each end; not as shown by Sars (1901). Ri5 with inner spinules. PI similar to that in S. elongatus, Re3 posterior sur- face without spines. Sars' (1901) figure lacks 1 inner seta on Re3. P2 (Fig. 131) Bl outer surface with few spinules; in- ner posterior surface with setules. P3 Bl outer surface with few setules, spinules, and weak spines; inner 54
