Description PI Ri with 3 inner setae; P2 Ri2 with 1 outer seta. Female.—Length mm (Figs. 45, 46). Prosome in dorsal view robust ovoid, in lateral view with abrupt, even forward slope. Th4 and Th5 separate; Th5 lateral corners prolonged, variable, reaching about midgenital segment. Thl-Th4 without lateral spinules. Prosome length 4Vi times urosome. Area of attachment proximal to genital segment with dorsal spinules. Genital segment slightly wider than long, protruding ventrally one-third depth of rest of urosome; genital segment relatively opaque, masking internal structure; genital field (Fig. 43) apparently similar in all Spinocalanus species. Supra-anal plate with row of spinules. Caudal rami about as long as wide, left ramus longer and wider than right. Caudal setae also asymmetrical: left terminal seta second. 30.
