Notopodial articulations Pectinate setae No. of pectinate teeth Shaft of compound falcigers Acicular color Subacicular color No. of subacicular teeth Core-sheath construction N=4 visible on all sides middle of prostomium 3 3 absent tapering; flat 5 inflated yellow yellow 3 indistinct superiorly; these sections wrapped around superior edge of acicular lobes and terminating on front of acicular lobes approximately at midline, covering emerging aciculae. Remainder of postsetal lobes following outline of acicular lobes closely. High sections located inside presetal lobes on anterior face of parapodia, reaching well beyond acicular lobes. First 4 ventral cirri tapering and blunt-tipped. Ventral cirri basally inflated from about setiger 5 through setiger 25. Inflated base ovate and very distinctly set off from large, tapering narrow tips. Bases of ventral cirri merge into body wall posterior to setiger 25, in posterior setigers only tapering, blunt tips of ventral cirri retained. Anterior notopodial cirri basally slightly inflated, tapering distally to slender, digitiform tips. Posterior notopodial cirri reduced in length to ~ x li of length in anterior setigers, tapering from base. Notopodial cirri without articulations. Limbate setae nearly capillary with very indistinct limbation, relatively thick with short, tapering tips, marginally very finely pilose. All pectinate setae (Figure 115c,h) very small, tapering, flat One marginal tooth very thick and long; ~5 teeth present. Anterior pectinate setae slightly larger than posterior ones. Shafts of compound falcigers (Figure 115b,g) inflated with distinct distal beak, marginally coarsely serrated. Anterior appendages slightly longer than posterior ones, and slightly less tapering, bidentate. Proximal teeth narrowly triangular and directed slightly basally. Distal teeth distinctly shorter than proximal teeth, bent and directed laterally, thick and relatively blunt in posterior setigers, slender and tapering in anterior setigers. Anterior guards tapering to sharp, symmetrical tips, but not mucronate. Posterior guards symmetrically rounded, all guards marginally finely serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae (Figure 115i) paired, tapering, clear yellow; tips distinctly bent ventrally; cross-sections round. Dorsal aciculae in posterior setigers with short, pointed guards. Separation between core and sheath indistinct in both aciculae and subacicular hooks. Subacicular hooks (Figure 115f) yellow, tridentate with teeth in a crest. Hooks first present from setiger 20-22, present in all setigers thereafter; multiple hooks in most setigers. UNKNOWN MORPHOLOGICAL FEATURES.—None. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: None. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice vittata is listed with similar species in Tables 41 and 42. The relationship between this species and other species with multiple subacicular hooks and articulated ceratostyles was indicated in the remarks to E. indica. Eunice vittata has been reported from all over the world. Most of these reports probably are of related species, including the species listed in Table 42.
