Eunice bicirrata Rullier, 1964

Eunice bicirrata Rullier, 1964:178–180, fig. 15a-h.

COMMENTS ON MATERIAL EXAMINED.—This species was described from a single specimen from the Cape Verde Islands in 120–150 m depth. The specimen was not available; the description below is summarized from the original description.

DESCRIPTION.—Holotype (and only specimen) incomplete, with 50 setigers; total length 12 mm; maximal width 1 mm.

Ceratostyles slender and digitiform, articulated, especially distally, with long, cylindrical articulations, becoming apparently drop-shaped distally. A-III to setiger 10. Two pairs of peristomial cirri present; outer pair to posterior end of prostomium; medial pair somewhat shorter.

Branchiae present, palmate. Branchiae from setiger 3 through setiger 48. Maximum number of filaments 2.

Limbate setae illustrated as marginally smooth. Pectinate setae absent. Shafts of compound falcigers inflated. Appendages small, linear, bidentate. Proximal teeth triangular; distal teeth slender, curved. Guards illustrated as symmetrically sharply pointed, but not mucronate. Pseudocompound falcigers and compound spinigers absent. Aciculae yellow, tapering to blunt tips and distally curved. Subacicular hooks yellow, tridentate with teeth in a crest. Hooks first present from setiger 45. Two distal teeth emerging from common base.

UKNOWN MORPHOLOGICAL FEATURES.—Shape features associated with pro- and peristomium; jaw structure (but see comments below); all parapodial features; setal distribution and shapes must be confirmed; pygidium and anal cirri.

EXPECTED STATES OF SELECTED UNKNOWN FEATURES.—The species is too poorly known to make meaningful predictions.

CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: None known. Unknown Characters: 1, 2, 4–19, 24–26, 28, 29, 32–34, 37–68,74, 75, 78,81,82.

ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—None.
