Eunice suviensis (Treadwell, 1922)

Leodice suviensis Treadwell, 1922:138–139, figs. 12–16, pl. 2: figs. 8–13.

Eunice afra.—Hartman, 1956:282 [in part, not Eunice afra Peters, 1854].

COMMENTS ON MATERIAL EXAMINED.—The type is no longer available in AMNH. The following notes are based on Treadwell's description.

DESCRIPTION.—Total length 370 mm; maximum width 9 mm.

Eyes dark, lateral to bases of A-II. Antennae in a horseshoe. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles without articulations. A-III to setiger 1; other antennae slightly shorter. Peristomial cirri to middle of anterior peristomial ring, without articulations.

Maxillary formula 1+1, 5+5, 7+0, 6+8, and 1+1; Mx III short; forming an arc with left Mx IV.

Branchiae present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 9 through 160 segments (however, as total number of setigers was not mentioned, the fraction of branchiated setigers cannot be estimated). Maximum number of filaments 9. Branchial stems long and slender. Filaments slender and digitiform, very much longer than short, tapering notopodial cirri.

Ventral cirri inflated from about setiger 10 at least through setiger 50. Posterior ventral cirri without basal inflation. Notopodial cirri short and tapering in all setigers, without articulations.

Pectinate setae slightly flaring with 1 long marginal tooth, with 16 teeth. Shafts of compound falcigers inflated. Appendages short with both teeth well developed and directed obliquely distally. Guards symmetrically rounded; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae and subacicular hooks “very black.” Aciculae tapering and distally blunt, presumably straight. Subacicular hooks tapering with large, laterally directed proximal teeth and erect, smaller distal teeth.

UNKNOWN MORPHOLOGICAL FEATURES.—Most prostomial and peristomial features; parapodial features.

EXPECTED STATE OF SELECTED UNKNOWN FEATURES.—None.
