(Scale bars in mm.)
NUMBER 523 313 Eunice stigmalura is listed with similar species in Tables 46 and 48. It is also listed in Tables 22 and 23 among species with bidentate subacicular hooks. The thick, blunt distal teeth in the subacicular hooks present in part of the material make the species by definition a member both of groups A-2 and C-2, even if all other characters suggest that it to be a member of C-2 only. The separation between anterior and posterior rings of the pcristomium is distinct on all sides in E. stigmatura and E. havaica. In E. havaica A-111 is distinctly longer than A-II; in E. stigmatura they are similar in length. Of the three species in Table 23 with long, cylindrical articulations in the ceratostyles, E. johnsoni has short peristomial cirri; in E. gracilicirrata and E. stigmatura the peristomial cirri reach at least the middle of the prostomium. In E. gracilicirrata the branchiae clearly outreach the notopodial cirri; in E. stigmatura they are of about the same length. Eunice stragulum Grube, 1878 Eunice stragulum Grube, 1878b:163-164. Marpkysa stragulum.—Crossland, 1903:136. REMARKS.—This species was described in detail and listed by Grube in what he recognized informally as section Marphysa within the genus Eunice. It was formally transferred to Marphysa by Crossland and will be treated in a forthcoming review of that genus. Eunice subdepressa Grube, 1866 Eunice subdepressa Gnibe, 1866b:68; 1878a:101. REMARKS.—Described from Puerto Cabello, Venezuela, this species was characterized as having branchiae starting on setiger 24 and continued to end of the fragmented specimen (203 setigers). Maximum number of branchial filaments is four and A-II I does not reach beyond the peristomium. The listing in Grube (1878a: 101) implies that the antennae lack articulations. The information is clearly inadequate to characterize the species; no specimen is available and the species is here considered indeterminable. 185. Eunice suviensis (Treadwell, 1922) TABLES 27,28 Leodice suviensis Treadwell, 1922:138-139, figs. 12-16, pi. 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. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 58, 59. Unknown Characters: 1, 4-12, 16, 17, 20, 24-26, 28, 29, 37-40, 42-52, 54-56, 60, 65,67, 74, 78, 80-82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—37,1; 38,1. REMARKS.—The shape of the subacicular hooks, branchial distribution, and development of branchiae indicate that the synonymy proposed by Hartman (1956) cannot be correct. The species was well characterized, but not sufficiently to be included in the key; it is compared to similar species in Tables 27 and 28. Compared to other species with short antennae and bidentate subacicular hooks listed in Table 28, E. suviensis has slender, tapering notopodial cirri, rather than medially or basally strongly inflated ones. New material from Rat Passage, Suva Harbor, from which it was originally described, should be examined to establish features that cannot be determined from original description.
