Comprehensive Description

provided by Smithsonian Contributions to Zoology
Eunice goodsiri (McIntosh, 1885)

Marphysa goodsiri McIntosh, 1885:299–301, figs. 56–58, pl. 38: figs. 6–8, pl. 19A: figs. 18–20.

DESCRIPTION.—No material is available. The following description is based on McIntosh's description and interpretation of his illustrations.

Maximum width 2.5 mm.

Median sulcus deep. Eyes present. Antennae similar in thickness. Ceratostyles tapering, articulated with distal articulations drop-shaped. Length of A-II and A-III similar. Peristomial cirri to anterior end of peristomium.

Maxillary formula (after McIntosh, 1885:300 and fig. 56) 1+1, 4+4, 3+0, 3+6, 1+1.

Branchiae present, palmate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 25 or 26 to end of fragment. First 11 pairs single filaments, maximum 2 filaments continued to end of fragment.

Median acicular lobes conical; aciculae emerging close to midline. Pre- and postsetal lobes unknown. Ventral cirri inflated in median setigers (at least in setigers 20 and 40). Notopodial cirri tapering in all setigers present, without articulations.

Limbate and pectinate setae unknown. Shafts of compound falcigers distally inflated, without marginal serrations, with internal striations. Appendages tapering, bidentate. Proximal teeth larger than distal teeth, tapering, directed laterally. Distal teeth tapering, curved, distally directed obliquely laterally. Guards of compound falcigers distally symmetrically rounded, marginally smooth; mucros absent. Pseudocompound falcigers and compound spinigers absent. Up to 3 aciculae in anterior setigers, single in median setigers (setiger 40), dark, pointed, bent in anterior setigers. Subacicular hooks with dark core and clear sheath, bidentate. Distribution unknown, single. Proximal teeth larger than distal teeth, directed laterally, tilted upward distally. Distal teeth short, thick, tapering, directed distally.

UNKNOWN MORPHOLOGICAL FEATURES—Most features remain unknown.

EXPECTED STATES OF SELECTED UNKNOWN FEATURES.—Species too poorly known to allow any predictions.

CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 34, 56. Unknown Characters: 1, 2, 4–8, 10–12, 14–16; 18, 19, 24–26, 28, 29, 36–38, 40, 45–52, 57–60, 63, 65–68, 80.
