<paragraph pageId="56" pageNumber="57">Holotype (MNHN 1551) with body pinkish anteriorly, whitish medially and posteriorly, clean with sparse, small filamentous papillae covering most of body (Fig. 19A). Larger, thin papillae along the dorsal surface of last few segments and surrounding shield but not arranged in rows. Body 11 mm long, 3 mm wide, 32 segments.</paragraph>
|
|
<paragraph pageId="56" pageNumber="57">Prostomium projected, blunt conical (Fig. 19A, B). Peristomium rounded, equalized to the position of mouth, with abundant papillae extended behind prostomium. Mouth circular, extends from base of prostomium to anterior edge of first chaetiger.</paragraph>
|
|
<paragraph pageId="56" pageNumber="57">First three chaetigers with 12-14 bright bronze recurved, spatulate hooks, without subdistal dark areas (Fig. 19B). Genital papillae protrude ventrally from body wall between segments 7 and 8. Pre-shield region with 8 segments, with single lateral bundles of about 2 capillary chaetae, protruding from body wall along segments 9-10.</paragraph>
|
|
<paragraph pageId="56" pageNumber="57">Ventro-caudal shield brick red, papillose, with ribs faintly defined but no concentric lines, nor sediment particles; suture extended throughout shield. Anterior margins rounded; anterior depression shallow; anterior keels not exposed. Lateral margins rounded, expanded medially, reduced posteriorly. Fan truncate, barely projected beyond posterior shield corners (Fig. 19A, C), margin smooth, with a median and two smaller lateral notches.</paragraph>
|
|
<paragraph pageId="56" pageNumber="57">Marginal shield chaetal fascicles include 10 lateral ones, chaetae in oval arrangement, and 10 posterior fascicles, chaetae in oval arrangement. The 11th lateral fascicles include one or two fine capillary chaetae, four times as long as others. Posterior fascicles positioned close to midline. Peg chaetae broken; additional delicate capillary chaetae between lateral and posterior fascicles present.</paragraph>
|
|
<paragraph pageId="56" pageNumber="57">Branchiae few, emerging from a distinct plate; branchial area (observed in paratype) covered with very thin, long interbranchial papillae, increasing in density towards margin of ventro-caudal shield (Fig. 19E).</paragraph>

<paragraph pageId="56" pageNumber="57">Both the paratype and additional specimen have their introvert invaginated. Their shields show progressive enlargements of the anterior margins and the fan, with the median and lateral notches becoming more pronounced (Fig. 19D), and the shield taking a more elongate outline.</paragraph>

the anterior margin is barely projected forward and the posterior margin has a median notch, but no lateral notches. There are other differences regarding the relative number of shield chaetal fascicles, but because of chaetal fragility, they are less reliable.
