<paragraph pageId="25" pageNumber="26">Holotype (ZMUC POL-2157) with pre-shield and shield regions rounded, much wider than anterior region which is elongate, narrow and bent inwards (Fig. 6A, B). Body papillae few, evenly and widely spaced as filaments over most of surface on segments 1-7; fewer, shorter papillae on segments of shield region. Body up to 8.5 mm long, 5 mm wide, about 28 segments.</paragraph>
|
|
<paragraph pageId="25" pageNumber="26">Prostomium almost spherical, pale yellow. Peristomium oval, raised at position of mouth. Mouth small, covered by papillae, positioned between prostomium and anterior border of second segment.</paragraph>
|
|
<paragraph pageId="25" pageNumber="26">First three chaetigers with 10 larger and up to five smaller flat, bronze, closely associated, falcate hooks per bundle, almost traversing each segment (Fig. 7B, C); hooks with shaft milky, median or subdistal area dark, distal portion light gold. One pair of genital papillae protrude ventrally from intersegmental furrow between segments seven and eight. Pre-shield region with 7 segments, with 2-3 fine capillary chaetae protruding laterally from body wall on some segments.</paragraph>

shield ribs barely noticeable, concentric lines not visible; suture poorly defined, apparently extended throughout shield (Fig. 7D). Anterior margins angular; anterior depression deep; anterior keels exposed, with median notch. Lateral margins curved, expanded medially, reduced posteriorly. Fan truncate with two lateral notches and a median, rounded projection, not extended beyond posterior corners, margin denticulated.

<paragraph pageId="26" pageNumber="27">Marginal chaetal fascicles include nine lateral ones, chaetae ovally arranged, and five posterior fascicles, chaetae in evenly spaced straight rows. Peg chaetae translucent, lighter in colour than other marginal chaetae, as long as, or longer than posterior fascicles chaetae. Peg chaetae emerge from under shield on a fleshy cone, with a wide base in cross section. Additional fine, short, capillary chaetae next to peg chaetae, medially to first fascicle of posterior shield chaetae.</paragraph>

sp. n. differs in several features from any other species. The arrangement and sparseness of papillae on the cuticle, a narrow anterior region, milky introvert hooks, long and translucent peg chaetae, hourglass-shaped shield, shield chaetae protruding from a translucent band of cuticle around the shield, and posterior chaetae along the shield in an almost continuous row, are all significant differences. The other species having a shield with a denticulate posterior margin is
