Kirkegaardia serratiseta (Banse & Hobson, 1968) new combination Figure 16 Tharyx serratisetis Banse & Hobson, 1968: 39 –40, Fig. 7 k–l; Hobson & Banse 1981: 553, Fig. 9 m.

Not Monticellina cf. serratiseta : Diaz-Diaz et al. 2014: 357 –358, Fig. 2 f–i. Material Examined. Northeastern Pacific, Puget Sound , East Anderson Island, Sta. 44, Rep. 1, 0 7 April 1992, 47.16133°N, 122.67358°W, 20 m, 3 specimens (MSMP AN 295); Shoreline Elliott Bay, Sta. 181, Rep. 1, 18 June 1998, 47.61504°N, 122.36230°W, 36.7 m, 2 specimens (MSMP AN 1084); Magnolia Bluff, Sta. 32, Rep. 5, 25 March 1990, 47.63192°N, 122.40850°W, 21 m, 1 specimen (MSMP AN 2345). Description. A large species, complete specimen from Sta. 181, 40 mm long, 1.8 mm wide across thorax with about 300 setigerous segments; all segments narrow, crowded. Thoracic region with about 50 setigers, gradually transitioning into abdominal segments; these also narrow and crowded (Fig. 16 A–B). Noto- and neuropodia closely spaced, located in raised mounds extending as shoulders along body (Fig. 16 A); in cross section, thoracic region high, rounded dorsally well above parapodia, flattened, slightly concave ventrally with distinct ventral groove; middle and posterior segments with deep ventral groove with parapodial shoulders shifting ventrally, forming sides of groove (Fig. 16 C). Far posterior end gradually narrowing with pygidium consisting of a simple ventral lobe below anal opening (Fig. 16 C). Color in alcohol light tan to brown; posterior thoracic segments sometimes appearing creamy in color but not glandular as with some species of Aphelochaeta . Prostomium triangular to conical, pointed on anterior margin (Fig. 16 A–B); eyes lacking; nuchal organs curved grooves on posterior border; prostomium and peristomium together slightly longer than wide (Fig. 16 A–B); peristomium typically with three annular rings (Fig. 16 A–B); dorsal tentacles medial, arising at level of setiger 1 on posterior medial extension of peristomium. First pair of branchiae arising lateral to dorsal tentacles on anterior margin of setiger 1; second branchiae on posterior margin of setiger 1 dorsal to notosetae; subsequent branchiae in same position on setiger 2 and following setigers. Parapodia well developed anteriorly, produced into expanded tori bearing dense fascicles of 25 or more long, smooth, silky capillary setae (Fig. 16 B); middle segments similar, with long, smooth notosetae and shorter, broad, distinctly serrated or denticulated neurosetae (Fig. 16 D); posterior setae short, reduced to 5–8 per fascicle; denticulated notosetae absent; serrated neurosetae not apparent on last few setigers; denticulated neurosetae with numerous tightly spaced denticles along one edge; denticles apparent only at 1000x (Fig. 16 D). Methyl Green stain. Stain not retained anywhere on the body after differentiation. Remarks. Kirkegaardia serratiseta is an unusual species; with its large robust size, morphology of the presetigerous region, and numerous crowded segments with dense fascicles of long, silky capillaries, it superficially resembles species of Aphelochaeta rather than Kirkegaardia . Indeed, the only character allying the species to Kirkegaardia is the denticulated or serrated neurosetae. The record of M. cf. serratiseta by Diaz-Diaz et al. (2014) from Venezuela is of a different species because the prostomium is longer than wide and lacks any annulations (Diaz-Diaz et al. 2014: Fig. 2 f) despite the text stating there are three; in addition, the pygidium is of a different morphology. Biology. Kirkegaardia serratiseta occurs in sediments consisting mostly of sand and lesser amounts of silt and clay (Banse & Hobson 1968). Blake (1996) reported one specimen with eggs measuring 110 x 150 µm. Distribution.
