Description. A large species, two complete specimens; holotype largest, 25 mm long, 2.5 mm wide for 106 setigers; paratype 18 mm long, 1 mm wide for 82 setigers. Color in alcohol light tan to brown, lacking any distinctive body pigment. Body long, arched dorsally, with shallow, narrow, mid-dorsal groove along entire length of body (Figs. 11 A, 12 A), most prominent in anterior setigers, but reemphasized in far posterior segments by overlap of setae and membranes of dorsal cinctures; venter flattened, with deep prominent mid-ventral groove (Fig. 12 B) continuing along entire body through cinctured posterior segments (Fig. 11 F). Prostomium long, narrow, pointed on anterior end (Figs. 11 A–B, 12 B, D); eyes absent; nuchal organs elongated slits on posterior margin of prostomium (Fig. 11 B); peristomium with large anterior inflated buccal region followed by two narrow annulations, second annulation interpreted as an achaetous segment bearing a pair of dorsal tentacles and a pair of branchiae positioned laterally (Fig. 11 A–B). Subsequent setigers with branchiae dorsal to notosetae (Figs. 11 A–B, 12 D); anterior branchiae thicker than those of middle segments. Setiger 1 of approximately same size as preceding achaetous segment and following segments; podial lobes reduced to inconspicuous ridges in anterior setigers, becoming inflated and conspicuous in middle setigers, greatly enlarged with elevated ridges in posterior setigers on deeply cinctured segments bearing conspicuous armature (Fig. 12 A–C); posterior segments separated by deeply cut intersegmental furrows and with highly elevated membranous podial lobes from which spines and capillaries ...
