Description. A moderate-sized species, holotype and larger paratypes 12–13 mm long, 0.9–1.0 mm wide across anterior fourth of body, with 85–90 setigers. Color in alcohol light tan to brown, lacking any distinctive body pigment. Body with narrow crowded segments for two-thirds of body, without any prominent swelling or anterior enlargement (Fig. 14 C–D); dorsal groove absent or weakly developed anteriorly (Fig. 13 A), emphasized in far posterior segments by overlap of dorsal cinctures (Figs. 13 A, 14F); venter flattened, with deep prominent midventral groove continuing along entire body through cinctured posterior segments (Fig. 14 B, D). Prostomium broadly triangular, narrowing anteriorly to bluntly rounded tip (Figs. 13 A, 14A–B); eyes absent; nuchal organ at posterior lateral margin, consisting of narrow slit, sometimes weakly pigmented (Fig. 13 B). Peristomium with two large rings, both overlain dorsally by an inflated ridge or crest extending posteriorly to level of setiger 1; these peristomial rings followed by narrow achaetous segment having a similar shape as setiger 1. Dorsal tentacles arising from groove at posterior end of second large peristomial ring (Figs. 13 A–B, 14A); first pair of branchiae arising posterior to tentacles on posterior margin of achaetous segment; achaetous segment approximately same size as subsequent setigers, sometimes with a lateral furrow (Figs. 13 A–B, 14A); second pair of branchiae arising dorsal to notosetae on first setiger immediately posterior to achaetous segment 1 (Figs. 13 A, 14A); subsequent setigers with branchiae dorsal to notosetae; branchiae of anterior setigers thicker than those in middle segments.
