Diagnosis After Blake (2021). Subfamily and genus diagnosis. Body elongate, threadlike, up to 10 mm long with 45–65 setigerous segments; body segments cylindrical in cross section; setigerous segments with 2–3 intersegmental annulations in anterior setigers, up to 7–8 in middle segments, decreasing posteriorly. Prostomium conical, tapering to narrow rounded tip; nuchal organs paired slits on posterior lateral margins. Peristomium typically with 2–3 asetigerous rings, with dorsal surfaces smooth, entire; ventrally forming anterior and posterior lips of mouth. Thoracic and abdominal regions only vaguely identified by shorter, wider segments anteriorly and longer, narrower segments posteriorly. Paired branchiae present dorsally in posterior segments or entirely absent. All parapodia biramous, composed of low mounds bearing noto and neurosetae; setae serrated or weakly camerated capillaries and bidentate hooks with geniculate shafts in both rami; furcate setae present or absent in notopodia. Pygidium with 0, 2, or 4 anal cirri. Sexually dimorphic morphology. In mature males segments 13–14 (15) with elevated cup-like or slit-like dorsal fold. Mature females of almost all species with more-or- less papillated glandular epidermis in anterior segments. Extension and shape of papillation on females species-specific, but also depending on stage of maturity. Egg region (mostly segments 12–13) of mature females slightly swollen due to formation of 2–3 large eggs. [details]
