Diagnosis.
Body elongated, not divided into distinct regions; ventral groove and two lateral grooves from chaetiger 2 to posterior end. Segments annulated. Prostomium conical, sometimes with terminal palpode; subdermal eyespots; a pair of large, eversible nuchal organs. Single and cirriform branchiae from chaetiger 2. Sometimes one or several posterior segments abranchiate. Segmental lateral eyes present between parapodia. Parapodia with prechaetal lobe, ventral lobe and sometimes a dorsal cirrus. Noto- and neuropodial lappets absent. Interramal ciliated organ present sometimes. Noto- and neuropodial small fascicles of simple capillary chaetae. Pygidium with conspicuous expansion—anal (pygidial) tube (funnel)—of variable shape, usually bearing internally attached midventral cirrus, marginal papillae and sometimes a basal pair of papillae.
Diagnosis modified from
Uebelacker (1984)
and
Blake (2000)
by introducing a more detailed description of parapodial and anal tube characters, and confirming the presence of a parapodial ciliated sensorial organ in the parapodial prechaetal lobe.
