Diagnosis. Prostomium anteriorly rounded; with frontal lips. Antennae and palps with ceratophores with 3–10 rings, rarely with small lateral projections; styles usually short to moderately long, median antenna shorter or equal to lateral antennae. Nuchal grooves slightly curved with wide mid-dorsal separation. Peristomial cirri present or absent. Anterior three (rarely four to five) pairs of parapodia modified but not enlarged. Ventral cirri subulate to digitiform on anterior two to eight chaetigers, ventral glandular pads with cuticular pore patterns; dorsal cirri moderately long. Branchiae with single or pectinate filaments, present only through median chaetigers or absent. Hooks of modified parapodia pseudocompound with moderately long to long pointed hoods; dorsal limbate chaetae from chaetiger 1, ventral limbate chaetae replacing pseudocompound hooks from chaetiger 4 or later until replaced by bidentate hooded subacicular hooks from chaetiger 9–28; pectinate chaetae flat with slightly oblique distal margin or slightly scoop-shaped with rolled lateral margins from chaetiger 9 or later. Tubes round in transverse section, with inner parchment-like layer covered with extraneous particles.
