Prostomium anteriorly rounded, or with slight medial incision, prolonged posteriorly as a keel, lacking occipital tentacle. Peristomium only partly fused with, and therefore fairly distinct from, setiger 1. Branchiae numbering 4 pairs from setiger 2; each gill elongate, cylindrical, smooth, distinct from notopodial lamella. Neuropodial presetal lamellae connected in ventral crests on several anterior setigers from setiger 2. Notopodial postsetal lamellae connected in dorsal crests on several postbranchial setigers. Anterior setae all capillaries, multidentate hooded hooks in posterior neuropodia, notopodial hooks lacking. Pygidium with 2 short ventrolateral lobes and 1 longer dorsomedial cirrus, or 3 subequal lobes.
