Diagnosis Prostomial anterior region entire, hemispherical, longitudinal groove present; prostomial posterior region as long as anterior region. Antennae present. Palpophores obtusely conical, with conspicuous transverse groove. Four eyes, lenticulate. Tentacular belt without ventrolateral projections. Four pairs of tentacular cirri. Jaws without denticles. Maxillary ring of proboscis cylindrical; oral ring of proboscis frustum-shaped. Proboscis with paragnaths only. Paragnaths conical, evenly spaced, present only on maxillary ring of proboscis. Paired oesophageal caeca absent. Segmental glandular patches absent. Notopodia well developed. Dorsal cirri attached medially to dorsal ligule in posterior chaetigers. Dorsal, median and ventral ligules present. Dorsal ligule with proximal region compressed. Notopodial prechaetal lobe present at least in anterior chaetigers, sometimes as acicular process. Neuropodial postchaetal lobe present, restricted to anterior chaetigers. Neuropodial superior lobe absent. Neuropodial inferior lobe present, throughout. Ventral cirri single. Notoaciculae absent in first 2 chaetigers. Notochaetae all homogomph spinigers, throughout. Upper neurochaetae with homogomph spinigers and lower neurochaetae with heterogomph spinigers, both restricted to anterior and middle chaetigers. Upper and lower neurochaetae with sesquigomph falcigers, present in middle and posterior chaetigers; without simple chaetae (fused falcigers). Blades of falcigers bowed.
