SUMMARY
Prostomium with anterior margin indented. Longest tentacular cirri extend back to chaetiger 1–3. Maxillary ring of pharynx without paragnaths. Oral ring papillae present; solitary; 8–10 papillae present in total. Area V papillae present; 3 papillae; VI papillae absent; VII-VIII papillae present. Comprising a single row. 5–7 papillae. Oral ring paragnaths absent. In Ceratocephale spp, Area V and VI contain up to 3 papillae in total; these are here interpreted as all occurring in Area V, with VI=0,0. Transverse dorsal lamellae present; commencing chaetiger 10 (continuing to at least chaetiger 20). Prechaetal notopodial lobe present (exceeding dorsal notopodial ligule). Dorsal cirrus length about 2.5 times ventral notopodial ligule at chaetiger 10-20. Neuropodial postchaetal lobe present, at least on some anterior chaetigers. Ventral cirri paired. Commencing chaetiger 3. Notopodial homogomph spinigers present; sesquigomph spinigers absent. Notopodial homogomph falcigers absent. Neuropodial dorsal fascicle fused falcigers absent.
