Diagnosis.

Eyes absent. Paragnath counts: Area I = 2; II = 14-16; III = 0-3 (unclear, possibly damaged during dissection); IV = 9; V absent; VI = 6; VII-VIII = 30-40. Dorsal notopodial ligule markedly broader and elongate on posterior chaetigers. Prechaetal notopodial lobe absent. Dorsal cirrus length ~ twice acicular notopodial ligule at chaetiger 10-20. Dorsal cirrus on posterior chaetigers terminally attached to dorsal notopodial ligule. Neuropodial prechaetal and postchaetal lobes absent. Ventral neuropodial ligule ~ as long as acicular neuropodial ligule. Notopodial homogomph spinigers present. Notopodial homogomph falcigers present. Notopodial homogomph falciger blades very long. Notopodial homogomph falcigers multidentate, with two or more small lateral teeth, first and subsequent lateral teeth much smaller than terminal tooth. Neurochaetae: dorsal fascicle heterogomph spinigers absent. Neuropodial dorsal fascicle homogomph spinigers and heterogomph falcigers. Neurochaetae, ventral fascicle: heterogomph spinigers and heterogomph falcigers.
