is unusual among bitentaculate cirratulids in having a multilobed pygidium and a unique grooved apical enlargement on the acicular spines. Although prominent and well-developed neuropodial acicular spines are present, notopodial spines are reduced to a pair of spinous capillaries. The absence of an equivalent number of notopodial spines and of distinct posterior cinctures of spines departs from the latest generic diagnosis of the genus. In this regard,
