Dorsal cerata finger-shaped to fusiform, forming up to ten comb-shaped rows on dorsal side. Apices of cerata gradually pointed, with elongate cnidosac. Distinct notal edge remains mostly below cerata clusters. Digestive gland diverticulum fills significant volume of the cerata.

One species is highly divergent at 12.98%, and the other one is closer but still different (1.83%) from the Commander Islands specimens. The Commander Islands specimens are therefore recognised as a separate subspecies
