Distribution. East China Sea, Japan, and Sakhalin, 50–1115 m.

Remarks. This species is closely related to Henricia arcystata Fisher , but differs in each adambulacral plate bearing more numerous subadambulacral spines (on the plate surface) and a single furrow spine, not three furrow spines in a vertical series. Our specimens do not possess a short series of the secondary ventrolateral plate at the arm base. In addition, the present specimen extends the depth of the species to 1115 meters.
