Anarthruropsis langi Kudinova-Pasternak, 1976: 121 –123, fig 3.
Remarks. Although not recorded in the recent Japanese surveys, this species has been recorded from the northern part of the Kurile-Kamchatka Trench, at hadal depths, 7795–8015 metres. The complex and varied spiniform setae on pereopods 3–6 distinguish it from A. longa, as well as its shorter pereonites 4–5.
