Rissoa (Alvania) akibai Yokoyama, 1926: 275 View in CoL , pl. 34, fig. 3 (see Hasegawa [2014] for more detailed synonymy).
Material examined. SoJaBio A 2-10, MIBM 39336 ( Fig. 2A View FIG ); SoJaBio B 6-7, MIBM 14492; SoJaBio B 7-7, MIBM 39342 [depth range: 455–1011 m].
Additional material examined (cited from Hasegawa, 2014). ZIN, non-registered, off Primorsky Krai, 44°48.5’N, 136°46.0’E, 373–494 m (voucher specimen of Punctulum sp. fide Golikov et al., 2001: 158) GoogleMaps .
Distribution. Off Primorsky Krai coast on the northern slope, and from Musashi Bank to off Shimane Prefecture on the southeastern slope in the Sea of Japan, within the depth range of 220–1011 m.
Remarks. This species was originally described based on fossils from the Pliocene Sawane Formation on Sado Island in the Sea of Japan, and is characterized by the peculiar pockmarked protoconch sculpture [ Hasegawa, 2014: fig. 37D]. Its previously known vertical distribution range was 220–635 m, and that is significantly extended to 1011 m in the present study.
