Frigidoalvania tanseimaruae Hasegawa, 2014: 93–97 View in CoL , figs 4 G–K, 6 E–F, 10–13, 49B; table 5.

Material examined. SoJaBio B 6-6, MIBM 39347; SoJaBio B 6-7; SoJaBio B 7-7 [depth range: 470–1011 m]

Additional material examined (cited from Hasegawa, 2014). IORAN, non-registered, R/ V Vityaz st. 6649, Peter the Great Bay, 42°37.4’N, 134°19.2’E –42°37.8’N, 134°18.5’E, 1186– 1130 m GoogleMaps .

Distribution. Off Primorsky Krai coast on the northern slope, and from off southwestern Hokkaido to off Oki Island on the southeastern slope in the Sea of Japan, in a depth range of 369–1360 m with the clear mode around 1000 m (Figs 12–13). Probably endemic to the Sea of Japan.

Remarks. This species is superficially similar to some in the genus Punctulum through its rather thin periostracum and distinct teleoconch sculpture, but can be assigned to Frigidoalvania because of the close similarities in protoconch and radula characters to F. asura [ Hasegawa, 2014]. The intermediate state of characters of this species, however, may reinforce the closeness of the two nominal genera.
