1949 Pseudoparella japonica Asano , p. 429, text-figs. 2—4.

2004 Pseudoparella japonica Asano — Scott, Takayanagi, Hasegawa, and Saito, p. 31, figs. 11.218, 11.219.

Remarks. We follow Takayanagi and Hasegawa

(1987) as far as the generic placement of this species is concerned. To the best of our knowledge,

there are no other reports except of the two mentioned above, both using the original type specimens at Tohoku University. Therefore, the range of variation is unknown. Ujiié et al. (1983) regarded this species to be synonymous with Epistominella pacifica (Cushman) , but that is a distinct species in a different genus.

Occurrence. A single specimen from the Minebari Formation.
