Fig. 11 .

1952 Divaricella soyoae sp. nov.; Habe 1952: 160.

Material.— Five specimens from the Pleistocene of Buhoc Point NMNS PM 28142–28146 .

Dimensions (in mm).— NMNS PM 28142, L = 49.0, H = 47.0.

Remarks.— Divalucina soyoae is known from depth of 90 to 200 m in southern Japan ( Habe 1952; Dekker and Goud 1994); the genus has not been reported from seep sites before. Extant specimen of Divalucina soyoae are said to reach 47 mm in length( Dekker and Goud1994), which is only marginally smaller than those reported here. See Dekker and Goud (1994) and Amano (2019) for an extensive synonymy and a summary of fossil and recent occurrence of this species.

Stratigraphic and geographic range.—Late Pliocene: western Honshu, Japan. Pleistocene: eastern Honshu, Japan; Leyte, Philippines. Recent: southern Japan (Amano 2019).
