Abstract
Four species of Endothyranopsis are described and illustrated from the Pseudoendothyra spiroides zone of the Akiyoshi Limestone group, Akiyoshi plateau, Southwest Japan, and No. 17 horizon of the Onimaru formation, Kitakami massif, Northeast Japan. They are Endothyranopsi hirosei sp. nov., E. compressa (RAUSER-CHERNOUSSOVA and REITLINCER), E? sp. A, and E? sp. B. The foraminiferal assemblage in association with Endothyranopsis strongly suggests that the Pseudoendothyra spiroides zone of the Akiyoshi Limestone group is equivalent in age to the Onimaru formation (upper Viséan).
