Forty-four species assignable to 32 genera of late Middle Permian (Capitanian) foraminifers are distinguished from Lepidolina limestone and microbial limestone of the uppermost part of the Taishaku Limestone, northeastern part of Hiroshima Prefecture, Japan. The microbial limestone contains Kahlerina taishakuensis sp. nov. enclosing problematic microfossils within their tests and is taxonomically less diversified than the Lepidolina limestone. Faunal composition of nonfusuline foraminifers is clarified in the Lepidolina Zone of the Akiyoshi Terrane for the first time. In addition to the new species, seven species are systematically described. They are Codonofusiella sp. cf. C. ashioensis Kobayashi, Chusenella otai (Nogami), Parafusulina sp., Lepidolina multiseptata (Deprat), Hemigordiopsis renzi Reichel, Baisalina ovata Han, and Partisania typica Sosnina. Taxonomic comments are given on Kahlerina and Hemigordiopsis.
