The tabulate coral fauna from the Lower permian Ryozensan Limestone Formation, Mino Terrane in Shiga Prefecture consists of two auloporid species, i.e. the aulocystid Pseudoromingeria onishii sp. nov. and the sinoporid Sinopora ryozensanensis sp. nov. and is of Sakmarian age. This discovery of Pseudoromingeria onishii leads to the following emendations : a revised generic diagnosis is presented, and the stratigraphic range of the genus is extended from the Capitanian (Late Permian). The comparable forms with the present Ryozensan tabulate corals are known from the Akasaka Limestone, Gifu Prefecture, and Yunnan and Guizhou of South China. This paper represents the first reliable documentation of tabulate corals in the formation.
