We describe two species of reticularioid spiriferid brachiopod, Permophricodothyris grandis (Chao) and Permophricodothyris squamularioides (Huang), from the lower part of the Kamiyasse Formation (Wordian), Kamiyasse—Imo area, South Kitakami Belt, northeastern Japan. Permophricodothyris is known from the middle to upper Permian of the Tethyan region, especially from the upper Permian of South China. The two species from the Kamiyasse—Imo area are representative Tethyan elements of the middle Permian brachiopod fauna of the South Kitakami Belt.
