 note = {This paper describes five species of two productoid brachiopod genera, Spinomarginifera and Waagenoconcha, from the middle Permian (Wordian‒Capitanian) of the Kamiyasse‒Imo area, South Kitakami Belt, northeastern Japan. Cooccurrence of a tropical genus Spinomarginifera and an antitropical genus Waagenoconcha from the middle Permian of the South Kitakami Belt suggests that the South Kitakami region was located in the transitional zone between the Boreal and Tethyan realms, immediately east of North China (Sino-Korea) in the middle Permian.},
