Brachiopods from the Otar Member (upper Caradoc) of the Dulankara Formation, Kazakhstan, are revised. Twenty‐one species are represented of which the orthoid genus Bokotorthis and strophomenoid genus Karomena are new. New species are Phaceloorthis reconditaPlaesiomys fidelisAnoptambonites kovalevskii, Karomena squalidaDzhebaglina plicata. Three ecological associations are identified, the Altaethyrella‐Nalivkinia (Pronalivkinia) Association, the Ctenodonta‐Sowerbyella Association and the Dinorthis Association, all living in shallow‐water (BA2) environments. The fauna shows closest affinity with South China, but contains two genera only known elsewhere from Australia.
