Three productidine brachiopods of Haydenella, Paraplicatifera, and Compressoproductus are recovered from the Tak Fa Formation (Wordian, Middle Permian) of the upper Saraburi Limestone Group exposed at Khao Wong of central Thailand (the western margin of the Indochina Terrane). The latter two genera are new to the Permian of Thailand, and the new species Paraplicatifera thaica is proposed herewith. Some taxonomic and nomenclatural problems in relation to the three genera are discussed. The assemblage suggests endemism for a Middle Permian marine faunule of the Indochina Terrane.
