The Rugose linoproductoid 'Permundaria' Nakamura, Kato, and Choi, 1970 was stated to be a "poorly understood genus" in the new Brachiopoda Treatise (Brunton et al., 2000, p. 563). It is an uncommon genus confineD to the Middle-early late Permian Thethys Sea, and reports of it have usually been based on only a small number of specimens. In this study, some 30 samples of 'Permundaria' were recovered from the Bera South beds (Wordian, Middle Permian) of the Bera Formation, Pahang, Penisular Malaysia. The material represents a new species of the genus, which is here described. Its new morphological information enables taxonomic revision of this often misunderstood genus, and helps to clarify some confusion among related, or superficially similar, linoproductoid genera.
