Early Devonian brachiopods from Satun Province, southern Thailand

Twelve brachiopod taxa are described from the Early Devonian (probable earl y Emsian) Pa Samed Formation of southern Thailand, including the new genus and species Quasiprosserella samedensis (Ambocoeliidae?) and the new specie s Plectodonta forteyi, Caplinoplia thailandensis, and Clorinda wongwanichi. They are the first undoubted Devonian brachiopods from Thailand. They repr esent the deeper-water Benthic Assemblages BA4-5, and, although clearly ind icative of the Old World Realm, cannot be assigned to a particular biogeogr aphical region. A new undescribed fauna from the contemporary Zebingyi Form ation of Burma (Myanmar) is also noted.
