The Tournaisian productoid brachiopods, discovered from the base of the Luzhai Formation on the Jinzishan Section,Xing’an county, Guangxi of South China, including a new, a conformis and 6 indeterminate species, plus two forms described in open nomenclature, were described in this paper. These productoids are dominated by the forms of the families Productellidae and Productidae, and have only a few representatives of the echinoconchids and monticuliferids. All of the productoids belong to thin-shelled types dwelling in a low-energic environment and none has been recorded in other places of South China. The difference on the productoid brachiopod composition between the Jinzishan Section and other places in South China probably resulted from their different environmental conditions’ controlling . The productoids from Xing’an and the data recently discovered from the Nanbiancun of Guilin and Muhua of south Guizhou revealed that the Tournaisian brachiopod fauna in the slope margin to basinal facies of South China has an exceptionally high taxonomic diversity. It not only has abundant forms that characterizes the Tournaisian brachiopod faunas out of South China, but also contains many taxa that are new or previously considered to be stratigraphically restricted in horizons higher than the Tournaisian Stage. It is suggested that the slope margin to basinal facies of South China not only has a close biogeographical relationship with other places of the world, but also is one of the important origination and radiation centers of the brachiopods during the Tournaisian, from which many new genera and species are originated and then migrated to spread all over the world.
