摘　　要：本文描述了产自广西小董中二叠统板城组的一个放射虫新亚种Pseudoalbaillella globosa guiglobosa,该亚种与P.globosaIshiga et Imoto的区别在于具有较大的假胸部和较短的假腹部。除壳体大小外,P.globosa还具有多种形态的顶锥和假腹部,可能还有其它亚种存在。This article describes a new radiolarian subspecies, Pseudoalbaillella globosa guiglobosa subsp, nov. , obtained from the Middle Permian Bancheng Formation in Xiaodong, Guangxi, South China. This subspecies is characterized by a larger pseudothorax and a shorter pseudoabdomen than the previously-reported specimens of P. globosa Ishiga et Imoto. In addition to the shell sizes, P. globosa is varied in the apical cone and the pseudoabdomen, implying the presence of other subspecies.
