Globoreticulina Rahaghi (1978) 属模式种的定义，1978 年，G. iranica Rahaghi (1978) 进行了修订，并讨论了其年龄与 17 个大型有孔虫相关类群的关系，这些类群均来自有限的浅水环境。这些类群代表了螺旋线习性的瓷器类群，包括Rhabdorites malatyaensis、archaiasines（Archaias operculiniformis 和 A. diyarbakirensis）、凝集圆锥体（Coskinolina 和 Dictyoconus）和一些轮虫类（Medocia 等）。这些类群在必要时进行了修订，并讨论了它们的生物地层范围。除了建立 Alveolinidae 的新亚科 Malatyninae 之外，还引入了以下新的 Linnaean 名称以符合修订内容：Austrotrillina eocaenica n. sp., Neotaberina neaniconica n.将军名词sp., Neorhipidioninaspiralis n.将军名词sp.，Penarchias n.将军和 Rotaliconus persicus n.将军名词sp。 Praerhapydionina huberi Henson 种被转移到 Haymanella Sirel 属，而 Praearchaias Sirel 属被抑制。根据当地现有资料，Globoreticulina iranica 类型层的年龄被解释为 SBZ 18（晚巴顿世），但不能肯定地排除其地层位置实际上是 SBZ 17 或 SBZ 16 层的可能性。
The definition of the type species of the genus Globoreticulina Rahaghi, 1978, G. iranica Rahaghi, 1978, is emended and its age discussed in relation to those of 17 associated taxa of larger foraminifera, all from restricted shallow environments. These taxa represent porcelaneous groups of spiroline habit including Rhabdorites malatyaensis, archaiasines (Archaias operculiniformis and A. diyarbakirensis), agglutinated conicals (Coskinolina and Dictyoconus) and some rotaliids (Medocia and others). These taxa were revised where necessary and their biostratigraphic ranges discussed. In addition to the establishment of a new subfamily of the Alveolinidae, the Malatyninae, the following new Linnaean names are introduced in order to conform with the revisions: Austrotrillina eocaenica n. sp., Neotaberina neaniconica n. gen. n. sp., Neorhipidionina spiralis n. gen. n. sp., Penarchaias n. gen. and Rotaliconus persicus n. gen. n. sp. The species Praerhapydionina huberi Henson is transferred to the genus Haymanella Sirel and the genus Praearchaias Sirel is suppressed. The age of the type level of Globoreticulina iranica is interpreted to be SBZ 18 (Late Bartonian) according to the available local data but the possibility that its stratigraphic position is actually level SBZ 17 or SBZ 16 can not be excluded with certainty.
