对许多地理上广泛分离的地层剖面的研究，涵盖了晚中新世到近代的间隔，允许追溯可归属于Pulleniatina属的物种的起源和进化。Pulleniatina primalis，n. sp.，P. p.亚种，P. acetyloculataacetyloculata和P. acetyloculatafinalis，n.亚种，在生物地层学中是有用的。Pulleniatina pullenabilis被认为是与P. primalis形成一个独立的进化系，并且在印度-太平洋省的上新世有一个短的范围。Pulleniatina似乎起源于Globorotalia（Turborotalia）acostaensis Blow，1959，而这个形式的正模标本被重新图解。Globigerina inflata d 'Orbigny，1839，被证明与Pulleniatina acidiloculata（s. l.），现提出前一分类群的新模式。链螺旋体卷曲的意义进行了检查。新的单型属Rotaliatinopsis建议容纳”？Pulleniatina semi-involuta”Germeraad，1946，与球孢纲（Globigerinacea）无关。|| 摘要编辑：作者
Studies of many geographically widely separated stratigraphical sections covering the Late Miocene to Recent interval have allowed the origin and evolution of species referable to the genus Pulleniatina to be traced. The evolutionary sequence Pulleniatina primalis, n. sp., P. obliquiloculata praecursor, n. subsp., P. obliquiloculata obliquiloculata and P. obliquiloculata finalis, n. subsp., is shown to be useful in biostratigraphy. Pulleniatina spectabilis is recognised as forming a separate evolutionary line from P. primalis and as having a short range in the Pliocene of the Indo-Pacific province. Pulleniatina seems to originate from Globorotalia (Turborotalia) acostaensis Blow, 1959, and the holotype of this form is re-illustrated. Globigerina inflata d'Orbigny, 1839, is shown to be unrelated to Pulleniatina obliquiloculata (s. l.), and a neotype for the former taxon is now proposed. The meaning of streptospiral coiling is examined. The new monotypic genus Rotaliatinopsis is proposed to accommodate"? Pulleniatina semi-involuta" Germeraad, 1946, which is unrelated to the Globigerinacea. || ABSTRACT AUTHORS: Authors
