摘要

对1956年俄罗斯(东欧台地和乌拉尔山脉)、土耳其和塔吉克斯坦(达瓦兹)石炭世(维西期，密西期子系统)至二叠纪(路帝期，Guadalupian Series)地层中Lasiodiscidae科的模式标本和新采集的有孔虫材料进行了形态学研究，从而对Howchinia属、Monotaxinoides属、Eolasiodiscus属、Turrispiroides属和Mesolasiodiscus属的物种组成进行了修正。描述了一个新属，Postmonotaxinoides。根据实验形态学的新数据，对过渡单轴单轴螨、扁轴单轴螨、细轴单轴螨、东bassiceolasiodiscus、galinae、Mesolasiodiscus tennus、nigrans、Postmonotaxinoides horridus、costiferus和大轴单轴螨进行了重新描述。对它们的分类进行了修正，并提出了新的系统发育重建。

Taxonomy and Evolution of Visean–Roadian (Late Mississippian–Guadalupian) Lasiodiscidae

The study of the test morphology of type specimens and newly collected foraminiferal material of the family Lasiodiscidae Reitlinger, 1956, from the Carboniferous (Visean Stage, Mississippian Subsystem) to Permian (Roadian Stage, Guadalupian Series) beds of Russia (East European Platform and Urals), Turkey, and Tajikistan (Darvaz) allowed a revision of the species composition of the genera Howchinia, Monotaxinoides, Eolasiodiscus, Turrispiroides, and Mesolasiodiscus. A new genus, Postmonotaxinoides, is described. The species Monotaxinoides transitorius, M. subplanus, M. gracilis, Eolasiodiscus donbassicus, E. galinae, Mesolasiodiscus tenuis, M. nigrans, Postmonotaxinoides horridus, P. costiferus, and P. grandis are redescribed based on new data of their test morphology. Their taxonomy is revised and new phylogenetic reconstructions for the species are proposed.
