Among Permian smaller foraminifers, the genus Dagmarita is one of the most studied due to its worldwide distribution. The detailed study of the Zal (NW Iran) and Abadeh (Central Iran) stratigraphic sections led to redescription of the genus Dagmarita and its taxonomic composition. In Dagmarita, a peculiar generic morphological character, represented by a secondary valvular projection, has been detected for the first time among globivalvulinid foraminifers. The phylogeny of Dagmarita, and in particular its ancestor Sengoerina, is discussed and the new species, D. ghorbanii n. sp. and D. zalensis n. sp., are introduced. Analogies and differences among all the species belonging to Dagmarita are highlighted and morphological features of the new taxa are shown in 3D reconstructions, useful for understanding differently oriented sections of the specimens in thin section.UUID: http://zoobank.org/3d8eb14c-7757-4cbd-877c-4bacd2d156da

修订后的二叠纪属 Dagmarita Reitlinger, 1965 (Dagmaritinae, Foraminifera) 及其系统发育关系

在二叠纪较小的有孔虫中,该属达格玛里塔由于其全球分布,是研究最多的一种。对 Zal(伊朗西北部)和 Abadeh(伊朗中部)地层剖面的详细研究导致对该属的重新描述达格玛里塔及其分类组成。在达格玛里塔,一种特殊的一般形态特征,以次级瓣膜投影为代表,首次在球形有孔虫中被发现。的系统发育达格玛里塔,尤其是它的祖先仙葛丽娜, 讨论和新物种,D.高尔巴尼n. sp。和D.扎尔西斯n. sp., 介绍。属于的所有物种之间的类比和差异达格玛里塔被突出显示,新分类群的形态特征在 3D 重建中显示,有助于理解薄切片中标本的不同方向的部分。UUID:http://zoobank.org/3d8eb14c-7757-4cbd-877c-4bacd2d156da
