摘要
The genus Diodora Gray, 1821 is widely represented in the Middle Miocene of the Central Paratethys with specimens usually attributed to D. graeca (Linnaeus, 1758) or D. italica (Defrance, 1820), well-known recent species of the Atlantic / Mediterranean Basin. In samples from the Upper Badenian of Western Ukraine we found two clusters of Diodora specimens, showing a similarity with these species, but a review of shell diagnostic characters using a statistical approach has revealed their clear conchological separateness. The first species from Varovtsi and Horodok is attributed herein to D. nodosa (Eichwald, 1830), whereas the second species from Maksymivka is described as a new species, D. stalennuyi sp. nov. We consider that these molluscs inhabited the Polish-Ukrainian marginal part of the Late Badenian Basin. Detailed descriptions of the protoconch and teleoconch morphology of the taxa involved, including SEM images, are presented.

Diodora Gray属，1821年广泛代表于中央Paratethys的中中新世，其标本通常归属于D. graeca（Linnaeus，1758）或D. italica（Defrance，1820），着名的近期大西洋/地中海物种盆地。在来自乌克兰西部上巴登地区的样本中，我们发现了两个Diodora样本群，显示出与这些物种的相似性，但是使用统计方法对壳体诊断特征的回顾揭示了它们明显的心理学分离。 Varovtsi和Horodok的第一个物种在本文中归属于D. nodosa（Eichwald，1830），而来自Maksymivka的第二个物种被描述为新物种D. stalennuyi sp。十一月我们认为这些软体动物居住在巴登盆地晚期的波兰 - 乌克兰边缘部分。提供了所涉及的分类群的protoconch和远程混合形态的详细描述，包括SEM图像。
