巴尔干半岛的半岛丰富的Riskidoides动物群，其历史开始于Paratethys时代，尚未得到充分的研究。除其他外，它包括许多小腹足动物的分类群，具有中等高度的螺旋壳，阴茎左边缘有双叶，雌性生殖器官有一圈盘绕的输卵管和两个容器，其形态不允许确定。在这篇文章中，我们讨论了五个这样的群体。本文描述了采自罗马尼亚多布罗加省特奇尔格湖的古蛙Grossuanacodreanui（Grossu，1946）的壳、齿舌、软体部分的形态和生殖器官的解剖结构。在分子水平上（线粒体CO1和核糖体18 S两个基因的片段）与G. codreanui，保加利亚G. serbica（Radoman，1973），Belgrandiella haesitans（Westerlund，1881）来自洛罗斯河的春天，Orientalina delphica（Radoman，1973）来自德尔菲的春天Kastalia。5个居群均属于Grossuana属：G. codreanui，G. serbica，G. vurliana（Radoman，1966），G. dephica（Radoman，1973）。我们应用了12个形态特征的Grossuana和其他17个riskididean属（主要是Hydrobiidae s。stricto）推断出该属在Hydrobiidae s中的位置。最靠近Orientalina。所有的分子数据证实，Grossuana是属于Hydrobiidae，Horatiinae的一个独特的属，其最近的亲戚是Belgrandia，Orientalina和Horatia。
The rich rissooidean fauna of Balkan Peninsula, the history of which began at the time of Paratethys, is not sufficiently studied yet. It includes, among others, many taxa of minute gastropods with a moderately high-spired shell, a penis with a double lobe on its left edge and female reproductive organs with a loop of coiled oviduct and two receptacles, the morphology of which does not allow for a certain determination. In the article we deal with five such populations. We describe the shell, radula, soft part morphology and anatomy of the reproductive organs of Grossuana codreanui (Grossu, 1946) from its type locality at the Techirghiol Lake, Dobrogea, Romania. The species is compared molecularly (fragments of two genes: mitochondrial CO1 and ribosomal 18 S) with G. codreanui from Bulgaria, G. serbica (Radoman, 1973) from its type locality, Belgrandiella haesitans (Westerlund, 1881) from the spring of the Louros River, and Orientalina delphica (Radoman, 1973) from the spring Kastalia at Delphi. All the five populations were found to belong to the genus Grossuana: G. codreanui, G. serbica, G. vurliana (Radoman, 1966), and G. dephica (Radoman, 1973), respectively. We applied 12 morphological characters of Grossuana and 17 other rissooidean genera (mostly of the Hydrobiidae s. stricto) to infer phylogeny, which has shown the position of the genus within the Hydrobiidae s. stricto, most close to Orientalina. All the molecular data confirm that Grossuana is a distinct genus belonging to the Hydrobiidae, Horatiinae, whose closest relatives are Belgrandia, Orientalina and Horatia.
