We describe a new species of the Ariantinae genus Paradrobacia from the Middle Miocene (Langhian) of Bosnia and Herzegovina. The genus was represented so far only by three species from the Middle Miocene of Austria, the Late Miocene of Greece, and the Pliocene of Germany. Based on the conchological features of all available species, the genus Paradrobacia is revised and its stratigraphic and geographic ranges are evaluated. All species were found in lignites or lignite-bearing marls, which is why the genus is interpreted as an indicator of moist woodland environments. Related Miocene taxa and their systematic status are briefly discussed. Paradrobacia hrvatovici Harzhauser, Mandic and Neubauer n. sp. is introduced as a new species.

来自波斯尼亚和黑塞哥维那中新世的一种新的Helicidae（Gastropoda），其副寄生菌属（Paradidrobacia）

我们描述了来自波斯尼亚和黑塞哥维那中新世中期（Langhian）的Ariantinae属副杆菌的一个新物种。到目前为止，该属仅由奥地利中中新世，希腊晚期中新世和德国上新世三个物种代表。根据所有可用物种的贝壳菌学特征，对副寄生菌属进行了修订，并对其地层和地理范围进行了评估。所有物种均在褐煤或含褐煤的泥灰岩中发现，这就是为什么该属被解释为潮湿林地环境的指示。简要讨论了相关的中新世分类群及其系统地位。副寄生菌hrvatovici Harzhauser，Mandic和Neubauer n。sp。被引入为新物种。
