Abstract
The results of the revision of Crassatella (Bathytormus) species from Middle Eocene deposits exposed by the quarry of the Ingulets Mining and Processing Plant and Vizirka-1 quarry (town of Krivoi Rog) are presented. The genus Bathytormus has been reclassified as a subgenus. Forms with ridge-like ribs in the umbonal region were differentiated from the species previously described as Bathytormus cipitis cipitis (Berezovsky, 1998) and described as a new species, Crassatella (Bathytormus) ignava sp. nov. The name C. (B.) cipita is retained for valves in which the upper part is covered with spaced lamellar ribs. C. (B.) cipita and its nominotypical subspecies are redescribed due to changes in their composition and diagnostic features.

摘要
介绍了 Ingulets 采矿和加工厂的采石场和 Vizirka-1 采石场（Krivoi Rog 镇）暴露的中始新世矿床中的Crassatella (Bathytormus)物种的修订结果。Bathytormus属已被重新分类为亚属。在脐带区域具有脊状肋骨的形式与以前描述为Bathytormus cipitis cipitis (Berezovsky, 1998) 的物种区分开来，并被描述为新物种Crassatella (Bathytormus) ignava sp。十一月 名称C. ( B. ) cipita保留用于上部覆盖有间隔层状肋的瓣膜。C。( B. ) cipita及其命名型亚种由于其组成和诊断特征的变化而被重新描述。
