Abstract
Partial revision of the Permian–Triassic freshwater ostracod genus Gerdalia Belousova, 1961 is performed. The genus is shown to be a collective group. The holotype of the type species G. polenovi Belousova, 1961 is shown to originate from the Late Vyatkian of well 1 near the town of Lyubim, Yaroslavl Region rather than from the Early Urzhumian of the Belebey section (Bashkortostan), as erroneously indicated in the original description. Species that belong to the genus Gerdalia can be divided into six groups according to a combination of morphological features.
