The Neogene Alibonca, Kuseyin, Parcikan, Boyaca formations and the Mamaar volcanic unit occur at Arguvan (Malatya, Eastern Anatolia). Nine species of ostracods were identified and assigned to four genera in samples collected from the Kuseyin and Parcikan formations. The faunal content in these units was characterized by few ostracod species and abundant individuals. Most samples contained fewer than nine species. Ilyocypris bradyi, Ilyocypris gibba, Candona parallela pannonica and Heterocypris salina are described in the Kuseyin Formation. Cyprideis pannonica, Cyprideis anatolica, Cyprideis torosa, Ilyocypris gibba, Candona angulata, Candona neglecta, Candona parallela pannonica and Heterocypris salina are described in Parcikan Formation. Cyprideis, which has ecophenotypic ornamentations (smooth, punctuated, reticulated or nodes), is the dominant genus in the Parcikan Formation.
