The Upper Toarcian–Middle Aalenian sequences of the Gerecse Mts belong to the Mediterranean region of the Mediterran–Caucasian Realm, bigger part of the Ammonoidea collected here are represented by the suborders Phylloceratina and Lytoceratina. In this paper the species belonging to the subfamily Erycitinae Spath are documented as a contribution to the general taxonomic and biostratigraphic revision of the Ammonitina fauna. Considering the abundance and diversity of the subfamily, it was a dominant group in the Meneghinii to Opalinum Zones: during its acme Erycitinae formed 52% of the Ammonitina. Two genera, one subgenus and 15 species are represented by 117 determined specimens. Quantitative evaluation and problems of systematics are briefly discussed, genera and species are described. Introduction of two new taxa, Cagliceras enigmaticum n. sp. and Erycites gerecsensis n. sp. is designated.
