Abstract: Genus Azarinautilus Korn & Ghaderi, 2025 Type species Azarinautilus nahidae Korn & Ghaderi, 2025; original designation. Diagnosis Genus of the family Ocunautilidae fam. nov. with a rather small, subinvolute or subevolute conch; whorl profile lyriform, venter moderately to deeply concave and bordered by raised keels, umbilical margin broadly rounded or subangular. Sculpture with conical nodes or shallow ribs in the midflank area. Suture line with narrow, rounded external lobe and broadly rounded lateral lobe (from Korn & Ghaderi 2025). Included species NW Iran (Korn & Ghaderi 2025): Azarinautilus nahidae Korn & Ghaderi 2025, Wuchiapingian. Central Iran (this paper): Azarinautilus phorminx sp. nov., Changhsingian. Remarks Azarinautilus has an isolated position within the family Domatoceratidae because of its conch shape and sculpture. A comparably distinctly concave venter has apparently not been described from any other genus of the family; however, species of Fididomatoceras show a flat or slightly concave venter bordered laterally by low ridges.
