Based on type specimens, we reassess the larger benthic foraminifera Miogypsinella borodinensis, type of the genus, and Miogypsinoides lateralis. We show that two Miogypsinella species were widespread across the Indo-Pacific in the Chattian–Aquitanian, while another lived in the eastern Pacific. The latest Aquitanian Indonesian Seaway restriction and widespread deeper-water deposition on SE Asia carbonate platforms likely caused the extinction of the studied Indo-Pacific taxa.
