Family ENDOTHYRANOPSIDAE Reitlinger, 1958 Bradyinoids small to medium in size having in common the test planispiral involute generally nautiloid. Moderate number of whorls and chambers. Septa truncated at the base. Supplementary deposits absent or represented by a terminal hook. Wall dark simple, to calcareously agglutinated. A pseudokeriotheca exists in the most advanced Endothyranopsis . Aperture terminal, simple, basal. Early Ivorian (MFZ 5)-Changhsingian.

Subfamily ENDOTHYRANOPSINAE Reitlinger, 1958 Bradyinoids small to medium in size, planispiral involute and generally nautiloid. Moderate number of whorls and chambers. Septa truncated at the base. Supplementary deposits absent or represented by a terminal hook and some pseudochomata. Wall dark simple, relatively thick and generally calcareously agglutinated. A fine pseudokeriotheca exists in the most advanced Endothyranopsis . Wall terminal, simple, basal.

Remark: This subfamily has been partially restudied by Vachard & Cózar in Liu et al. (2023): Bibradya Strank, 1983 was transferred in the family Janischewskinidae with its subjective junior synonym Groessensella Strank in Somerville & Strank, 1984. Rectocribranopsis Kobayashi & Vachard, 2022 is a recent addition published after Vachard & Le Coze (2022). Spinothyra is transferred herein in the Endothyridae . Its microgranular wall structure makes it closer to this latter family.

Composition: Cribranopsis Conil & Longerstaey, 1980 ; Endothyranopsis Cummings, 1955 ; Granuliferella Zeller, 1957 ; Latiendothyranopsis Lipina, 1977 ; Plectogyranopsis Vachard, 1977 ; Rectocribranopsis Kobayashi & Vachard, 2022 .
