Description Test free, biserially coiled to biseriate, with a few whorls and a few chambers increasing rapidly in height. An oral valvula near the aperture. Supplementary deposits absent or very rare. Supplementary chamberlets occasionally present. Wall unilayered dark microgranular or granular with calcareous agglutinate, or bilayered with an inner pseudofibrous layer. Aperture simple basal.
Range and distribution: Latest Tournaisian (MFZ8)-latest Permian (Changhsingian); rarely cosmopolitan, common in the Tethyan and Uralian oceans. Earliest Triassic forms have been mentioned in South China (Song et al. 2007).

Taxonomic remark J. Pignatti (2022) pers. comm. kindly brought to our attention that according to the principle of coordination of the ICZN (1999), Biseriamminoidea Chernysheva, 1941 has priority in respect to Globivalvulinoidea Reitlinger, 1950.
As the genus Biseriammina and in consequence the exact definition of Biseriamminidae remains very problematical and disputable, and because, in contrast, Globivalvulinidae is currently well defined, we propose to denominate the Palaeozoic foraminifers, with an almost planispirally to partly trochospirally coiled, biseriate architecture as Globivalvulinoidea, instead of Biseriamminoidea. The application of the article 35.5. of the ICZN is under discussion since both Globivalvulinoidea and Biseriamminoidea are currently in usage. [details]
