Description Diagnosis: We reproduce in totality the diagnosis of Mamet in Armstrong & Mamet (1974): “Test free subglobular. Proloculum (sic: for proloculus) followed by biserial succession rapidly enlarging chambers, with initial biseriamminid coil followed by open helicoid coil. Valvular projections poorly developed. Wall calcareous, secreted, as dense tectum. Aperture simple, lobate, at base of apertural (sic for the pleonasm) face”.
Occurrence: (according to Vachard et al., 2006, p. 470) Early Namurian of England (Fewtrell et al., 1989). Late Viséan of Submoscovite Basin and Uzbekistan. ?Latest Venevsky to latest Serpukhovian of southern Urals. ?C1 vg-earliest Serpukhovian of Donets Basin (limestones B4, B10 and C1) to early Bashkirian (D72 limestone). Late Visean of southern Spain. Latest Visean-early Serpukhovian of USA. Earlylate Brigantian of central and eastern Morocco (the populations of the Idmarrach Formation are especially interesting; see Saïd, 2005; Karim, 2007; Cózar et al., 2008b). Latest Brigantian of eastern Taurus (Turkey). Serpukhovian of Kazakhstan. Earliest Serpukhovian of Tien-Shan (local FAD according to Orlov-Labovsky, 2005). ?Serpukhovian of Thailand (Chiang Dao area). Latest Brigantian of South China. Early Serpukhovianearliest late Serpukhovian of Tien-Shan. Early Serpukhovian of northwest China. Earliest Serpuhkhovian of northern England. ?Late Serpukhovian of Idaho (USA). ?Late Serpukhovian-early Bashkirian of Alaska and Hina Group of Japan. Early Serpukhovian of Montagne Noire (southern France). Late Serpukhovian of Pyrenees (southern France). In our studied material, “B.” bristolensis is MFZ8. The specimens are very rare from MFZ9 to MFZ13 and rare in MFZ14. The acme is situated in MFZ15-16. The LAD poorly because of the misinterpretations with true Globivalvulina.
