Remarks. Although, in a previous report ( Hanagata, 2004), the generic name Truncorotalia was applied to plano-convex globorotaliids, following the taxonomy of Loeblich and Tappan (1987), we here assign those species to Globorotalia . The phylogenetic relationship between two clades of plano-convex planktonic foraminiferal groups is still unclear; i.e., Globorotalia miozea conoidea conomiozea puncticulata inflata lineage and Globorotalia cibaoensis — juanai — crassula crassaformis tosaensis truncatulinoides lineage. These are assumed to have evolved independently from the same species, Globorotalia praescitula ( Norris et al., 1994) . A study of the Miocene differentiation from G. praescitula will resolve this problem.

Occurrence. Common in the upper part of the Yonahama Formation up to the Minebari Formation.
