Current identification/main database link: Pseudoglobigerinella bolivariana (Petters 1954)
Original Description
Description. - The test consists of 2½-3 whorls coiled in a planispiral, the initial 1-2 whorls are usually indistinct on the dorsal side due to which the test becomes almost bilateral. Consequently the form on the one hand surpasses diagnostic characters of the genus Globigerina d'Orbigny 1826, and on the other hand - it does not acquire complete characters of the genus Globanomalina Haque 1956. The last whorl consists of 4-5 slowly enlarging chambers. Dorsal and ventral intracameral sutures are deep, slightly curved. The umbilicus is broad, shallow. The aperture on the base of the last chamber is umbilical - extraumbilical, extending to the dorsal side; on the umbilical side it is provided with a distinct lip extending to the dorsal side. The wall is calcareous, perforate as in Globigerina bolivariana bolivariana Petters, 1954. The latter is connected with the subspecies described by intermediate forms.
