Current identification/main database link: Asterohedbergella Hamaoui 1965
Original Description
Family Globotruncanidae; subfamily Rotaliporinae. Cenomanian. Monotypic.
Extra details from original publication
Hedbergella (Asterohedbergella) Hamaoui differs from its probable ancestor Hedbergella (Hedbergella) Bronnimann and Brown, 1958 by its peripheral radially elongated, pointed to tubulospinate chambers. From Hedbergella (Clavihedbergella) Banner and Blow, 1959, this new subgenus differs by the shape of its radially elongated chambers which are pointed to tubulospinate. but neither simply protruding, nor terminally inflated and club-shaped (clavate). H. (Asterohedbergella) resembles Hastigerinoides Bronnimann, 1951, but is trochospiral throughout, not biumbilicate. and has an aperture which is never equatorial. H. (Asterohedbergella) resembles furthermore Schackoina Thalmann. I932, but is trochospiral throughout and its aperture does not become equatorial. H (Asterohedbergella) is distinguished from Rugoglobigerina (Plummerita) Bronnimann, 1951 by the absence of meridional rugosities (costellae) and of large umbilical flaps or tegilla with intralaminal accessory apertures.
