Boudagher-Fadel et al. (1997): Remarks: Loeblich and Tappan (1988, p. 704) considered Loeblichella Pessagno (1967) as a genus of uncertain status; the types being probably internal moulds and poorly preserved. Also, Longoria's specimens lack the sutural apertures on the spiral side originally said to occur on the type species, Praeglobotruncana hessi hessi. According to Longoria (1974), his L. convexa differs from L. moulladei only by having a less convex dorsal side. A close study of the type specimens of the two species (reproduced in Plate 8.4, Figs 1-6) shows that the degree of convexity of the dorsal side, in both species, is the same. We regard them as synonyms and, as first revising authors, select convexa has having priority. B. convexa has five very depressed chambers (h/L = approx.) in the last whorl. The umbilicus is narrow (u/uh = 0.25 approx.). The aperture is a narrow intraumbilical-extraumbilical slit. |
