Species Lilliputianella maslakovae Longoria 1974


Discussion / Comments:
Banner & Desai (1988):
L. maslakovae has slowly enlarging chambers (about seven in the last whorl) which become ovoid and higher than broad in the latter half of the last whorl. The trochospire is very low but the spiral side is flat (as depicted by Longoria (1974) for his holotype), not necessarily concave as in the original, type description. The umbilicus occupies about 1/5 of the test diameter and the low aperture extends from the umbilicus to the periphery; because of the low trochospirality, the peripheral part of the penultimate aperture may be incompletely closed by the final chamber and may remain as a small sutural opening on the spiral side. Such sporadic openings in the spiral suture led Longoria (1974, p. 72-74) incorrectly to refer some species of Blefusciana (but not Lilliputianella) to Loeblichella Pessagno, which is a muricate, macroperforate. Late Cretaceous genus descended from Hedbergella. We consider these sporadic, relict openings in the spiral suture not to be valid as a generic criterion, in Lilliputianella or Blefuscuiana or even in Hedbergella.
