Species Hedbergella sigali Moullade 1966


Alternative name:
Hedbergella (Hedbergella) sigali Moullade 1966
Discussion / Comments:
Caron (1985):
The species differs from the slightly larger H. delrioensis in having only 4 instead of 5-6 globular chambers forming the last whorl.
Pflaumann & Krasheninnikov (1977):
The last whorl is composed of four to four and one-half chambers with lobate periphery and narrow .umbilicus. Differs from other hedbergellas by its low number of chambers in the last whorl, from C. hoterivica by its low main aperture, and from Gubkinella by its low spira. On Plate 1, Figure 3, 4 are shown four-chambered forms of larger sizes, determined as H. aff. sigali with respect of their poor preservation.
