Species Heterohelix navarroensis Loeblich 1951


Discussion / Comments:
Caron (1985):
This species commonly displays a planispiral initial stage. It differs from H. striata in the laterally more compressed and distinctly finer costate character of the test, which is also smaller in size and in which the chambers increase less rapidly.
