Citation: Watznaueria fossacincta (Black, 1971) Bown in Bown & Cooper, 1989
Rank: Species
Basionym: Ellipsagelosphaera fossacincta Black, 1971

Notes & discussion: Intergrades with W. barnesiae, which has a closed central area but the morphotypes have different distributions with the fossacincta type being more common in the Jurassic and the barnesiae type in the Cretaceous.
