Distinguishing features: Unicyclic (or bicyclic?), small (or medium); bar complex, wide rim/small openings
Morphology: A long-ranging and rather poorly-defined taxon which, like Z. erectus, may include homeomorphs. The holotype was a small (3 µm) Jurassic form but the name has also been applied to larger forms (5-7 µm), especially in the Late Cretaceous. Likewise the name seems to have been applied to both unicyclic and bicyclic forms.
Size: Holotype length 2.9µm.
