Nomenclatural junior synonym: Aiora Davey (name illegitimate), which has the same type.

Type species: originally as Aiora fenestrata, Cookson and Eisenack, 1960a (pl.2, fig.17)] ; Balteocysta perforata, Wilson and Clowes, 1980

Original description: [Stover and Evitt, 1978]:

Synopsis:
Cysts proximate; autocyst subspherical with five or six paracingular intratabular processes; processes branched repeatedly and interconnected distally by equatorial trabecular ectophragm, archeopyle type unknown.

Description:
- Shape: Body subspherical; overall outline circular, or nearly so.
- Wall relationships: Autophragm and equatorial trabecular ectophragm widely separated between processes.
- Wall features: No parasutural features. Five or six paracingular intratabular processes, which are solid or hollow and branched repeatedly, with distal trabeculae; latter connected to form perforate equatorial ectophragmal band, cyst features smooth.
- Paratabulation: Indicated only by paracingular processes.
- Archeopyle: Type not known.
- Paracingulum: Indicated by five or six intratabular processes.
- Parasulcus: Not indicated.
- Size: Large.

Affinities:
Balteocysta differs from Adnatosphaeridium in having paracingular intratabular processes only. On Adnatosphaeridium the processes are more numerous and the trabecular ectophragm forms a loose mesh, which more or less surrounds the entire cyst rather than being an equatorial feature, as in Balteocysta.
