Original description: [He Chengquan, 1991]: (translated by Suning Hou, 07-01-2019):

Description:
Cyst subspherical to spherical triangle; lack of apical, antapical horns and cingulum.
Tabulation is only obviously reflected by the edge of archeopyle.
Wall thickness medium 1.3 μm or so, stratification uncertain, surface with dense particles that are fine, clear and isolated.
Archeopyle apical (tA), the edge is clearly angular, nicked/incision deep, reflecting that there are 6-7? precingular plates. Operculum free;

Dimensions:
Typical specimen diameter 75 μm.

Affinities:
This new species is distinguished from Batiacasphaera euteiches (Davey, 1969) by the larger and thinner cyst and uncertain stratigraphy; distinguished from B. micropapillata by its large cyst, dense and separated surface particles; distinguished from B. macrogranulata, B. reticulata (Davey, 1969) by its ornamentation.
