Batiacasphaera microreticulata, Shaw Chenglong, 1999b, p.180-182, figs.66-69,82-83.
Holotype: Shaw Chenglong, 1999b, figs.66-67.
Age: Eocene.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Shaw Chenglong, 1999b]:
Description:
Cysts spherical or lenticular with a characteristic microreticulate (pseudo-granulate) surface and thick autophragm (2-2.5 μm thick);
apical archeopyle, operculum generally free, occasionally remains in place, 33-54 μm wide.
No indications of paratabulation, paracingulum or parasulcus.
Dimensions:
Holotype – Overall 59 μm long, 45 μm wide, autophragm 2-2.5 μm thick, apical archeopyle 45 μm wide.
Other species - Overall 55-59 μm long, 45 μm wide, autophragm 2-2.5 μm thick, apical archeopyle 40-45 μm wide (n=3).
Affinities/Remarks:
The species differs from Batiacasphaera cassicula Wilson 1988 in being substantially smaller and in having microreticulate processes.
