Systematophora taiwaniana
From Fensome et al., 2019:
Systematophora taiwaniana Shaw Chenglong, 1999b, p.192, figs.120–125. Holotype: Shaw Chenglong, 1999b, figs.123–125. Age: Eocene.
---------------------------------------------------------------------------------------------------
Original description (Shaw Chenglong, 1999b):
Systematophora taiwaniana Shaw, sp. nov. (Figs. 120-125)
Holotype: slide OK-1 1788bl- (4); film PF40-33, PF40-34, PF40-35; Figs. 123-125 (Holotype at three foxus levels); CPC Micropaleontology Lab.
Description: Cyst spherical to subspherical, 43-51 µm wide, surface features with annulate complex of processes which are distally free, processes cylindrical to tapering with evexate tip, up to 18 µm long; apical archeopyle, operculum generally free, occasionally remains in place; no indications of parataulation, paracingulum, or parasulcus.
Stratigraphic occurrence: Eocene (OK-1 well, 1788m).
Derivation of name: the specific epithet taiwaniana is derived from the name of the type locality.
Dimensions: Holotype: overall 42 µm long, 52 µm wide, processes 11-18 µm long.
Remarks: the new species differs from Systematophora placacantha (Cookson & Eisenack) Davey et al. in having the surface features with annulate complex of processes which are distally free, processes cylindrical to tapering with evexate tip.
