Wetzeliella articulata subsp. scabrata
Wetzeliella articulata subsp. scabrata (Shaw Chenglong, 1999a, p.45, figs.49–57) Williams et al., 2015, p.317.
Originally Wetzeliella articulata var. scabrata, subsequently (and now) Wetzeliella articulata? subsp. scabrata. Questionable assignment: Williams et al. (2015, p.317).
Holotype: Shaw Chenglong, 1999a, figs.49–51.
Age: Eocene.
Original description (Shaw Chenglong, 1999a):
Wetzeliella articulata Eisenack scabrata C. L. Shaw var. noν. Figs.49-57
Holotype: Sample slide OK -1 1788- (1); film PF34 PF34-7, PF34-8 (Holotype at three focus levels); Figs. 49 1; CPC Micropaleontology Lab.
Description: Cyst intermediate to large, compressed peridinioid, with apical, two lateral and two normal to relative reduced antapical horns. The wall of cyst thin and well-covered with appendages; processes numerous, tubiform with bifid or entire tips, fairly long (up to 15 μm), relative small and closely clustered on distal part of horns (2-4 μm), surface view with scabrate ornamentation; endocyst smooth, thin-walled and broadly elliptical in outline. Intercalary archeopyle, operculum sometimes attached along anterior margin, generally free.
Dimensions: Holotype: Overall length 127 µm long, breadth 113 μm wide, length of cyst 78 µm long, breadth 80 µm wide, surface features with tubiformed processes, the tubiformed processes may up to 11 µm long.
Dimensions: Overall length 85-162 µm long ,breadth 90-113 µm wide, length of endocyst 78-92 μm long, breadth 78-95 µm wide, surface features with tubiformed processes, the tubiformed processes may up to 12 µm long (n=6).
Stratigraphic occurrence: Eocene (OK-1 well, 1788m)
Derivation of name: Latin, scabrata is named after the scabrate ornamentation of the cyst.
Remarks: The new variety resembles to Wetzeliella articulata Eisenack in having a roughly similar outline. However it differs from that in having a smaller size and the surface view with granulate ornamentation.
