Bohaidina spinosa
From Fensome et al., 2019:
Bohaidina spinosa Xu Jinli and Mao Shaozhi, 1989, p.217–218,222, pl.1, figs.12–16; pl.2, figs.1–2; pl.3, fig.1; text-figs.2–4.
Holotype: Xu Jinli and Mao Shaozhi, 1989, pl.1, fig.12. Age: early Tertiary.
---------------------------------------------------------------------------------------------------
Original description: [Xu Jinli and Mao Shaozhi, 1989, p.222]: (from english abstract):
Diagnosis:
Autocyst biconical to subquadrata in ambitus. Girdle projections 2-3. Autophragm 1 µm thick, covered with nontabular granulatebaculate ornamentation; baculae pointed or slightly expanded distally, less than 1 µm across and 1.5-2.5 µm long.
Archeopyle, when discernible, combination of [tAa]+3Ia type. Operculum compound.
According to the cyst morphology this species can be subdivided into three forms: fusiforma, quadrata and spinosa.
(Provisional translation GSC: courtesy R. Fensome):
Dimensions:
40 - 55.5 (holotype 40) µm in length, 31 - 44.5 (holotype 34.5) µm in width.
