Chytroeisphaeridia gochtii
Chyrtroeisphaeridia gochtii, (Dodekova, 1975), Jansonius, 1986
Originally Tectatodinium, subsequently Dodekovia, thirdly (and now) Chytroeisphaeridia.
Stover and Williams, 1987, retained this species in Tectatodinium Wall, 1967.
Lentin and Williams, 1989, followed Jansonius, 1986, and included it in Chytroeisphaeridia.
Holotype: Dodekova, 1975, pl.3, fig.10
Locus typicus: Gurkovo, NE Bulgaria
Stratum typicum: Late Bathonian

Original description as Tectatodinium gochtii: [Dodekova, 1975, p. 31]:
Description:
Ovoidal dinoflagellate cyst. The wall is thick, two-layered. The inner layer is thin, the outer-thick (2.5 µm), with fibrous structure which can be established in optical section of the wall. Surface fine reticulate. On the apical end a thickening of the outer layer is found, which forms a strongly rounded, short apical horn. Furrows are not to be seem.
The archaeopyle is precingular, one plate.
Affinities:
The apical thickening and the pointing of the apex distinguish Tectatodinium gochtii from T. pellitum Wall 1967.
