Gorkadinium
From Fensome et al., 2019:
Gorkadinium, Loeblich Jr. and Loeblich III, 1966, p.93.
Substitute name for Tetrasphaera Górka, 1965, p.307 (an illegitimate name).
Type: Górka, 1965, pl.2, figs.6a–b, as Gorkadinium rarum.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description Tetrasphaera: [Gorka, 1965]:
Description:
Theca roundly rectangular, with a membrane of the same form. Transverse furrow and tabulation difficult to define. Short spines on the sutures delimit the plates. Theca and membrane finely reticulate.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Stover and Evitt, 1978, p. 231:
Remark:
The type of archeopyle on Gorkadinium is unknown; however, Davey (1969, p. 132) remarks that Gorka indicated to Sarjeant that her genus differs from Microdinium only in having a feebly marked tabulation and short spines on the plate boundaries. This observation would suggest that Gorkadinium has an apical archeopyle.
