Wetzeliella (Apectodinium)
From Williams et al., 2017:
[Wetzeliella subgenus Apectodinium, Costa and Downie 1976, p. 608.
Type species: Wetzeliella homomorpha, Deflandre and Cookson, 1955 (pl.5, fig.7; text-fig.19)]
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Costa and Downie, 1976]:
Diagnosis:
A subgenus of the genus Wetziella with pericoel absent or confined to small areas at the base of the horns. At the archaeopyle margins the periphragm and endophragm are in close contact when both walls are observable.
The processes are randomly distributed over the test surface or some can be roughly arranged along part of sutural lines.
