Diplotesta glaessneri Cookson and Eisenack, 1960

NOW Wallodinium. Originally Diplotesta (generic name illegitimate), subsequently (and now) Wallodinium. Following I.C.N. Article 55.1, the species name Diplotesta glaessneri is validly published even though the generic name Diplotesta is illegitimate.

Holotypus: Cookson and Eisenack,1960, pl.39, fig.4
Locus typicus: Broome No. 3 bore, W. Australia
Stratum typicum: Oxfordian-?Aptian

Original diagnosis: Cookson and Eisenack, 1960, p.256
Shell cylindrical, straight or curved, distal end bluntly pointed, proximal end not diminishing in size and apparently rounded. In all of the many examples observed the proximal end of the shell has been open and the edge clean-cut; in a number of them, including the type, and the example shown in Pl. 39, fig. 5, the proximal wall has separated as a "lid", seemingly along a preformed line of weakness, and is to be seen still attached at one side.
The capsule has a thin, smooth wall and extends laterally to or almost to the shell membrane, the latter is either smooth or longitudinally striate (Pl. 39, Fig. 6). The capsule opens by means of a V-shaped apical split to one side of the middle line.
Dimensions: Holotype: length (without lid) 100 Ám, breadth 24 Ám, capsule 58 Ám long, 24 Ám broad. Paratype (Pl. 39, fig. 5) 80x38 Ám, capsule 62x38 Ám.
Range: length (without lid) 80-128 Ám, breadth 24-38 Ám long, 24-38 Ám broad.
