Diplotesta bidigitata Manum and Cookson, 1964
NOW Wallodinium. Originally Diplotesta (generic name illegitimate), subsequently (and now) Wallodinium. Following I.C.N. Article 55.1, the species name Diplotesta bidigitata is validly published even though the generic name Diplotesta is illegitimate.
Holotype: Manum and Cookson, 1964, pl.5, fig.6
Locus typicus: Graham Island, Arctic Canada
Stratum typicum: Late Cretaceous
Original diagnosis: Manum and Cookson, 1964, p.25
Shell roughly crescent-shaped in lateral view, apices blunt, usually elongate and more or less curled. Capsule asymmetrically biconvex or concavo-convex, prolonged at each end into a hollow, finger-like process. The walls of both shell and capsule are smooth. The shell opens by a break at one end.
Dimensions: Holotype: 65 Ám long as measured from apex to apex, 32 Ám across; capsule 57 x 31 Ám. Paratype: shell 85 x 34 Ám, capsule 56 x 28 Ám.
