Wallodinium luna (Cookson and Eisenack, 1960) Lentin and Williams, 1973
Originally Diplotesta, subsequently (and now) Wallodinium.
Holotype: Cookson and Eisenack, 1960, pl.3, fig.21
Locus typicus: Wapet's seismic shot hole B1, N of Gingin, W Australia
Stratum typicum: ?Late Albian-Cenomanian

G.L. Williams short notes on species, Mesozoic-Cenozoic dinocyst course, Urbino, Italy, May 17-22, 1999 - LPP VIEWER CD-ROM 99.5.
Wallodinium luna (Cookson and Eisenack, 1960a) Lentin and Williams, 1973. Diagnosis, shell half-moon shaped, tapering toward the two bluntly pointed ends and containing a slightly concavo-convex elongate capsule which narrows distally toward somewhat pointed apices. Wall of both shell and capsule smooth. Size: holotype, length 70 µm, width 30 µm, endocyst length 54 µm, width 20 µm.

Original description: Cookson and Eisenack 1960, p. 10-11: Diplotesta luna Diagnosis: Shell half-moon shaped, tapering towards the two bluntly pointed ends and containing a slightly concavo-convex elongate capsule which narrows distally towards somewhat pointed apices. Wall of both shell and capsule smooth.
Affinities:
Cookson and Eisenack 1960, p. 11: Diplotesta luna
Six examples have been found, all of which are imperfect. However, they seem to constitute a species which is distinct from the Upper Jurassic - Lower Cretaceous species Diplotesta glaessneri Cookson and Eisenack 1960(2), in the more deeply concavo-convex outline and the more pointed apices of the shell.
