Original description: Cookson and Eisenack, 1960:
Characters of the genus. Shell membrane granular, pylome semicircular to nearly square.

G.L. Williams short notes on species, Mesozoic-Cenozoic dinocyst course, Urbino, Italy, May 17-22, 1999 - LPP VIEWER CD-ROM 99.5.
Xenikoon australis Cookson and Eisenack, 1960a, is ovoidal, slightly pointed anteriorly, containing a spherical endocyst with an apical pericoel and in some specimens a narrow ambital pericoel. Archeopyle intercalary, resulting from loss of 2a. Size: holotype length 59 µm, width 47 µm, endocyst length 47 µm, width 52 µm, range 50-70 µm long, 43-62 µm wide.
