Original description: Morgenroth, 1966, p. 6
Diagnosis: The new species of the genus Gonyaulax has the following tabulation scheme: 4", 6"", 6""", 1p, 1ppl, 1"""". The thin-walled shell is approximately spherical. Epitheca and hypotheca are of about equal size. The short apical horn has the form of two cylinders standing on top of one other, of which the upper one is narrower, so that there is a clear "step". The plates are weakly granulate. They are delimited by sutures formed by ridges with stronger granulation. Parallel to the plate-margins, weakly developed ridges may be developed, concentrically arranged, also with protruding granulation. The helicoidal girdle furrow is situated on the shell. It is bordered on both sides by a ridge with a more pronounced granulation and is displaced two girdle-widths on the ventral side.
Dimensions: length 55 (45/61) Ám, width 50 (47/53) Ám, pylome 22x28 Ám, apical horn 3-4 Ám. 75 measurements.
