Original description: [Jiang, 1992, p. 81]:

Diagnosis:
A species of Carnarvonodinium with an ornament of fine grana.

Description:
Proximate cysts, elongate ellipsoidal with rounded antapex.
Apical horn may be present but quite inconspicuous. Autophragm only ( < 1 µm thick), surface covered more or less evenly with fine grana.
Archaeopyle apical, type tA. Accessory archaeopyle sutures clear, indicating 6 precingular paraplates. No other paratabular features observed. Operculum free in most instances but is attached in the holotype; separation is thought to be a preservation-preparation feature.

Dimensions:
Length 67-71 µm (with apex), holotype 71 µm; breadth: 34-37 µm.
