Citation: Gonyaulacineae (Autonym).
Diagnosis: Gonyaulacaleans in which the hyposomal tabulation is sexiform, i.e. in which the first antapical homologue (*1'''') contacts the sixth postcingular homologue (*6''') and in which the posterior intercalary homologue (*1p) extends further to the anterior than the posterior sulcal homologue (*ps). Distinctive postcingular horns are absent.
