Diagnosis Test discoidal, proloculus followed by elongate tubular second chamber, early whorls in short zigzag bends that are streptospirally wound about the proloculus, later becoming planispiral, interior with pillars similar to those of Triasina; wall calcareous, granular as seen in section, but probably recrystallized; aperture at the end of the tubular chamber. M. Triassic (Ladinian); China. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
