Original description: Alberti 1959, p. 99-100
Shell flattened, elongate. Epitheca mostly a sharp-cornered triangle, distally narrowing into along horn. Transversal furrow mostly absent and if present slightly deepened. Two long antapicalhorns which, like the apical horn, sometimes bear a fine longitudinal striation. Inner body oval, positioned close to the shell.
Additions: The species is characterized by the long horns, which narrow distally and which are pointed or slightly blunt. The horns are almost equal in length. The membrane of the armour is soft, transparent and sometimes finely punctate. A rounded trapezium-shaped archaeopyle is located closely below the apex. Dimensions: Lenght central body: 110-210 µm; width central body: 40-50 µm.
