Description
Size: Length of lorica 161-196 µm; maximum width of lorica 126-170 µm.

Dorsal and ventral plates soldered together for three-fifths length of lorica, where they diverge and are united to a third plate, the basal plate. Dorsal margin with six spines. Lateral always longer than medians, medians longer than intermediates. Mental margin flexible, elevated in the middle. Posterior spines vary in length and position of origin but may be absent.
