Original Description

Translated from French: Diagnosis: same features as those of the genus for which this form is the type species. Very low trochospiral test; the very flat profile is truncate even in the last chamber, lending the species its characteristic appearance. The poreless peripheral band reaches the last chamber (there, often perforate, cf. fig. 1d). The beaded double keel, not found in the last chamber, runs along the margins of the peripheral band in the remaining chambers.

Mêmes caractères que ceux du genre dont elle est l'espèce-type. Le test est une trochospire très basse: le profil très plat est tronqué même au niveau de la dernière loge, donnant son aspect caractéristique à l'espèce. Le bandeau périphérique imperforé atteint la dernière loge (sur celle-ci. il est souvent perforé, cf. pl. 2. 68 M. Caron fig. 1d). La double carène pustuleuse, qui le borde sur toutes les autres loges, ne se rencontre pas sur cette dernière loge.
