    Taxonomy from Bandel et al. 1983.

    Diagnosis from Bandel et al. 1983, p. 411:"First chamber 0.5 - 0.6 mm wide and spherical, following chamber of equal height, but rapidlx increasing in width. Beyond the 3rd - 4th chamber, septa are less distinct and appear, if at all, as a transversal striation of very slow increase in width. At a length of 3 mm the conch develops a dorsal median keel and two lateral keels. Apical angle between 18-30°."
