If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

K. Bandel 2007The conical spire is ornamented by spiral ribs of which the median forms a weak keel on the rounded whorls with distinct sutures. The outer lip is wing-like and expanded to connect to the spire almost to its top. Its general shape resembles that in Wateletia with rounded median lobe and a posterior spine, which in contrast is free of the spire. Also the margin of the large lobe has short spikes. The lobe continues to the tubelike siphon forming a sinus at its inner margin. The callus of the inner lip forms a narrow ribbon that continues as ridge onto the spire and forms a cleft between it and the inner side of the outer lip, as is characteristic to the Hippochrenidae.
