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.
