Shell description
The original description (Adams, 1860)
reads: Testa ovata, tenuis, umbilicata, superficie cancellata; spira producta, apice obtuso. Apertura elongata, antice producta et integra; labio tenui, simplici; labro postice angulato, in medio recto, margine acuto. This genus nearly resembles ''

Life habits
Little is known about the biology of the members of this genus. As is true of most members of the
Pyramidellidae ''
sensu lato'', they are most likely
ectoparasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has ...
