Shells minute, rissoiform, often elongate. Without anatomical informations, it is difficult to separate this family from many other.
 

Shell elongate, imperforate, whitish translucent, with a weak microsculpture made up of thin sinuous radial ribs crossed by slightly weaker spiral microstriae, the latter being more visible on the abapical part of the whorl. Protoconch more globular, less obtuse than in the genus Mifsudia.
 

Shell elongate, much more slender than in Atomiscala, Cima or Mifsudia, tapering, imperforate, whitish translucent, with a marked sculpture made up of sinuous longitudinal folds crossed by slightly weaker spiral microstriae, the latter being more visible on the abapical part of the whorl. The genus differs from most of the others by its stronger sculpture, and from Coenaculum, in which the sculpture is also conspicuous, by the globose protoconch.
