This genus has been assigned in the course of time to different families by different authors: Rissoidae, Cerithiidae, Dialidae, Obtortionidae, Finellidae and Diastomatidae Morphological and anatomical studies by Winston Ponder in 1994 established that the genera Finella and Scaliola didn't belong in the above-mentioned families and he brought them in a new family Scaliolidae.[3] This was supported in 1982 by Healy through the study of the ultrastructure on the spermatozoa.[4]

Description

The species in this genus contain a small, elongated, conical shell without siphonal canal. The axial to spiral sculpture varies between weak and strong.

Distribution

The snails of this species are common to even abundant in shallow waters of the tropical Indo-West Pacific Ocean.
