Alvania is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
They form a very diversified group within the Rissoidae family.




Description


Alvania as currently used may not be monophyletic.
The genus Alvinia has been synonymized with Alvania, until a consistent phylogenetic scheme emerges for the whole group. As of 2012, is sometimes considered a separate genus.
The genus Alvania comprises species with small shells with heights measuring between 1 mm and 7 mm. Their general shape is ovate-conical, reticulated with axial and spirals elements. They have a continuous peristome. Their coloration is variable.
Some species such as Alvania sculptilis have been named twice with the second naming becoming a junior secondary homonym. However, the genus Alvania as currently used has a very broad taxonomic extension, and these species may very well end up in different genera when a robust phylogeny becomes available.




Distribution


These marine species can be found worldwide (except in the antarctic and subantarctic regions). They can be found from intertidal depths to abyssal depths.
