Omalogyridae are a family of minute and microscopic sea snails, marine gastropod molluscs or micromolluscs in the informal group Lower Heterobranchia.[1] Adult shells are usually smaller than 1 millimeter.
This family is poorly known and is tentatively placed in the unresolved infraclass "Lower Heterobranchia". Studies of this group are sketchy and miss or omit the basic information about taxonomy or distribution. [2]
