Caenogastropoda incertae sedis

Caenogastropoda incertae sedis is a taxonomic grouping within the Caenogastropoda, a large and diverse order of gastropod mollusks. The term “incertae sedis” is Latin for “of uncertain placement,” and it is used in taxonomy when the exact phylogenetic relationships of a group are not yet fully understood. This means that the species within Caenogastropoda incertae sedis are considered caenogastropods, but their specific placement within the order is still being investigated.
