What is "victorlemoinea"

Victorlemoinea is an extinct litoptern genus of the family Macraucheniidae.

This animal is considered a member of the Macraucheniidae family, but according to some scientific authorities, could just as easily be from the Sparnotheriodontidae, and is said to share some features with the didolodont family of mammals. Fossils referable to the genus have been found on Seymour Island.
