Facelina quatrefagesi was considered as a synonym of Caloria elegans, but it is morphologically very similar and different valid species.^[2]

The size of the body varies between 20 mm and 35 mm.

This marine species occurs in European waters from the British Isles to the Mediterranean Sea; also off the Canary Islands, the Azores and Madeira.
