Retusa truncatula is a species of very small head-shield sea snail or barrel-bubble snail, a marine gastropod mollusk in the family Retusidae[1]

The subspecies Retusa truncatula var. mammilata: is a synonym of Retusa mammillata (Philippi, 1836)

The shell is minute with a flattened spire and longitudinal striations. The colour of the living animal is white. The adult length is usually less than 4 mm.[2]

Distribution

This species occurs in South Africa, from False Bay to Durban in shallow estuaries. It is also known from northern Europe, the Mediterranean Sea and the Canary Islands.[2]
