Tropaeas is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
The surface of the shell is marked by strong axial ribs. The intercostal spaces are spirally pitted. The early teleoconch whorls are sculptured differently from the later ones. The shell is umbilicated and contains two columellar folds.
