Macromphalus is a genus of very small sea snails, marine gastropod mollusks or micromollusks in the family Vanikoridae.

General characteristics

(Original description) The shell is fusiform, with an elevated spire and an ovate aperture. The outer lip is sharp, and the umbilicus forms a narrow, linear opening.

(Described as Couthouyia) The shell is ovate, with a deep, broad umbilical chink and an acuminate spire. The whorls are convex and bear intersecting sculpture, while the body whorl is inflated. The sutures are impressed.

The aperture is semi-ovate. The inner lip is straight, narrow, and free, widening anteriorly, and the umbilical chink is elongated. The outer lip is simple and curved, with a sharp, entire margin.
