Alycaeus rolfbrandti is a species of small land snails with a gill and an operculum, terrestrial gastropod mollusks in the family Alycaeidae.

[1] The protoconch of Alycaeus rolfbrandti (a species otherwise similar to the type species, Alycaeus eydouxi) is finely scaly/tuberculated in oblique lines at the end of the protoconch.

It is also strongly sculptured (mamillated), and at the end of the protoconch oblique striae can be seen.

The upper part of the spire shows regular, fine, low ribs without spiral striae.

The lower part of the spire shows long with dense, lamella-like ribs (very similar to those of Alycaeus eydouxi).
