Scutalus phaeocheilus is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the family Bulimulidae.

[2] When describing the nominate taxon, Haas already noted the relationship with Scutalus proteiformis.

[2] Scutalus proteiformis species, which has not been figured, was mentioned by Weyrauch (1967)[4] from northern Peru without further information.

[2] The height of the shell is up to 38.1 mm, 1.71 times as long as wide, deeply perforated, conical, with slightly convex sides and solid.

Colour is uniformly (greyish-)whitish, the upper whorls somewhat lighter in greyish-white specimens.

Columellar margin straight, broadly expanded and merging into the parietal callus, which is whitish and thickened in some specimens.
