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

(Original description in French) The white shell is perforated and slightly depressed, with the upper whorls and protoconch distinctly elevated.

A ridge forms just above the constriction of the body whorl, filling the suture cavity to a variable extent depending on the shell's age.

The peristome is double and reflexed, shaped like a horseshoe with its concave side facing the umbilicus.

The operculum is horny, multi-whorled, circular and concave on the outside, with a central nucleus protruding internally.
