Glossaulax reclusiana, also known as Recluz's moon snail, is a species of sea snail in the family Naticidae, the moon snails. It is named for French amateur malacologist César Auguste Récluz.
(Original description in Latin) The shell is ovate-conical and swollen, with a smooth or slightly striated surface. It is grayish-lead in color, whitish at the base, and features a dark band around the suture. The umbilicus is large and mostly covered by a callus, which is unevenly divided by a groove. The columella is heavily calloused at the top, white in the upper part, and marked with a dark spot in the lower part. The aperture is ovate-semilunar, with a small channel at the top, and is white to brownish on the inside. The shell can reach in height.

G. reclusiana lives in shallow bays and lagoons from the intertidal zone to depths around .
Like all moon snails, G. reclusiana is predatory. It feeds on other mollusks, including Callianax biplicata and Chione fluctifraga.
