Ampelita galactostoma is a species of tropical air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Acavidae.
(Original description in Latin) This solid, convex-orbicular shell, tawny in color, exhibits oblique striations and a granular texture under magnification. It features an obtuse apex and four and a half slightly convex whorls. The penultimate whorl is keeled, and the body whorl descends towards the aperture. The base is separated from the moderately sized, perspective umbilicus by a subangular margin. The aperture is very oblique, oval, and white within. The simple peristome is brown-bordered, and the columellar edge is white and slightly dilated at the top.
This species is endemic to Madagascar.
