Ampelita lamarei is a species of tropical air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Acavidae.
(Original description in Latin as Helix stragulum) This narrowly umbilicated, very depressed shell is thin, minutely granulose under magnification, and longitudinally impressed with fine growth lines. Chestnut-brown with rare yellowish-straw spots, it features a sub-flattened spire with an obtuse apex and an impressed suture. Four flattened, rapidly increasing whorls are present, the upper 2.5 violaceous-brown, and the body whorl bordered with yellow at the suture. The body whorl is large, sub-depressed above, angulate-keeled slightly above the periphery, and has a convex, inflated base, sub-angulate around the umbilicus. The umbilicus area is dark chestnut, encircled by a pale yellow zone. The large, very oblique, elliptical-ovate aperture is bluish-white inside. The bluish-white peristome is widely reflexed, with margins joined by a thin callus, and the outer margin dilated medially and near the insertion.
This species is endemic to Madagascar.
