Vallonia costata is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.^[2]

Description

For terms, see gastropod shell

The 1.1-1.6 x 2.2-2.7 mm shell has 3.2-3.3 whorls. Whorls are slightly angular at the periphery with deep sutures. The shell is flat with regular and widely spaced ribs. The shell is striated between the ribs, the last whorl is descending. The almost circular aperture is oblique (inclined downwards) and in adult specimens broadly reflected. The lip is thickened and reflected. As in other Vallonia, the umbilicus is very wide. The shell is ivory-white. For differences from Vallonia pulchella see that species.
