Vertigo ronnebyensis is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Vertiginidae, the whorl snails. [3]
The shell is deeply perforate, long-ovate, regularly finely striate, very glossy and reddish-brown in color. The shell has 5½ convex whorls. The last whorl is about equal to the penult, which is a third higher than the preceding whorl, which is double the height of the next earlier. Last whorl has a transverse callus of the same color near the aperture. Suture is very oblique, ascending to the aperture.[4]
Aperture is quite obliquely piriform, excised by the very oblique parietal wall. Aperture has 4 teeth: 1 parietal lamella, 1 conic tooth at the lower end of the sharply emerging, dark-colored columella; 2 short, widely separated, deeply immersed palatal folds. Margins are delicately united, the outer margin is weakly arcuate, nearly straight, the columellar margin is broadly reflected.[4]
The width of the adult shell is 1.15-1.35 mm, the height is 2.0-2.35 mm.[5]
