Shell description

The

Suture is slightly oblique.[3]

Aperture is quite piriform, or obliquely cordate, with 1 parietal tooth (sometimes with another punctiform one), 2 columellar teeth, the lower very small, often wanting; 2 short, high, equal, immersed teeth in the palate, bounded by a reddish-brown streak in front. Peristome is weak, expanded, the margins delicately united; outer margin not impressed, scarcely produced angularly forward.[3]

The width of the adult shell varies from 1.25 to 1.5 mm, the height from 2-2.25 mm.[3]

Vertigo lilljeborgi, compared with

Vertigo moulinsiana, is much smaller, more glossy, its whorls are more tumid, and its thinner lip lacks the broad, almost colorless margin of the latter.[3]
