## Distribution[edit]

The type locality for this species is on the southern shore of Tresjön Lake, near Ronneby, Blekinge province, in Sweden.[3]

This species is known to occur in a number of countries and islands in Northern Europe including:

* Great Britain, Wales, Scotland
* Ireland
* Denmark
* Germany
* Scandinavia: Sweden, ...
* Latvia
* and other areas

## Shell description[edit]

The shell is ventricose, ovate, strongly glossy, very finely striate, chestnut horn-color. The shell has 5 whorls, rather rapidly increasing, convex, the last but little higher than the penult, double as high as the next earlier whorl, a little ascending in front. 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]
