Encyclopedia
Lozekia transsilvanica is a species
of small air-breathing land snail
, a terrestrial
pulmonate gastropod mollusk in the family Hygromiidae
, the hairy snails and their allies. This species is also known as Hygromia transsylvanica.
horny grey, greenish or yellowish brown, extremely finely striated. The surface structure is with fine and short (0.08-0.25 mm) riblets (120-160/mm2). The shell has 5 weakly convex whorls
, that are rapidly increasing. The last whorl is inflated and with weak edge at periphery, slowly and straightly descending near aperture. The margin is straight and thin. The umbilicus is very narrow and almost covered by the reflected columellar margin.
The width of the shell is 5.5-6.5 mm. The height of the shell is 4.5-6 mm.
Lozekia transsilvanica differs from Lozekia kovacsi in its larger (120-160 per square mm in Lozekia transsilvanica, 180-500 in Lozekia kovacsi) and longer riblets (Lozekia transsilvanica 0.08-0.25 mm, Lozekia kovacsi 0.055-0.09 mm).

Description
Lozekia transsilvanica has the shellGastropod shell
The gastropod shell is a shell which is part of the body of a gastropod or snail, one kind of mollusc. The gastropod shell is an external skeleton or exoskeleton, which serves not only for muscle attachment, but also for protection from predators and from mechanical damage...

Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral growth of a mollusc shell. A spiral configuration of the shell is found in of numerous gastropods, but it is also found in shelled cephalopods including Nautilus, Spirula and the large extinct subclass of cephalopods known as the...
