The lauriidae are a worm - Family from the subordination of terrestrial snails (gastropod). The family includes almost 50 species that are native to the Mediterranean, Southeastern Europe, Asia Minor, the Black Sea region and the Central Atlantic Islands.

features

The housings are cylindrical to oval. Mostly they are small shapes. The postembryonic convolutions are usually ribbed radially. The mouth of the last turn usually rises from the turn level. The upper edge of the mouth is often almost straight, but not parallel to the suture. Usually two to seven teeth protrude into the mouth; the forms without teeth are rare. In the genital apparatus there is a penis with an epiphallus and a blind sac ( caecum ). The inner walls of the penis are provided with roughly spiral folds. The prostate has few acini ; it sits at the base of the albumin gland. There is also a penile appendix. The penis retractor is branched. The stalk of the spermathec has no glands; Diverticula are usually absent.

Geographical distribution and way of life

The family is widespread in the Mediterranean, Southeastern Europe, Asia Minor, Crimea, the Caucasus, and the Mid-Atlantic Islands ( Madeira , Azores, and Canary Islands ). Individual species have now also been introduced to other regions, for example. B. to North America ( British Columbia ) and New Zealand. The animals live in forests and meadows, especially under stones and in stone walls in dry, but also rather moist habitats under mosses and fallen leaves.

Systematics

The family Lauriidae is considered by Bouchet & Rocroi (2005) as an independent family within the superfamily Pupilloidea . In contrast, Schileyko (1998) interprets the taxon as a subfamily of the Orculidae .

annotation

  1. ↑ Jungbluth & von Knorre (2007) recommend the name Tagged Puppet Snails as a common German name for this family . The trivial name Labeled pupa snail describes the species Lauria cylindracea and the transfer of the species name to the entire family does not make much sense, especially since there is only one species of this family in Central Europe. MollBase , on the other hand, uses the common German name Genabelte Puppenschnecken for the genus Lauria . That is why the unambiguous Latin name Lauriidae is used here.
