Staffordiidae

See text Staffordiidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Trochomorphoidea.

[3] Thus, it has been hypothesized that the Staffordiidae colonized its current area from the southern margin of the Asian part of the Eurasian Plate during the Oligocene period.

[6] Reproductive system of Staffordia: the dart-sac is small, globose, with a long cord-like attachment to a coronal gland.

[6] Comparison of shells of three Staffordia species: Staffordiidae is considered a sister group of all other families in the limacoid clade.

[3] The following cladogram shows the phylogenic relationships of this family and superfamily to the other families within the limacoid clade:[3] Staffordiidae Dyakiidae Pristilomatidae Chronidae Euconulidae Trochomorphidae Gastrodontidae Oxychilidae Trigonochlamydidae Parmacellidae Milacidae Zonitidae Helicarionidae Ariophantidae Urocyclidae Vitrinidae Boettgerillidae Limacidae Agriolimacidae This article incorporates public domain text from the reference.
