Sphincterochilidae is a taxonomic family of medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[2]

Zilch, 1960 (1910)[1]

In the fossil record, Sphincterochilidae are known from the upper Eocene to the Holocene.[3]

Distribution

The distribution of Sphincterochilidae includes the western-Palearctic zone.[4]

Taxonomy

The following two subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005):[2]

  • subfamily Sphincterochilinae Zilch, 1960 (1910) - synonyms: Calcarinidae Pallary, 1909[5] (inv.); Albeidae Pallary, 1910.[6] Sphincterochilidae is a conserved name to take the priority of Leucochroidae Westerlund, 1886.[7][2][8]
  • subfamily † Pseudoleptaxinae H. Nordsieck, 1986[9]

Genera

Genera within the family Sphincterochilidae include:

Sphincterochilinae

† Pseudoleptaxinae

  • † Pseudoleptaxis Pilsbry, 1895[10] - type genus o the subfamily Pseudoleptaxinae[2]

Ecology

Sphincterochilidae land snails are xerothermophilous, i.e. they are well adapted to hot, arid places.[3]

gollark: That seems excessive.

gollark: 6_4: give me the code or face my wrath.
