Streptaxidae is a family of carnivorous air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. Six Streptaxidae subfamilies are accepted in the 2005 taxonomy of the Gastropoda by Bouchet & Rocroi.

Contents

Streptaxidae are carnivorous except for one species Edentulina moreleti, which is herbivorous. All streptaxids have well-developed radula, except Careoradula perelegans, which is the only known terrestrial gastropod without radula.

Altogether 66 species from the family Streptaxidae are listed in the 2010 IUCN Red List.

Distribution

The historical area of origin of the Streptaxidae is probably Gondwanaland.

The Recent native distribution of Streptaxidae includes South America, Africa, Arabia, Madagascar, Seychelles, Mayotte, Comores, Mauritius, Réunion, Rodrigues, India, Sri Lanka, Andamans, South-East Asia and the Philippines. The genus Gibbulinella is found in the Canary Islands.

2005 taxonomy

Only the one family, Streptaxidae, was recognized within the Streptaxida Streptaxoidea in the taxonomy of Bouchet & Rocroi (2005).

There are 6 subfamilies in the family Streptaxidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

  • Streptaxinae Gray, 1860 - synonym: Artemonidae Bourguignat, 1889
  • Enneinae Bourguignat, 1883 - synonym: Streptostelidae Bourguignat, 1889
  • Marconiinae Schileyko, 2000
  • Odontartemoninae Schileyko, 2000
  • Orthogibbinae Germain, 1921 - synonyms: Gibbinae Steenberg, 1936; Gonidominae Steenberg, 1936
  • Ptychotrematinae Pilsbry, 1919
  • 2010 taxonomy

    Sutcharit et al. (2010) have established a new family Diapheridae within Streptaxoidea and they have added two genera Diaphera and Sinoennea into Diapheridae.
