Diversity[1]
58 genera

Streptaxidae is a taxonomic 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.

Streptaxidae are carnivorous except for one species Edentulina moreleti, which is herbivorous.[3] All streptaxids have well-developed radula, except Careoradula perelegans, which is the only known terrestrial gastropod without radula.[4]

Altogether 66 species from the family Streptaxidae are listed in the 2010 IUCN Red List.[5]

Distribution[edit]

The historical area of origin of the Streptaxidae is probably Gondwanaland.[6]

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.[1] The genus Gibbulinella is found in the Canary Islands.[1]

Taxonomy[edit]

2005 taxonomy[edit]

Only the one family, Streptaxidae, was recognized within the Streptaxida Streptaxoidea in the taxonomy of Bouchet & Rocroi (2005).[7]

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[8] - synonym: Streptostelidae Bourguignat, 1889
  • Marconiinae Schileyko, 2000[9]
  • Odontartemoninae Schileyko, 2000[10]
  • Orthogibbinae Germain, 1921[11] - synonyms: Gibbinae Steenberg, 1936; Gonidominae Steenberg, 1936
  • Ptychotrematinae Pilsbry, 1919[12]

2010 taxonomy[edit]

Sutcharit et al. (2010)[1] have established a new family Diapheridae within Streptaxoidea and they have added two genera Diaphera and Sinoennea into Diapheridae.[1]

Genera[edit]

Genera in the family Streptaxidae include:

Streptaxinae

Enneinae

Marconiinae

Odontartemoninae

Orthogibbinae

Ptychotrematinae
