  • Gastrocoptinae
  • Hypselostomatinae

Hypselostomatidae Zilch, 1959

Distribution

The distribution of the Gastrocoptidae is nearly worldwide, although family is extinct in Europe since Pleistocene, except one species in Northern Caucasus. In fossil record from Paleocene.

Taxonomy

For some time was considered as a subfamily in Vertiginidae, some species of these two families are very similar by the shell's characters.

Genera in the family Gastrocoptidae include:

Subfamily Gastrocoptinae Pilsbry, 1918

Subfamily Hypselostomatinae Zilch, 1959 - distributed mainly in Southeastern Asia and Australia

  • Hypselostoma Benson, 1856 - the type genus of the subfamily
  • Acinolaemus Thompson & Upatham, 1997
  • Anauchen Pilsbry, 1917
  • Angustopila Jochum, Slapnik & Páll-Gergely, 2014
  • Antroapiculus Panha & Burch, 1999
  • Aulacospira Möllendorff, 1890
  • Bensonella Pilsbry & Vanatta, 1900
  • Boysia L. Pfeiffer, 1849
  • Boysidia Ancey, 1881
  • Dentisphaera Páll-Gergely & Jochum, 2017 - endemic to the caves in Northern Vietnam[5]
  • Gyliotrachela Tomlin, 1930
  • Krobylos Panha & Burch, 1999
  • Montapiculus Panha & Burch, 1999
  • Pseudostreptaxis Möllendorff, 1890
  • Tonkinospira Jochum, Slapnik & Páll-Gergely, 2014
  • Paraboysidia Pilsbry, 1917
gollark: That's silly, QM only gives you a probability distribution IIRC.
gollark: This is only 16GB of memory, which you can get on a reasonable workstation now.
gollark: * 2^34, even better
gollark: Anyway, single-precision floats can hold 2^32 values. Assuming you want to map each float to another float, you therefore only need 2^36 bytes of memory to store the lookup table.
gollark: I agree.
