Semisulcospiridae diversified from the Pleuroceridae about 90 million years ago, in the Cretaceous.[4]

Distribution

The family Semisulcospiridae occurs in western North America, the Far East of Russia, Korea, Japan, China and Vietnam.

Taxonomy

The family Semisulcospiridae was introduced as just a name (nomen nudum) by Morrison (1952),[1] without a diagnosis of the taxon. It is a valid taxon however, because its name has been used as valid.

2005 taxonomy

According to the taxonomy of Bouchet & Rocroi (2005), Semisulcospiridae was a subfamily within the family Pleuroceridae.[3]

2009 taxonomy

The subfamily Semisulcospirinae within the Pleuroceridae was elevated to family level as Semisulcospiridae by Strong & Köhler (2009).[4]

Genera

There is very high level of mitochondrial heterogeneity in apparent species of Semisulcospiridae (highest among gastropods, also with Pleuroceridae), that has not been sufficiently explained yet as of 2015.[5]

Genera within the family Semisulcospiridae include:

  • Semisulcospira O. Boettger, 1886 - the type genus
  • Hua[4]
    • Hua jacqueti
  • Juga H. Adams & A. Adams, 1854[4]
  • Koreanomelania[4]
    • Koreanomelania nodifila
  • Koreoleptoxis[4]
    • Koreoleptoxis globus
  • "Parajuga"[4]
    • "Parajuga" amurensis[4]
    • "Parajuga" 'calculus'[4]
