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.[5]
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.[6]
Genera within the family Semisulcospiridae include:
- Hua S.-F. Chen, 1943 [4]
- Juga H. Adams & A. Adams, 1854[4]
- Koreoleptoxis J. B. Burch & Y. Jung, 1988[4]
