Thermacarus nevadensis Marshall, 1928

Nevada water mite

 

 

Taxonomy & Nomenclature

 

 

Conservation Status

After 12 July 1972 (Collins et al. 1976:1223)

It seems that this species still exists (see [url=http://extinctanimals.proboards.com/thread/1756/water-mite]here[/url]). Although, whether it was actually rediscovered or was mistakenly thought to be extinct but was never really threatened with extinction is unclear at this stage. It was apparently still alive in mid-July 1972 (Collins et al. 1976:1223), and so its extinction must have taken place quite recently, if indeed it did. Any information on its current conservation status would be very welcomed.
