The above list shows us that the watermite fauna of the Alps is a rich one. Above 1800 

 meters there still live no less than 60 species and varieties. 



In Norway Thor (1901) has studied the watermite fauna in the mountains. He was 

 unable to find watermites above 1200 meters. Thor mentions the following species:

 am al)le to list the following species only:
