Summary of all sampling localities. 327 red dots represent material examined; 14 blue diamonds represent published accounts where material was not available for direct examination. Each of the 341 localities represent a generalized locality, not an individual collection event, as multiple events often occured in close proximity. In total, this map represents nearly 500 collection events. Note the absence of material from the Great Plains (e.g., Oklahoma, Kansas, Nebraska, and the Dakotas) and Alaska; these are areas that were sampled for water mites, but Torrenticola were not found.
