This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

The genus was determined using 'An Introduction to the Aquatic Insects of North America' by Merritt, Cummins and Berg (2008). The species was undetermined because of the lack of a key for the western nymphs. Most were found along the edge of the river, where the current was slow. The substrate was mostly sand and small gravel with fine silt and organic matter. They range in size from 6- 8 mm (excluding cerci).
These were found in the Russian River. They were found in an area that I had sampled many times before over four years and hadn't found any. I have found them in many small streams that feed into the Russian but this is the first time I have actually found them in the Russian.
They appear to be a separate species as well, given that they have white spots on the head and the abdominal terga are different. The others can be seen here http://www.troutnut.com/topic/9046/Ameletus-and-Paraleptophlebia and here http://www.troutnut.com/topic/8596/Paraleptophlebia-helena#41842
