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.

While we're onto stoneflies, who is the mid-sized to large "golden"/"tiger" stonefly with bright red legs. I'd caught some a while back and never ID'd them. I'm embarrassed to say I don't remember where I caught them (NY or CO) and don't have the time right now to dig through my journals. Are there any bright blood-red legged stones out there?

Hi Paul,
While we're onto stoneflies
Sorry about that. For some of you that may be wondering why I posted all the stonefly topics out of the blue, it's because I'm editing that section of the hatch Pages. The reason they show up in the forum is so that everybody: a. is made aware of the updates and, b. can comment on the determinations or taxa information.
who is the mid-sized to large "golden"/"tiger" stonefly with bright red legs
Based on your use of the word 'tiger', I'm assuming it was pretty brightly marked which makes me think it's a species of Perlidae, subfamily Perlinae (assuming it had obvious thoracic gills). The Acroneuriinae are rarely described this way. I doubt you took this specimen in CO. In the West, we have it a little easier because of only having one species of Perlinae, the monotypic Claassenia sabulosa. I have never heard of a variant described with red legs, though I guess it's possible. More than likely it came from your NY days and is some variant of the Perlinae species found there: Agnetina capitata, Neoperla occipitalis, Paragnetina immarginata, or P. media.
Anybody from NY run into a red legged perlid that can help with this?

Yes it's a Perlid. It's not C. sabulosa so it must have been NY. I'll have to go through my journals I guess -they are in book form and therefore not searchable. There was a time when I knew where everything in them was. Use it or lose it sort of thing.
