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.

Thanks, Matt. Yes, those senior moments are occuring with greater frequency. It sucks to get old, but as the cliche says, I suppose it's better than the alternative.
