Unless the setae are long (about 0.60-0.75 X the width of femur), Jason, that would seem to bring us (me) back to A. feropagus/lapponica or perhaps B. foemina. (See above.)

foemina should have larger hind wing pads than the acentrella twins. feropagus has shorter setae on the hind margin of the femur than lapponica

Hope that gets us somewhere.

Yes, back to nowhere. :)

Stay tuned, Kurt. There just may be some light at the end of the taxonomic tunnel....

Ha! Will do. BTW - those wingpads sure look light for a nymph as close to eclosion as the specimens eye development suggests.
