There aren't all that many baetids reported from Alaska, but I couldn't figure out what this one is. I didn't have a lot of time to look at keys, but here's the whole list of reported Alaskan baetids, with the ones I could obviously eliminate crossed out (and now some that you've eliminated, too):

Acentrella feropagus
Acentrella insignificans
Acentrella lapponica
Acentrella turbida

Baetis bicaudatus
Baetis foemina
Baetis tricaudatus
Baetis bundyae
Baetis flavistriga

Callibaetis

Diphetor hageni

Plauditus dubius

Procloeon pennulatum
