Moved from Siphlonurus.

Moved from Mayflies.

Probably Callibaetis
like your other specimen

large size...
and short antennae seem to suggest Siphlonurus.

supports my initial suspicions but wasn't sure as I couldn't see much of the gills in the first pic.

Sorry to play yo-yo with this one...
but the bifid claw on the foreleg in Tom's new photo would seem to indicate that Siphloplecton was probably the correct move.

I just saw it after reinspecting the 2nd picture..moving it back...
