I find myself embarrassingly stumped by this little beast. The tarsi are 5-segmented, 2 pairs of wings, >20 antennal segments, mandibulate mouthparts (at least palps visible). I am leaning towards a peculiar microhym, even though I admit the wings do not hinge together or strike me as particularly hym-y and keying to family becomes troublesome as there don't appear to be tibial spurs. My other guess was a microcaddisfly that lost its scales while stored in ethanol...

Collected in a malaise trap set adjacent to Kinbasket Lake.

Thanks in advance for any ID help!
