Mystery orchard wasp - Sierolomorpha canadensis

Size: 4 mm
One of the "mystery" wasps I vacuumed out of the apple tree canopy as part of my MS thesis work - I've been using Borror et al 1989, and can't seem to key this one out. I originally thought Bethylidae due to dorsoventrally flattened body, head jutting slightly forward, and widened middle of femora on the forelegs. But the wing venation doesn't match at all. Nor did the wings seem right for Braconidae (due to the small costal cell). Your help much appreciated!
That said, our lab acquired this spiffy new scope with attached camera. I know BugGuide's preference is for live subjects, so I can certainly limit my submissions to ID questions (of which there will be more- I'm still learning). But if you are looking for more detailed photos of tiny parasitoid wasps, I've got lots and love playing with the new scope. Thanks! Stacy
