Mystery orchard wasp - Sierolomorpha canadensis - male

Mystery orchard wasp - Sierolomorpha canadensis - Male
Almar Orchards (Flint), Genesee County, Michigan, USA
June 26, 2009
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

Stacy--
thanks for your contributions! bring it on... we do need good pix of microparasitica -- images of preserved specimens are just fine.
this one i suspect to be a bethylid of sorts -- i'll show it around

 
Sierolomorphidae
Looks like a male Sierolomorpha sp. They're rarely encountered, so a very good thing indeed! They often get mistaken for bethylids, but the venation is too complex for that family. There are several species in North America and I don't have a key.

 
Great find
I have a pdf of Evans' review of the genus, plus another paper on a new species. I can send both of them to y'all if interested (do you have an email, Stacy?).

 
Sierolomorpha canadensis
Sierolomorpha canadensis (Provancher, 1888) based on Evan's key. Thanks George!

 
Thanks!
Thanks all for both the kind welcome and the great ID help! This is a brand new family for me, so it's pretty exciting. George, I'll email you separately about those papers.

 
Note the difference between t
Note the difference between the male antennae and those of the female that I just put a name on. Also the male is more pubescent. You might want to edit your information for the picture to note that this is a male (just check the box)
