Pteromalus?

Pteromalus?
Desboro, Grey, Ontario, Canada
April 24, 2018
Size: ~2.5mm abdomen to head.
I collected 5 Pieris rapae chrysalis in the spring, some already had exit holes. About a dozen of these wasps turned up in the sealed container one morning. I beleive they were all the same sex, in retrospect I should have collected some, but I released them all in our garden.

I believe this is a female Pteromalus. I've read that femur colour can distinguish P. puparum (darker) from P. cassotis (lighter), but I'm not confident, nor do I know anything about other options.

Pteromalid…
At least thirteen species of pteromalid attack this species of butterfly. At least four, and probably more, are in the genus Pteromalus, a large and difficult genus to narrow down, especially with only this single image to work with.

Thank you Ross! I can be happy with Pteromalid, and will aim to get more to work from next time.
