Torymus species groups
Is there a place we could find a listing of which species belong in which groups?
… Charley Eiseman, 24 May, 2014 - 5:30pm login or register to post comments

 
Yes
You will find a discussion of the situation and the reference here. The 1976 paper by Grissell is cited on this page.

Moved
Moved from "Parasitica" (parasitic Apocrita).

Thanks. Do all female torymids have a prominent ovipositor? If so, it seems there are ten males and no females.

Yes...
The literature maintains that the ovipositor is clearly exerted in females, though it may not always be long.

Chalcid wasp females can choose to fertilize or not to fertilize each egg they lay; unfertilized eggs will become males. Unfertilized females lay only male eggs; fertilized females lay either male or female eggs (females more often typically).

Question...
Do you have any lateral views, Charley?

Added shot...
of a different individual from the same batch. Let me know if you're looking for a specific detail, and I'll see if I have a shot that shows it well.

Torymid (male)...
If the individuals all look similar to these two images, then that's where I would leave them. You can see the enlarged hind coxae in the lateral view, which along with the wing venation, coloration, and distinct parapsidal sutures, points to this group.

See reference here.
