Added photo

Added an anterior photo, which has one of the tarsi more in focus. Also, there are tons of whiteflies around here, especially ones like this.

Aphelinid…

There is no narrowing between the propodeum and the gaster, suggesting an aphelinid. This feature excludes eulophids. The postmarginal vein is often absent in this group as well, which is not the case with eulophids. The number of whiteflies in the area is also suggestive since they are a major host for this group.

The front tarsi are four segmented in your latest image (can also be five in this group) which excludes trichogrammatids.

See reference here.

Thanks. Now that I think abou

Thanks. Now that I think about it, this location is probably a full mile from the big whitefly-covered oak I was thinking of.

Dr John Pinto says that according to Roger Burks at UC Riverside

"...it's a eulophid -- looks like Euderomphale, one of the whitefly parasitoids"

i'm inclined to make a genus page and move there the pics tentatively

Moved from Ants, Bees, Wasps and Sawflies.

Whitefly parasitoid

Possibly a species of Entedononecremnus. Universal Chalcidoidea Database doesn't list any Euderomphale species in Texas, which of course doesn't mean there aren't any. Did you collect the specimen or just take these pictures? I'd love to look at the specimen, or specimens, if you have them.

Not Entedononecremnus

This is probably Euderomphale.

Thanks...

...for the info and interest. I did not collect the specimen, unfortunately.

… John Schneider, 2 December, 2014 - 12:58pm

No problem

If you ever do collect one, let me know!

Re: Euderomphale

Hi, Zachary. I collected one today: https://bugguide.net/node/view/2129871
It emerged from a whitefly pupal case.

Schauff

Dr. Michael Schauff says: "This is one that would fool most people most of the time!! It is very similar in habitus to a number of aphelinids and has that aphelinid 'Look'." He also points out that Aphelinidae is probably not a monophyletic group. I should point out that in 1994 Dr. Schauff coauthored a paper with John Lasalle concerning the systematics of Euderomphalini.

Not Entedoninae

My chalcid contact says it is either Aphelinidae or Trichogrammatidae depending on the number of tarsal segments (3 in Trichogrammatidae), which he isn't able to see well enough to count.

… Bob Carlson, 8 July, 2014 - 1:27pm

Rescinded

My chalcid contact rescinds and apologizes for his prior conclusion and concurs with the Burks ID related via Pinto. He points out that he would never have thought this to be a eulophid, but after looking at the Burks key for the group, he says it is obvious that he was wrong.
