Moved
Moved from Myzinum carolinianum.

Salvador: Again, if you're able to inspect the specimen, and you determine there is indeed a groove present on T7, then I think we can move this back to carolinianum...otherwise, see comment below.

 
Thank you Aaron
for all your hard work. Unfortunately, I released the specimen as soon as I was done with the photos. In cases like this, I wish I would have kept the specimen to be able to image needed characters. Sorry.

 
Double oops!
I must of read you "still had the specimen" on another post right before looking at this one...and confused them! (Mr. Magoo strikes again ;-)

Well, at least the myzine was happy to be released...and you have an idea of diagnostic features to try to photograph when you see them next.

Oops...my apologies. I jumped the gun here!
Bob Biagi caught an error on my part. After going through the characters in Robert Behrstock's similar post below:

       

...I neglected to carefully check yours here for the critical presence of a "medial crease or groove" on the terminal 7th tergum of the metasoma (i.e. "abdomen")...per couplet 3 of the key on pg. 33 of Kimsey(2009)...see also Figs. 10-12 on pg. 36 there for clarification.

It looks like what might give the intimation of a groove in the image above, could just be a piece of dust (cf. the 1st image). But it's also conceivable the groove may still be there, but subtle and partially obscured by the angle of view. If you still have the specimen, and can check the "T7 groove" character with a hand lens or scope, that could help clarify the ID situation.

If the groove on T7 is indeed absent, then to get a species ID one might have to study the genitalia (probably too difficult here!)...unless, per couplet 5 of the key, the mid-coxa are "dentate, lobate or broadly angulate on inner margin (as in Fig. 5)". In that case we may still have a chance to ID your specimen without having to dissect terminalia!

(PS: This situation is helping me to better appreciate Lynn Kimsey's used the phrase "Taxonomic Purgatory" in the title of her revision ;-)

Moved
Moved from Myzinum.

Salvador, this appears to be a disjunct per current literature
...see the comments under Robert Behrstock's images of a similar myzine from Hereford, Cochise County, AZ:

   

Yours is even further west! :-)

Moved from Thynnid Wasps.
