Trissolcus brochymenae
Sorry, I have not submitted before but have enjoyed the site for years.

happy to hear that --keep them coming!
images of any organisms, especially of expert-identified members of obscure, 'non-collectibe' taxa, are precious.
expanding the guide to include those rarely, if ever, photographed, arthropods whose images are hard to find, is a noble goal --and it's the direction i want to see BG evolve in

Trissolcus brochymenae
This is Trissolcus brochymenae, verified by Dr. Norm Johson, Ohio State University. This species falls into the flavipes group having orbital furrow expanded ventrally, hyperoccipital carina present, and notauli present. There are two color variations, this is the yellow scape and yellow leg version, the other is similar to Tr. euschisti having brown scapes and brown legs. I am currently rearing Tr. brochymenae, Tr. euschisti, Tr. basalis, Tr. hullensis (USA), Tr. halyomorpha, Tr. flavipes, Tr. mitsukurii, Tr. plautiae (Asia), Telenomus podisi(USA), Paratelenomus saccharalis (Japan), Ooencyrtus nezarae (Japan), undescribed Ooencyrtus sp. (France), and a unisexual Eupelmidae Anastatus sp. I have also had in colony Gryon pennsylvanicum (USA), Telenomus calvus (USA), and Ooencyrtus telenomicida (France). The photo is of a reared specimen, the original female was collected using Podisus maculiventris sentinel egg mass in April 2011. I did not expect such immediate response, I just noticed the guide had no Tr. brochymenae (it is one of my favorites).

Appreciate it...
Thanx for the confirmation. I look forward to seeing these additions, especially Paratelenomus.

thanks much for the explanation
you could just put the ID info in the "remarks" box -- like i just did -- to avoid questions

re: Trissolcus…
Telenomus and Trissolcus are very similar in their morphology. A dorsal view (at least) is required to determine the subtle differences. A determination that this is Trissolcus simply cannot be made based on this lateral view alone. Unless you are sure of the genus or species based upon your scientific background and experience, I would suggest placement at the subfamily level.

See reference here.

Given the fact that the species is identified, do you suppose there is reason to suppose the genus was misidentified? I would suppose that the species has been in culture.

Moved from Platygastridae.

Various web sources, including Taxapad, place Trissolcus in the Proctotrupoidea, family Scelionidae, subfamily Telenominae.

I had been oblivious to the junior synonymy of Scelionidae. I guess Taxapad is out of date on this.

thanks for the addition!
do you have a capture date for it? if so, please add.
would you please drop me a word offline to vmarfus on gmail? thanks.

I sent a note.
