Thyrinteina arnobia (Lepidoptera: Geometridae) is the major defoliator of eucalyptus plants in Brasil in the last 50 years.
Since them, no parasitoid had been recorded for eggs of this pest in the field. In te lab we demonstrated that some kind of substance on the surface of these eggs protect them.
In 2017, we a found a parasitoid in eggs of Thyrinteina arnobia (Lepidoptera: Geometridae) in the field.
I would like to know who can identify this parasitoid. The quality of the photo is very poor but I can take better ones if necessary.

Hello Jose:
They are Eulophidae-Tetrastichinae wasps, very likely in the genus Aprostocetus sp. male on the left and female on the right. Very unusual as egg parasitoids on lepidoptera.

Dear Luis,
Sure, its is very unusual. This is the first time I have seen it in 45 years as forest entomologist in Brazil.
Thanks for your answer,

Dear Dr. Zanuncio,
I totally agree with the answer of the colleague @Luis Miguel Constantino.
I have some experience with Aprostocetus identification and I would like to try get your parasitoid identity.
Best,
Tiago
