Encyrtidae? - Psyllaephagus bliteus - male

Encyrtidae? - Psyllaephagus bliteus - Male
Rio Rico, Santa Cruz County, Arizona, USA
April 7, 2017
Size: 2 mm
On March 23, 2017, I cut several Eucalyptus leaves, that were infested with lerps of Glycaspis brimblecombei, into two 1-gallon-size Ziploc bags and paper towel hoping to obtain parasitoids. Today, I noticed this wasp inside one of the bags. References mention Psyllaephagus bliteus as a parasitoid, but it does not appear to match the image posted on BG.

Moved from Encyrtids.

Comment by Dr. Noyes…
"I think the problem is that the males and females of this species (and most others) look quite different, especially in the structure of the antennae. The image in the UCD is of a female whilst your image and that on the French site are of a male".

See reference here.

I didn't consider the possibility of sexual dimorphism. I'm glad BG now has both male and female specimens now. Thank you Ross!

So, apparently, the projection from the end of the metasoma is not an ovipositor, as one might have suggested from the image.


Encyrtid (female)…
This is quite fascinating since there is an online French arthropod identification website here, that has identified an encyrtid they found in France as Psyllaephagus bliteus, which appears to be very similar to your own image. They even mention why they think it is this species (use Google translate). As you mentioned, however, other images, that do not look as similar, have also been identified as this species. This species appears to be the only known host in our area for Glycaspis brimblecombei. Will ask Dr. Noyes for his better judgement on the genus or species.

See reference here.

Their images appear to match mine. To my eyes, the overall appearance of these wasps is identical. I was especially interested in the antennae that look pretty much the same. Could it be that there are more than one parasitoid species here?
Will the "real" Psyllaephagus bliteus please stand up? :-)
Thank you Ross!
