This is a spectacular image ...
... (IMHO). I think this is likely Neodusemetia sangwani, a species introduced from India into Texas for the biocontrol of a mealybug, and previously recorded from Orange County, CA. The clincher would be if the antenna club was white ... which unfortunately is missing from your specimen.

 
White tipped antennae
It does have white tipped antennae! In my enthusiasm with brightening the photo, they were bleached out. We have found Neodusemetia sangwani many years ago... I should have recognized it. Thank you!

 
Comment by Dr. Noyes...
"Yes, definitely Neodusmetia sangwani. They are rare in Malaise traps (I do not think they climb very well) but can be very common in yellow pan traps in the right place, even in California.

 
Presence in Malaise traps
It amazes me that they will sometimes climb all the way to the opening of the Malaise trap! It is very uncommon, but I do find them every once in a while in the hundreds of MT samples that I look through per year. I am not 100% that each specimen I see is this species, though. Is the white tipped antennae the main character that distinguishes them from other brown wingless encyrtids?
