It is already packed, so to speak.
Thanks for your detective work! That is good news. I still feel regret that I smugly stated that I would easily find the dark winged version of this family that had very dark veins on the hindwings. I have downgraded that to it is possible I have will have one.

A note on how I am preserving as many specimen as possible in one pill container. I keep them separate with pieces of tough, absorbent bamboo paper towels. But once they are in, they are in. I want to keep them as safe as possible. At the bottom there is a ribbon of bamboo towel that runs under the first layer and runs up the sides of the pill bottle. I envision the recipient being able to take each end of the ribbon and pull all the layers out one at a time, or all at once. I am making some assumptions, but it seems like it would work. If there is empty space still left when I post it I will fold up another piece to hold it in place. My main worry is just how resistant to evaporation my prescription bottle will be. Judging from how much force the "child proof" cap requires, I guess to real question is do you have a bodybuilder handy who can open it? Then again I know you lift weights if you are still hefting that camera of yours!

So, anyway when I seem to be pulling pictures out of my hat, I am just going back and seeing if I can find a picture long since taken (as you probably know). I sometimes take a lot of images. It try to review them all, and guess which are of interest. Your questions have led me to realize how limited most of my pictures are. The flash is pretty much necessary. But it can hide a lot!

OK, that ventral imaged helped...
Species of Peripsocus lack visible setae on forewings, but pecies of Kaestneriella do have setae on forewing. We got the genus!

If you could take a ventral close up of the tip of the abdomen (as "level" as possible) I might be able to key it to species.

THis could be in the genus ...
Kaestneriella, either K. fumosa or K. tenebrosa. Peripsocidae.

 
Sadly, I do not have Mockfords Book!
I wish I did. I wish it were easier to learn this kind of material. Sometimes I wonder if I am the first or the last person to encounter a seldom seen Psocid. And I always regret not understanding an organism's niche. I might have a side view of the abdomen. I will check later.

Interesting ...
I really need a side view. Looks somewhat like Peripsocidae, but the head is quite broad. The pale spot along the hind margin of the forewing is a puzzle. Can't get it to family from this image. These 2 are separated (in female) on basis of subgenital plate. Do you have Mockford's book?
