Thanks Diane!
Forgive the novice question, but how do you distinguish between male and female barklice?

Moved from Barklice, Booklice, and Parasitic Lice.

Here goes ...
In many families like Psocidae and Lachesillidae, the males are slimmer and have larger compound eyes. Even in Caeciliusidae, one can tell by the size of the cd. eyes. It's trickier in booklice, Psyllipsocidae and others. In many taxa the phallosome of the male can be seen without dissection. Hope this helps.

OK, thanks Diane!
I'll post this to the information page. Thanks for the help - I'll try to start sexing them from now on!

This is ...
Hyalopsocus striatus, male. It resembles Indiopsocus, but the phallosome is very prominent and different from Indiopsocus (you can see a small part of it in your image). A character of striatus is "cell Cu2 brown before nodulus".
