Hello Rui,

try Mesopsocus genus. I have documented Mesopsocus immunis but i forget how to separate psocids. I know that i depend upon the barkfly recording website:
https://www.brc.ac.uk/schemes/barkfly/key/A.htm

Best wishes,
John

Hello Rui,

I've looked at my photos of M. immunis and it looks very similar, so i do believe that it is of the Mesopsocus genus. I notice that the immunis has striped eyes. The eyes of your specimen lacks a stripe. I don't know if this stripe is unique to immunis or not. I also do not know if it is a male/female thing. Also considering that your specimen is dead. Perhaps a lifeless species loses the stripe?

I can only suggest that you view the genitalia at the end of the abdomen on the underside via microscope. Carefully compare the genitalia to the photos of the species shown at the barkfly site:
https://www.brc.ac.uk/schemes/barkfly/key/A1-B-C2-D20.htm

if genitalia matches one of those three, then voila! otherwise, you will need to consult an expert because Portugal may have more species.

Best wishes,
John

Hi John,

I checked the wing venation and everything matches Mesopsocus. The genitalia is too small for my microscope, so I'll leave it as Mesopsocus sp.
Thanks for all your help!

Hi Rui,

I wish that i had more material/literature to help you. At least you have a genus.

Best wishes,
John
