Leaf litter trogiid with broken antennae? - Lepinotus reticulatus

Presidio, El Polin Springs, San Francisco County, California, USA
January 25, 2023
Size: ca 1 mm

I extracted this little barklouse from Quercus agrifolia leaf litter using a Tullgren funnel. It has a three-segmented tarsus, seems to have broken antennae (?), lacks a preapical tooth on the claw as best I can tell, and also seems to have a sensillum on the second maxillary palp segment. I think it is probably a trogiid?

Moved from Barklice, Booklice, and Parasitic Lice.

Are those very small wing pads ...

on the second thoracic segment?

… Diane Young, 12 February, 2023 - 7:37pm

I noticed those -

they look like they could be tiny wing "buttons"? I can try to get a high power view of them if it's critical, let me know... thanks!

… Ken Schneider, 12 February, 2023 - 7:40pm

Unless you can find a trait to the contrary ...

this is L reticulatus that has lost both forewings.

… Diane Young, 12 February, 2023 - 7:43pm

Aha -

thanks Diane - that would make sense, I think. Much appreciated!
