Unknown Bark Louse - Archipsocus

Unknown Bark Louse - Archipsocus
Naples , Collier County, Florida, USA
December 19, 2014
Size: 1.5
This bark louse was living in leaf litter under a citrus tree in an abandoned citrus grove that has evolved into cabbage palm/ oak hammock when it was extracted from the leaf litter using a Berlese funnel.


This one is not Ectopsocus
it is an Archipsocus sp. Mockford says.

Just goes to show that psocids are tricky to ID without microscopy. Note that the compound eyes on your specimen are small and set back pretty far towards the back of the head.

Diane, thanks
for your help with this one. Please thank Dr. Mockford for me too. Do I need better detailed photographs for a species ID?


This one looks very interestng.
It could be Ectopsocus richardsi . Mockford will need to see this one to confirm.

Thanks so much.
Do you want me to include an enlargement of the wing?

Not necessary
I will forward a link to Dr. Mockford.

you so much!
