I remembered your comment about the thickness of P. sparsus antennae (made elsewhere), and given the limited choice of limnephilids represented in the collecting record for KY, P. sparsus seemed likely. My question: Other than the thickness of the antennae, what might help distinguish between (especially closed-wing) photos of Pseudostenophylax and Ironoquia?

Gonzo - yours is a better memory than mine - I will have to go back and see what I said then. This could indeed be Ironoquia - the hind wing doesn't look quite deep enough. A clear picture of the forewing (or hindwing)venation may resolve the question. At least in NA I believe the origination of vein R2 on the discoidal cell is anterior of the "chord" a greater distance than the tallest height of the discoidal cell for Ironoquia. In Pseudostenophylax, the R2 origination is much closer to the "chord," less than the discoidal height. If you get a good photo of the forewing, or have the specimen in hand it is quite apparent. I have sent Taju a pm for his email and I can send him a figure of the genitalia. I will also send the Ironoquia and he should be able to readily see the difference.
