Thanks David! So to make sure I'm interpreting this correctly, the character separating this species from Bactromantis mexicana is that the front and back sections of the pronotum are about equal in length for this one, while in Bactro the front section is roughly twice as long as the back?

plus Oligonicella are quite a bit stockier in build. Seems both are in Hidalgo County, I finally found a published reference to Bactromantis mexicana being in Texas (from Brownsville), so will be moving all of those to the species page.

I had a reference to that some time ago, but not a published one. It was an unpublished dissertation that Mike Quinn located and xeroxed for me, by Raymond Neck. "Invertebrates of the Lower Rio Grande Valley of Texas with Special Reference to the Southmost, Cameron County, Area"

It might be very useful. Maybe I can find a copy.
Thanks

This is where I got my copy:

Or, Neck worked for Texas Parks and Wildlife, somebody there might know how to track down either the man or his work...

I first thought this guy's wings covered his abdomen and ruled out Oligonicella. But looking more closely now, maybe it does peek out past the wings after all... Thanks!

Hi Joshua. Male of this species can have wings all the way cover up the abdomen. But not Thesprotia graminis
