Found at UV lights. What a cool bug! I have heard of these before but never seen one. Seems these are usually found closer to water - I am about 100m from our creek.
Looked through the key in Epler 2006 which hopefully covers Texas spp. - 2 pits on supracoxal lobes of middle leg, 2nd antennal segment about 2.5x length of first.
I did not know what details I was looking for so I got lucky capturing that particular detail on the middle leg.
