Lazy me...
At first glance, I apparently didn't look at the full-size images available to me as Editor. From there, I can see two important features: 1) the cercal "thumb" is way too narrow and pointy for emarginata and 2) the emargination of the subgenital plate (barely visible in the caudal view) is U-shaped (as opposed to V-shaped in emarginata). Both these point to D. castanea. Chestnut back of the male fits this species too.

Moved from Short-wing Katydids.

Thank You for the ID and info
Thank You for the ID and information. I obviously do not pay close enough attention to this group as I always see them and thought they were the same. I will pay more attention on my next encounter.

Dichopetala male
In this area in southern Texas, this could be 4 potential species (emarginata, catinata, gladiator, and castanea). It's not catinata by the male cerci. Beyond that, it somewhat resembles castanea, but I suppose emarginata is also a legitimate possibility. Need a cleaner view of the cerci and/or subgenital plate to be sure.

Moved from ID Request.
