Mexican walkingstick
This is Sermyle mexicana (Saussure). Those horns are pretty astounding but Helfer (1987) and Arment (2006) really only mention the middle femur and fifth abdominal segment conspicuously lobed as distinctive characters. I guess they didn't want people to confuse it with the horns found in some of the Diapheromera. Our single specimen in the A&M collection has these horns. In the US it's found in the Brownsville area and only the females are known (it could be parthenogenic).

Ah-HA!
I (obviously) thought that might be it. Yes, very curious why the little "Mickey Mouse ears" aren't used as a clue :-) Thank you, Paul.
