Can you help me find the identity of this cricket found in central Peru?

Hi again Peter,
This is not a cricket, but rather, it is a Katydid in the family Tettigoniidae.  Crickets and Katydids are classified together in the suborder Ensifera, the Long Horned Orthopterans.  We often request assistance with exotic Katydid identifications from entomologist Piotr Naskrecki, however, we suspect he is in the field as he did not respond to our recent emails.  We will write to him to see if he recognizes your Katydid.  We can tell you that she is a female as evidenced by her swordlike ovipositor.

Hi Daniel,
Thank you.
On this side of the Atlantic the Tettigoniidae are known as Bush-crickets and the term “katydid” is alien to us, hence my (imprecise) use of “cricket”. I look forward to hearing what your expert makes of it, and will hold back my other similar queries until he is in contact again.
Best regards,

Hi Daniel,
This is a female of Choeroparnops, most likely C. tuberculatus (Tettigoniidae: Pseudophyllinae: Platyphyllini).

Thank you Daniel. That was quicker than I expected. I have a few more orthopterans to enquire about; I’ll start with the long-horned ones.
All the best,
