What's That Bug? does not endorse extermination

What kind of bug is this?
Hello Bugman!
Me and my family went on vacation to the mountains this weekend. The kids found this beautiful specimen while playing in the backyard. I was wondering if you could identify it for us (and maybe point us to more pictures of the same species in the Internet). We live in the Dominican Republic on the Caribbean. This bug was found at 4,000 feet high playing in the grass among the pine trees. Is the color red normal from this area? Is the back horn used to sting? Is this a male or female variety? Where can we find more pics and info on this bug? Cheers,
Alberich

hi Alberich,
We are going to start guessing here. We know that this is a member of the order Orthoptera that contains crickets, grasshoppers and katydids. We believe it is in the suborder Ensifera, the Longhorned Orthopterans. It might be a Shield Backed Katydid in the subfamily Tettigoniinae, or a Spiny Predatory Katydid in the subfamily Subfamily Listroscelidinae, or perhaps some other group found in the tropics but not in the U.S.A. She is a female, as evidenced by her long, swordlike ovipositor. At any rate, she is magnificent. Often it is difficult to get a positive identification on tropical species because of limited information available online. We will post your photo and hopefully get an answer.

Update: (07/03/2008) Katydid IDs from Piotr Naskrecki
Hi,
I have been looking at the page with unidentified katydids (Katydids 2), and thought I could help with some ID’s. From top to bottom they are: Dominican Republic Polyancistrine – Polyancistrus loripes
