Geographic location of the bug: Southern Nicoya Peninsula

Can you identify this bug?
I took these pictures a couple of days ago in a house near Santa Teresa.
It looks a bit like a Haemodiasma Tessellata but the body is flatter and the shape of the head looks different. It has very long, thin antennae, approx twice the length of the body, which are not fully visible in the pictures.
Thanks a lot!
How you want your letter signed: Matteo
We agree that your individual does resemble a Moss Mimic Katydid, Haemodiasma tessellata, and it also resembles the Panama Sylvan Katydid, Acanthodis curvidens. We will attempt to contact Katydid expert Piotr Naskrecki to see if he can provide a species identification.
Piotr Naskrecki provides the identification.
Happy New Year to you, too! This is Acanthodis curvidens. Haeodiasma tessellata has a stouter body and the strongly curved spines (“curvidens”) on the hind femur are a giveaway.

It is cool to see Piotr, who I already knew from WTB? on Netflix “72 Dangerous Animals: Latin America”!
Thanks for letting us know about Piotr’s appearance on Netflix.
