Well, the last year in april I went to Oaxaca México and I captured this guys, at first time I thought they was Vieja Regani, but now I know that they are Paratheraps sp. Coatzacoalcos, I caught them in River Almoloya, 2 or 3 km far away from Matias Romero Oaxaca.
I would like to put all my photos of them since I captured them until now that they have been parents.
Here is one of them in my hand
Here a some photos of the habitad
