There is a publication with a key to Derobrachus by Santos-Silva (2007).
Your specimen is a female. Some species in this genus are impossible to identify from one photograph. It might be D. megacles which is common in some areas of Mexico such as Jalisco.
Was there a male specimen supplied with this female?
I don't see if your specimen has the apex of elytrae spiny ? With this pronotum granulated and antennal joints spiny, it looks like a female of D. procerus...
Derobrachus megacles ???
