We found this beetle on the wall od our terrace, what kind is it?
Your beetle reminds us of a North American Prionid known as the Hardwood Stump Borer, Mallodon dasystomus, so we tried to search for Puerto Rican species, and we found a reference on Prioninae of the World to a Puerto Rican species, Nothopleurus maxillosus, formerly known as Mallodon maxillosum. An image of a Brazilian relative, Nothopleurus lobigenis, that we found on Cerambycidae Species looks very similar to your individual. Continued searching brought us to an image on the Worldwide Cerambycidae Photo Gallery that looks very close to your image and it is identified as Hovorodon bituberculatum. We would not rule out Stenodontes exsertus also found on the Worldwide Cerabmycidae Photo Gallery.
