Carpenter bee

This looks like a carpenter bee from the genus Xylocopa and could probably be a specimen of Xylocopa mordax, known locally as 'abejorro carpintero'. If someone is well versed with this type of bee or is able to provide a more accurate identification, please let me know in the comments. I had never seen this before in my backyard where I found it, just laying in the grass, even though I spend meaningful time there every day. Yet, I believe I have seen these bees elsewhere, as the Xylocopa genus is well represented in the island of Puerto Rico and throughout the Greater Antilles. The insect remained unconcerned as I gradually approached, allowing me to get as close as half a meter in order to obtain this close-up. As I withdrew after the photo, the insect just stayed there like nothing happened.
