I’m pretty sure this is Jatropha sympetala. The trunk texture and bark are like a yellow version of many of the Bursera spp. in this region. Locally the tree is called “Papelillo”, which is the name ascribed to the Bursera as well. The tree grows up to 10 m high with a round(ish) branching canopy. As can be observed in the photo below, the bark peels off the trunk in large, very thin sheets. Deciduous and very drought tolerant.
For those interested, here are some previous posts from this site related to the Euphorbiaceae family.
