Colombia does not have a big selection of local varieties, I looked over some Spanish language documents, and believe the one you have could be the Colombian "Manzano" variety. shape and color look about right. not sure if the Colombian manzano is the same as the Mexican manzano, I do not think they are the same, the Colombian manzano is described as being around 300 grams, and I believe the Mexican one is a lot bigger, if I am not mistaken.
Manzano in Spanish is "Apple" just in case you did not know.
