I would be grateful for help identifying the insect depicted in the attached picture. It was found inside a residential building (ground floor) at the periphery of Valladolid, a city in Yucatán, Mexico. Unfortunately, I am unable to provide a precise size, but from my recollection, it was about 1-2 cm long. By my (highly uneducated) guess, it seems that it might be an early stage of a member of the Triatominae subfamily, but I would appreciate a more precise/informed identification.
This is a weevil, a beetle in the superfamily Curculionoidea. Most weevils are easily identified by the usually-present elongated snout (or rostrum [Davis (2017)] )
There a number of common home-invading weeviles (e.g., see UMN Extension), including a number of nuisance grain weevils (see my previous Bio.SE post). However, your specimen does not look like any of these....
Your specimen reminds me quit a bit of one of the better known species, the boll weevile (Anthonomus grandis), which is native to Mexico but is typically found in/around cotton fields. (I don't suppose you live near or work with cotton?). Though, your specimen is also larger than the typical 0.3-1.0 cm size of the boll weevil.

Wikipedia states:
Because so many species exist in such diversity, the higher classification of weevils is in a state of flux.
As such (and since your specimen is not one of the common house pest species I'm used to seeing), I'm going to leave my post open ended unless you end up updating with additional details. I think the boll weevil is ultimately unlikely your specimen (though not impossible), but it should serve as a good example to demonstrate this group and a potential jumping-off point for further investigation.
