At least here in some parts of Latin America, with apologies, you’re wrong. I buy them regularly when they’re in season, and they are chayotes or mirliton, and here they’re called papas del aire.

If you look at the Spanish entry for the chayote, you’ll see papa del aire listed as one of the alternative names for it. https://es.wikipedia.org/wiki/Sechium_edule

It even has the chayote page as the redirect for the term: “«Papa del aire» redirige aquí. Para otras acepciones, véase Dioscorea bulbifera.”

Even a quick Google search would have revealed this: https://www.google.com/search?q=%22papa+del+aire%22&oq=%22papa+del+aire%22
