as far as I know, you don't use the article when Zio or Zia is in the singular form. I believe in the tutorial Sophie said you must use the article when referring to a specific aunt/uncle (like Uncle Peter, rather than "my uncle"), but otherwise the only exceptions I know for using the article are Mamma and Papa, and with plurals.
