America/Argentina/Buenos_Aires – Buenos Aires (BA, CF)
America/Argentina/Cordoba – most locations (CD, CC, CR, ER, FO, MN, SF)
America/Argentina/Salta (SA, LP, NQ, RN)
America/Argentina/Jujuy – Jujuy (JY)
America/Argentina/Tucuman – Tucuman (TM)
America/Argentina/Catamarca – Catamarca (CT), Chubut (CH)
America/Argentina/La Rioja – La Rioja (LR)
America/Argentina/San Juan – San Juan (SJ)

I didn't check them all, but some of them are definitely missing. For example "America/Argentina/Santiago_del_Estero".
