But I've noticed many of your comments (good and bad) and as latinoamerican I'm grateful for it.
There are many great bands which you mention:
At north, we don't forget interesting mexican black metal bands like Funereal Moon, Bastardi, Ereshkigal, anybody said Xibalba? Morbosidad was born here, but dwell in USA.
Mexico exports good black metal stuff to the world.
Inquisition, well, (also as Morbosidad) they dwell in USA but they arose in Colombia
Utuk Xul, Nebiros, Maleficarum also from this country. I know you've listened and like them, I see in some of my uploads at least. Obviously not only Colombia has great bands.
Bolivia: Bestial Holocaust, Lágrima Santa, Sirion, Xerbeth.
Ecuador: Nihil Domination (rules!), Legión, Grimorium Verum.
Perú: Hadez, Goat Semen, Torment, Levifer (OMG!
)Brazil: hell! What we can say about blacker hordes from Brazil? I'll mention just one: Sarcofago.
At the final of the continent, Chile and Argentina, two generators countries of evil black metal, you know!
For example: Hetroertzen and Grima Morstua (respectively) fabulous bands representing these countries.
From Central America:
Guatemala: Abyssum and Noctis Invocat
My land: Thy Funeral Judas and Ah Ciliz maybe
Of course! Morbid Funeral from Costa Rica, I'd like to see them in live soon!
Did you mention L.A. black metal with NS ideology?
Exekratorio from Bolivia, Uriburu and Viento Patagónico from Argentina, Hastur from Colombia, Evil and (maybe) Ravendark's Monarchal Canticle from Brazil and Comando de Exterminio from Mexico (this band I've not listened it yet)
Latinoamerican black metal for the whole world
