Steak cuts - Help with translation to American

I'd be grateful to know the US names for the following Argentian steak cuts (UK names in brackets)

Cuadril (Rump)

Chorizo (Sirloin)

Ancho (Rib-eye)

Lomo (Fillet)

Media Luna de Vachio (Flank )

while the actual primal cuts are a bit different, I think most of those the UK cut and US cut are named similarly. Except we don't usually see rump steaks (sometimes rump roasts), I believe that is what we usually call round.

Here is a diagram (I won't make the image appear in this message, just the link)

I agree that the British and US names correspond well. And it really helps if you can find a similar diagram in Spanish, from Argentina.

I took the notion some years ago that I wanted to cook a Tafelspitz in the style of old Vienna. It was rather hard to figure out just where a Tafelspitz was on a steer, and what American cut I had to buy to get one. But I found a diagram in German (actually I think the Austrian cuts are different from the German cuts) and figured it out.

This link should be useful, as it's specifically Argentinian

This link illustrates the problem, there aren't "Spanish language cuts" -- this is from Chile and I think all the names are different.
