Argentinia

LDH
Le Droit Humain is active in Argentinia.


AFHR
The Honorable Order of American Co-Masonry is a 1994 split-off of Le Droit Humain USA (see there for more history). Nowadays the order has 29 lodges in four countries: USA, Brazil, Chile and Argentina (Mendoza). Lodges in Canada and Paraguay are in development.


EasternOrder
Eastern Order of International co-Masonry was founded in 2002 in Adyar, India as a split-off of Le Droit Humain. Their website says that:

The Eastern Order of International Co-Freemasonry currently has lodges in Argentina, Brazil, Costa Rica, India, New Zealand, Puerto Rico, Spain, United States, Australia, and South Africa. . Others are in the process of forming.


ArgentinaFem
Gran Logia Femenina de Argentina lists 7 lodges on their website.


Memphis
Rite of Memphis-Misraïm is a combination of the Rite of Misraïm that was founded by Cagliostro in 1738 and the Rite of Memphis that was founded by Jacques Etienne Marconis de Nègre in 1838. In 1889 General Garibaldi combined the two the Rite of Memphis-Misraïm.

Nowadays there is an international organisation working in Argentina, Brazil, Chile, Spain, France, Martinique, Mauritius, New Caledonia, Scandinavia, Switzerland, Uruguay, USA, England, Venezuela.
There are other organsations with similar names.

The website does not say that members have to be master Masons in another lodge, so it does not appear to be a system of side/higher degrees. On the other hand, the website does not say anything about the “blue” grades of Entered Apprentice, Fellowcraft and Master Mason, so I am not 100% sure.
What the website also does not state specifically, is that Memphis-Misraïm lodges are mixed. It does say however under “conditions for admission” that: “You must have been questioned by several Brothers or sisters” (my emphasis). Cagliostro wanted to admit women, so it sounds like this tradition is still followed.


I am sure there is more mixed and female Freemasonry in Argentinia. Finding more information is a future task. Help is welcome.
