I don't see much diffrence between the concepts of tribe, meta-ethnicity or ethncity, its all relative, for example if one calls several related groups from the Iberian peninsula an ethnicity then each of this groups will be a tribe, but if one calls it an meta-ethnicity then there groups will be ethnicities. It depend on what brunch of the huge tree you are looking at.

Now I dont understand why you talk about Brasil and mulatos, because they are bio-culturally very different from europeans. Anyway, I'm not sure but I think that about 35 million brasilians might be considered portuguese or at least assimilable because they are of portuguese descent and white.

About the example I gave about occitanians, ok, not the best example, but you get my point.

Regarding the portuguese ethnicity, what is after all an ethnicity? I beleive it's a group of people with a common indentity, a group of people bounded by their similarities, that are more related within themselves that with external people. Various factors enter in the defenition of this similarity, they are of a bio-cultural character, and I use this term because part of the culture of the people derives from biology. The biological diffrences between iberian ethnic groups (excluding basques) are extremely small, even the biological differences between all europeans are not very important, and a person from Braga might be biologically more related to someone in Moskow that with another person from Braga. Thus the cultural differences between white people have almost absolutelly no biological roots. So the Identification of ethnicities must be based in differences such as language, also, considering that each ethnicity as the destiny of becoming more distinct as time evolves and eventually in the distant future there will be biological differences, common descent is also important. This is why I consider Portugal and Galiza an ethnicity (divided if different tribes).

Could you please explain what is common in the ethnicities from the Iberian Peninsula that make them a meta-ethnicity? Tribes and ethnicity if you will...
