"Hispanics", if often talked about, actually only means "people from South America", not people from the Mediterranean area. And this, again, is an artificial term from the US... As someone told me around here, people in South America from one nation also don't want to be thrown together in the same pot from other particular nations there. Just - just as Germans don't want to be thrown together with Frenchmen, Poles, Hungarians or people from Belarus.
So... what of a nonsense is all that stuff.

Btw, taking a look at East Asia - Japanese, Chinese and people from the Philippines also don't look the same, except maybe that they got slitted eyes as a body feature.
Sure nobody from Indonesia or so would see himself linked with sub-Saharan Africans just because they have a pretty dark skin color from living in an area around the earth's equator.
Africans would be the same; they don't even regard themselves as "one race, one people" inside all of Africa itself.
