There's no tribal nation, because the tribes haven't united. When the tribe gathers power, it will be assimilated by another culture, or it conquers it. Examples:
Horse Tribe -> LA Tien Barbarian Kings
Toad Tribe -> LA Mictlan
Jade Amazons -> EA Sauromatia
Jaguar and Lion tribe are not-yet-nation versions of EA Mictlan and MA Machaka
Bear Tribe/Barbarians - not really any spesific nation, but they could fulfill the role of two-handed weapon wielder available in most human nations. I mean, MA, Ulm axemen, Marignon twohanders, Man Wardens, Vanheim Skinshifters, Mictlan Moon Warriors - many choices.
Similarly, Deer Tribe isn't adopted into any spesific nation, although MA Eriu units bear some resemblance, what with swords being rare, javelins common and lack of bows.
Amazons don't have their own nation, but as mentioned above, EA Sauromatia has adopted local Jade Amazons.
I'm not sure if this answers your question, but here goes any way.
