But D&D races aren't all that much like mythological races, or Tolkien races, or 1960s science fiction/fantasy races, or 1980s gamefic races, or contemporary fantasy races. They're a blend of all of those with weird random stuff thrown in, and that's how they've been in every edition of the game. Calling it traditional versus modern or mythological versus fictional is drawing an arbitrary distinction that doesn't correspond very well to the actual material. That's what I was trying to say, that there is no "context of mythology and mythological origins" here, except in a superficial sense. And at that superficial level, Merlin + faun = tiefling, or close enough as to not matter.
But Merlin wasn't a faun.
The way I see it, each of the D&D races has a core identity, defined by appearance and concept, which goes something like this:
Humans: Humans.
Elves: Forest-dwelling, graceful, good-looking guys.
Dwarves: Short guys with an affinity for earth, stone, and metalworking.
Halflings: Sneaky little guys.
Eladrin: Good-looking magic guys.
Tieflings: Devil-spawn with horns and tails.
Dragonborn: Scaly reptile-guys with wings.
The exact details vary, of course, but that's inevitable--even if you were sticking strictly to the mythological roots of each race, there are a hundred variations on elves and dwarves. The thing is that the elf identity matches pretty well with the ljosalfar (though perhaps the fairies of British legend would be a better match), and the dwarven identity matches pretty well with the dvergar. You can point to the dvergar and say, "That there is a dwarf."
But the tiefling identity doesn't match with anything; bits of it match with this, and other bits with that, but as far as I know, there's nothing that you can point to in mythology and say, "That there is a tiefling."

Eh. Since I haven't seen anything saying that Tieflings horns and tails have any game mechanics effect, I'd say that's purely an art direction decision. If you don't want them to have horns and tails in your campaign, they don't.
This is a debate about fluff. I don't see what mechanics have to do with anything. I can slap the tiefling mechanics on giant anthropomorphic weasels; so what?
