I don't want to trick the players into thinking one thing while having a different thing down in the rules. I want it to be obvious from the beginning that these creatures who fill the same combat and economic role in my fantasy game as Dwarves (industrious producers of goods, vast cavern builders, magic immune, martial prowess, ect), follow completely different social systems and interact completely differently with the world.

I was curious if anyone had experience for how much I would need to change to avoid player assumptions. Would a different name be enough? Do I need to change the physical appearance as well? What about entirely different physiology, like 3 noses and a mouth on each hand? The players won't know everything about their society that I know, and I want to make sure that "I don't know yet." is the answer rather than "Well, most dwarves like gold, these ones probably do too."

Saying "Well I never said thesedwarves like gold, so you all die/lose money/other bad thing." Is a little too misleading as a DM.
