The Sihuanaba, La Siguanaba, Cigua or Cegua is a supernatural character from Central American folklore though can also be heard in Mexico. It is a shape-changing spirit that typically takes the form of an attractive, long haired woman seen from behind. She lures men away into danger before revealing her face to be that of a horse or, alternatively, a skull.
The Siguanaba and its variants may have been brought to Latin America from Spain during the Colonial Period, used by the colonists as a means of exercising control over the indigenous and mestizo population.
It would be to maintain their language and culture, because they're the type of people who TREASURES their culture, and don't like to change just to fit in. I hope I helped! =D
