Etymology

The generic name, meant to be pronounced as "goo-niel-fiah", comes from Wüñelfe, the Mapudungun name for the planet Venus, also seen as a mystic symbol of the flower of the Foye, a sacred tree, and a representation of the Mapuche freedom and untamed spirit. The specific name comes from the Región del Maule of Chile where it was found.
