refers to an expression used by the Brazilian gaúcho (people living in Rio Grande do Sul State) which means a horse that has not been castrated. However, for gaúcho’s culture, it is also an adjective used as a synonym for being brave, courageous, fearless and audacious, as is the case here. Because these annual fish have unique adaptations for living in an extreme environment (the pond dries up completely during some months of the year) and have been discovered in a remote and isolated area, we consider the new species ‘bagual’. A name in apposition.
