It was first described as a genus without a species in 1857, before being officially described as a proper species in 1860. Some authorities have placed it as a species of the modern genus Chanos, but further studies have affirmed it as being a distinct genus. It is thought to be phylogenetically intermediate between Parachanos and Dastilbe.^[3][4][5]
