 Due to the apparent rarity of the species no type specimen was collected, instead feathers from the mist net, photographs, recordings and notes were used as the holotype.The International Code of Zoological Nomenclature does not allow for new species to be described without the collection of type specimens, but this provision was circumvented in this case by the collection of feathers (the Code allows for "any part of an animal" to be treated as a type specimen; Art.72.5.1).
