This species has already been figured in the Monograph—the male as O. leucaspis, the female as A. castaneiventris.
It has been thought better to take advantage of the opportunity of re-figuring it along with the other two species of the genus.
Like O. cinereicauda, it has a white throat, but may be easily distinguished from that species by its black tail.
At present it is only known from Panama, where it has been found on the Volcan de Chiriqui. In Costa Rica O. cinereicauda takes its place.
