Two species in the genus Augastes are recognized, both of which are endemic to montane plateaux in the interior of Brazil. While the Hooded Visorbearer (Augastes lumachella) is restricted to the state of Bahia, the Hyacinth Visorbearer is confined to the state of Minas Gerais in east-central Brazil, and somewhat remarkably it is subdivided into three subspecies. This stunningly beautiful and chunky-bodied hummingbird of xerophytic vegetation on rocky hillsides, known as campo rupestres, is predominantly green above and dark blue below, with a white pectoral band, and brilliant golden green throat and visor. Within its tiny range and in suitable habitat, the Hyacinth Visorbearer is still reasonably common, although BirdLife International currently regards the species as Near Threatened, given some apparent pressures on its habitat. The three subspecies are relatively poorly differentiated and the species might be better treated as monotypic.
