Distribution.—This group consists of one Chilean and five Argentinian endemics and one further species which inhabits both countries. The two species in Chile are adjacent to the border with Argentina. The total range is from northern Mendoza Province in Argentina to Tarapacá Region, Chile, the latter being a northernmost outlier. Tucumán and Catamarca provinces contain the main centre of diversity.

Etymology: The section epithet Triflabellium is based on the original name given to the group by Becker, referring to the diagnostic style crest consisting of one apical and two lateral flabellate, discrete lobes.
