The species grow as terrestrial plants usually in paramo and subparamo, but there are also reports of populations in high montane forest. In this paper the complete enumeration of the six Bolivian representatives of the orchid genus Pterichis sect. Pterichis is presented.A total of four new species are described and one new record, P. aragogiana, for the country is reported. An updated key to the species of the nominal section of Pterichis from Bolivia is presented.
