The Catasticta poujadei group, within the subgenus Hesperochoia Reissinger, is revised. Two new species, C. copernicus Pyrcz & Fhraeus sp. nov., and C. buszkoi Boyer & Pyrcz sp. nov. occurring near the timberline in Junn and Apurmac are described. Catasticta eximia Rber is reinstated as a species separate from C. poujadei, and a new subspecies, C. eximia tapuna ssp. nov., is described. The affinities of the species of the C. poujadei group are evaluated based on COI barcodes. Their distribution and habitats are described.
