Austral Heoda species H. atacama Johnson and Miller, H. nivea, H. shapiroi and H. suprema (all Johnson, Miller and Herrera) and H. wagenknechti (Ureta) are figured in color and their known distributions elaborated from historical and recently acquired material. A remarkably patterned new species, H. erani, is described from a narrow belt of Puna vegetation in Tarapaca, Chile. The new species' restricted biotope reemphasizes the diversity of high Andean Lycaenidae known only from habitats of extremely limited distribution. Entomologists sampling depauperate high montane and austral biomes should look for species of this genus; species of Heoda are currently known from Patagonia north in the high Andes to Colombia and new species have recently been discovered in Colombia and Ecuador. The Puna vegetation belt in northern Chile harbors six known endemic species of lycaenid butterflies; three others are known from restricted mesic quebradas within the lowland absolute desert. Plant diversity, percentage of plant cover and number of species of butterflies are directly related.
