Paposoa laeta is the only species of the monotypic genus Paposoa in the family Amaryllidaceae endemic to northern and central Chile.

The inflorescence with a hollow, 10–30 cm long, and 2–4 mm wide scape bears 1–7 violet to purple, zygomorphic flowers. The flowers have 6 tepals. The androecium consists of 6 stamens. The gynoecium consists of 3 carpels. The trilocular capsule fruit bears flat, shiny, black seeds.
The chromosome count is 2n = 16.
It was described as Rhodophiala laeta Phil. by Rodolfo Amando Philippi in 1860. A new genus Eremolirion Nic.García was described by Nicolás García Berguecio in 2019, but due to confusion with the similarly named Eremiolirion J.C.Manning & F.Forest (Tecophilaeaceae), a new genus Paposoa Nic.García and species Paposoa laeta (Phil.) Nic.García was required and published by García in 2020. Within the tribe Hippeastreae, it is placed in the subtribe Traubiinae.
The generic name Paposoa refers to Paposo, Chile. The specific epithet laeta means bright,
It occurs in the Atacama and Antofagasta regions, where it is found in desert and desert fog oases (Lomas).
