Taxonomic History
- 2026 Allpamayu suyuwixsa Beratz, Ferretti, Chaparro, Ochoa, Allen & West, 2026
- Type species of Allpamayu by original designation, and its only species. The genus is named for Alpamayo, the 5947 m Peruvian peak often called the world's most beautiful mountain for the symmetry of the flutes on its face — which the authors saw echoed in the stripes on this spider's abdomen. Allpamayu is the Quechua form of the mountain's name.
