Chinchaysuyu gen. nov. is described as a new monotypic Theraphosidae genus from northern Peru, with distinct genitalic morphology. Males of Chinchaysuyu gen. nov. differ from all known species by having a palpal bulb organ with many conspicuous keels extending towards the subtegulum. Females differ by having two pairs of short and hyper-sclerotized receptacles. This new genus is described and illustrated on the basis of the type species Chinchaysuyu spinosa sp. nov. and their morphological affinities and its phylogenetic position are analyzed and discussed.
