ZooKeys 925: 1–54.https://doi.org/10.3897/ zookeys.925.39691 Abstract The systematics of sitticine jumping spiders is reviewed, with a focus on the Palearctic and Nearctic re- gions, in order to revise their generic classification, clarify the species of one region (Canada), and study their chromosomes. A genome-wide molecular phylogeny of 23 sitticine species, using more than 700 loci from the arachnid Ultra-Conserved Element (UCE) probeset, confirms the Neotropical origins of sitticines, whose basal divergence separates the new subtribe Aillutticina (a group of five Neotropical genera) from the subtribe Sitticina (five genera of Eurasia and the Americas).
