The jumping spider tribe Thiodinini is revised at generic level: diagnoses are proposed for all valid genera, based on the type species of each genus, and in some cases, on new species herein described. The tribe contains seven genera: Thiodina Simon, 1900; Cyllodania Simon, 1902; Hyetussa Simon, 1902; Atomosphyrus Simon, 1902; Arachnomura Mello-Leitão, 1917, Titanattus Peckham & Peckham, 1885 and the new genus Tartamura gen. nov. The following genera are synonymized: Micalula Strand, 1932 and Bredana Gertsch, 1936 with Hyetussa Simon, 1902; Agelista Simon, 1900 with Titanattus Peckham & Peckham, 1885. With this, the following new combinations are established: Hyetussa longithorax (Petrunkevitch, 1925) comb. nov. (this species with a neotype designation), from Micalula, and Hyetussa complicata (Gertsch, 1936) comb. nov. and Hyetussa alternata (Gertsch, 1936) comb. nov., both from Bredana. A transfer is proposed: Thiodina minuta comb. nov. (from Cyllodania). Twelve new species are described: Arachnomura querandi sp. nov.; Cyllodania trinidad sp. nov.; Cyllodania zoobotanica sp. nov.; Hyetussa sergipe sp. nov.; Hyetussa tremembe sp. nov.; Tartamura agatelin sp. nov.; Tartamura huao sp. nov.; Tartamura metzneri sp. nov.; Thiodina firme sp. nov.; Thiodina perian sp. nov.; Titanattus acanjuba sp. nov. and Titanattus euryphaessa sp. nov. Morphological traits and aspects of the phylogeny are discussed.

Three new species of Kalcerrytus Galiano, 2000 from the state of Pará in the Brazilian Amazon are described: K. amplexus sp. nov. from Parque Nacional da Serra do Pardo, São Félix do Xingu, K. filipi sp. nov. from Reserva Ecológica do Jari, Almeirim, and K. leonardi sp. nov. from Juruti. These increase up to 18 the described species within the genus.

The Hurieae group was created by Simon (1901) and revised by Galiano (1987). This group includes the genera Admesturius Galiano; Atelurius Simon; Hurius Simon; Scoturius Simon and Simonurius Galiano. They are nested within the Neotropical clade Amycoida (Maddison & Hedin 2003), but their phylogenetic relationships among these genera are uncertain.
