The male of Aillutticus rotundus Galiano, 1987 is described for the first time and new records are presented from the states of Acre, Mato Grosso do Sul and São Paulo, Brazil. In addition, five new species of this genus are described from Brazil: A. knysakae sp. nov. from the states of Minas Gerais, Piauí and Tocantins, A. montanus sp. nov. from the state of Minas Gerais, A. raizeri sp. nov. from the state of Mato Grosso do Sul, A. soteropolitano sp. nov. from the state of Bahia, and A. viripotens sp. nov. from the states of Rondônia and Tocantins.

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).

  • Araneae, Salticidae)
    Three new genera of jumping spider from Brazil (Araneae, Salticidae) Gustavo R. S. Ruiz 1, 2 & Antonio D. Brescovit 1 1 Laboratório de Artrópodes, Instituto Butantan. Avenida Vital Brazil 1500, 05503-900 São Paulo, São Paulo, Brasil. 2 Departamento de Zoologia, Instituto de Biociências, Universidade de São Paulo. Rua do Matão, Travessa 14, 101, 05508-080 São Paulo, São Paulo, Brasil. E-mail: [email protected], [email protected] ABSTRACT. Nosferattus gen. nov.., Capeta gen. nov. and Amatorculus gen. nov. are proposed from North and North- eastern Brazil. Due to the absence of teeth on the retromargin of the chelicerae, these genera are included within the Sitticinae, and are probably related to the genus Aillutticus Galiano, 1987, with which they share a high, broad carapace, rounded laterally behind the posterior lateral eyes, and the cephalic region slightly convex. Nosferattus is proposed to include five species: the type species Nosferattus discus sp. nov. and Nosferattus ciliatus sp. nov. from Maranhão, Nosferattus aegis sp. nov. from Tocantins, Nosferattus occultus sp. nov. from Maranhão and Ceará, and Nosferattus palmatus sp. nov. from Sergipe. Capeta and Amatorculus are both monotypic and are proposed to include Capeta tridens sp. nov.., from Bahia, and Amatorculus stygius sp. nov.., from Distrito Federal and São Paulo, respectively. KEY WORDS. Amycoida, neotropical, Sitticinae, systematics, taxonomy. RESUMO. Três gêneros novos de aranha papa-mosca do Brasil (Araneaeaneae, Salticidae). Nosferattus gen. nov.., Capeta gen. nov. e Amatorculus gen. nov. são propostos para o norte e nordeste do Brasil. Devido à ausência de dentes na retromargem das quelíceras, estes gêneros são incluídos entre os Sitticinae, e provavelmente estão relacionados ao gênero Aillutticus Galiano, 1987, com o qual compartilham uma carapaça alta e larga, arredonda- da lateralmente atrás dos olhos laterais posteriores, e a região cefálica levemente convexa.
