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. Nosferattus é proposto para incluir cinco espécies: a espécie-tipo Nosferattus discus sp. nov. e Nosferattus ciliatus sp. nov. do Maranhão, Nosferattus aegis sp. nov. do Tocantins, Nosferattus occultus sp. nov. do Maranhão e do Ceará, e Nosferattus palmatus sp. nov. de Sergipe. Capeta e Amatorculus são ambos monotípicos e são propostos para incluir Capeta tridens sp. nov.., da Bahia, e Amatorculus stygius sp. nov.., do Distrito Federal e de São Paulo, respectivamente. PALAVRAS CHAVE. Amycoida, neotropical, Sitticinae, sistemática, taxonomia.

We have interpreted this in a broad sense, so that all islands from Trinidad to the Bahamas have been included. Furthermore, we have included Bermuda, even though it is well north of the Caribbean region proper, as a more logical extension of the island fauna rather than the continental North American fauna. This was mentioned by Banks (1902b) nearly a century ago. Country or region (e. g., pantropical) records are included for those species which have broader ranges than the Caribbean area. We have not specifically included the islands of the Florida Keys, even though these could legitimately be included in the Caribbean region, because the known fauna is mostly continental. However, when Florida is known as the only continental U.S.A.

Wijesinghe Department of Entomology American Museum of Natural History Central Park West at 79th Street New York, New York 10024 The monumental Histoire Naturelle des Araignées, published in Paris from 1897 to 1901 by Eugene Simon, still remains the only encyclopedic treatment of the spider genera of the world. In this day and age, the fact that the keys and the descriptions are in Latin is an increasingly serious inconvenience. It is hoped that a translation of Simon's keys to the Groupes of the large and systematically difficult family of jumping spiders, the Salticidae, will be a welcome aid to the increasing numbers of workers in that family. While many, though not all, of Simon's groups are admittedly artificial, they still represent the only available general scheme for identification and access to the literature. The features that Simon used in his keys, such as the relative position of the posterior median eyes, the shape of the ocular quadrangle, the curvature of the line of the anterior eyes, the relative lengths of the third and fourth legs, the presence and position of the thoracic groove, and the spination of the legs, to mention a few, still serve for identification and classification.

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).

Eustiromastix spinipes (Taczanowski 1871) is reported for the first time from Colombia. The known distribution of Breda lubomirskii (Taczanowski 1878), Lurio solennis (C. L. Koch 1846), Pachomius dybowskii (Taczanowski 1872), Tanybelus aeneiceps Simon 1902, and Xanthofreya albosignata (F. O. Pickard- Cambridge 1901) is extended to include the Department of Co rdoba. New records are also provided for Helvetia albovittata Simon 1901, Leptofreya ambigua (C. L. Koch 1846), and Scopocira dentichelis Simon 1900. Keywords. Arachnida, jumping spiders, Neotropical, zoogeography Introduction Presently 125 species of salticid spiders, placed in 52 genera, are known from Colombia (WSC 2021; Metzner 2021). For the Department of Cordoba, a total of 22 species have been recorded, distributed in the lower elevations of the northern part of the Department of Cordoba (Bedoya-Roqueme & Lopez- Villada 2020).
