Abstract

Nosferattus gen. nov., Capeta gen. nov. and Amatorculus gen. nov. are proposed from North and Northeastern 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.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, arredondada 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.
