Abstract
The spider genus Stemmops O. Pickard-Cambridge, 1894, currently comprises 22 described species. Spiders of this genus are mainly known from the Neotropical Region, but are poorly studied in Brazil. In this paper five new species of Brazilian Stemmops are described: Stemmops murici new species; Stemmops carauari new species; Stemmops carajas new species; Stemmops pains new species, and Stemmops guapiacu new species. Additionally, new records from Brazil are provided for Stemmops carius Marques & Buckup, 1996 from state of São Paulo; Stemmops belavista Marques & Buckup, 1996 from Mato Grosso do Sul; and Stemmops vicosa Levi, 1964 from Alagoas. The species Stemmops servus Levi, 1964 (known from Panama) is recorded for the first time in Brazil from states of Amazonas, Paraíba, Alagoas, Minas Gerais, Espírito Santo and Rio de Janeiro.
