Three new species in the Smicridea (Smicridea) nigripennis species group are described and illustrated based on specimens collected in Serra da Mocidade National Park and Serra do Tepequém in the northern mountain range of Brazilian Amazonia, Roraima State, and in Rio Formosinho located in Cerrado biome of midwestern Brazil, Mato Grosso do Sul State. Smicridea (Smicridea) mocidade Desidério & Rázuri‐Gonzales, sp. nov., Smicridea (Smicridea) santosi Desidério & Rázuri‐Gonzales, sp. nov. and Smicridea (Smicridea) tepequensis Desidério & Rázuri‐Gonzales, sp. nov. can be recognised mainly by the morphology of the phallic apparatus. New distributional records are provided for Smicridea (Smicridea) caatinga Alves et al., 2018, Smicridea (Smicridea) franciscana Rocha et al., 2016, Smicridea (Smicridea) mirnae Almeida & Flint, 2002 and Smicridea (Smicridea) palifera Flint, 1981. Smicridea (Smicridea) cornuta Flint, 1974 is recorded for the first time from Brazil. Additionally, a key to identify males of the 10 species in the Smicridea (Smicridea) nigripennis species group known from Brazil is provided.
