Resumen
The male, female, pupa and larva of Simulium litobranchium n. sp. are described and illustrated. This new
species has 12 gill filaments, as do S. duodenicornium Pepinelli, Hamada & Trivinho-Strixino, S. guianense
Wise, S. hirtipupa Lutz, S. perplexum Shelley, Maia-Herzog, Lunas Dias & Couch and S. scutistriatum Lutz,
but it can be distinguished from these other species by a combination of characters observed at the pupal and
adult stages. DNA barcoding showed that Simulium litobranchium n. sp. exhibits more than 4% nucleotide
divergence in cytochrome oxidase I from three other closely related species in the Neotropical subgenus S.
(Thyrsopelma). The new species was collected in the Brazilian states of Goiás and Minas Gerais and inhabits
rivers 30–40 m in width in the Paraná River hydrographic basin. Females were not observed engaging in
anthropophilic behavior.
