“…(1%-2%) are within the intraspecific distance thresholds already reported in studies of other Simuliidae species (e.g., Hamada et al, 2010;Hernández-Triana et al, 2012;Nascimento et al, 2016Nascimento et al, , 2020Nascimento et al, , 2021Pramual & Nanork, 2012;Rivera & Currie, 2009). The larger amplitude of intraspecific distance observed in S. oyapockense s.l.…”

“…The hypothesis of cryptic diversity in this group of taxa may be reinforced by the observed distance between S. siolii and S. tergospinosum , two morphologically similar species in the Amazonicum group (Table 2). The genetic distance between these species and the others was similar to those observed between species in the same subgenus of Simuliidae (e.g., Nascimento et al, 2018, 2021).…”

“…Simuliidae has medical and veterinary importance because most species have females with hematophagous habits. This family is known for harbouring many cryptic species that are normally discovered by analysis of polytene chromosomes (e.g., Adler et al, 2010;Nascimento et al, 2018;Post et al, 2007) and by molecular analysis (e.g., Hamada et al, 2010;Nascimento et al, 2020Nascimento et al, , 2021. Distinguishing these species in epidemiological studies and vector-control programmes is important because different species in a complex may exhibit differences in biology, ecology, vector competence, and response to control measures.…”

Problems related to the identity of Simuliidae species are impediments to effective disease control in Amazonia. Some of these species, such as Simulium oyapockense Floch & Abonnenc, 1946 (Diptera: Simuliidae), are vectors of the organisms that cause onchocerciasis and mansonellosis diseases. This blackfly species has a wide distribution in South America, and it is suspected of being a complex of cryptic species. The aim of this study is to characterize the nominal species S. oyapockense using partial COI gene sequences. Seven populations of S. oyapockense (morphologically identified) were analysed, including one from its type-locality. The other six populations were collected in Brazil and in Argentina. A taxon collected in Amazonas state, Brazil, with adults similar to S. oyapockense but with distinct pupae, was also included in the analysis (Simulium 'S').The nominal species S. oyapockense is circumscribed, and its geographical distribution is restricted to areas north of the Amazon River. Populations of S. oyapockense s.l. collected south of the Amazon River comprise a species complex that needs to be evaluated using integrative taxonomy. Simulium 'S' represents a species with unique morphological and molecular characteristics. Distinguishing cryptic species is a prerequisite for reducing the taxonomic impediment, especially in medically important taxa.
