ABSTRACT
Female mosquitoes of the genus Sabethes Robineau-Desvoidy, 1827 are implicated in the transmission of several arboviruses, including yellow fever virus. Here, we present an illustrated species identification key for females of the genus Sabethes recorded in Brazil, except Sa. nitidus Theobald, 1901 and Sa. harbachi Nascimento-Pereira, Guimares, Loureno-de-Oliveira & Motta, 2021 as only the males of these species are known. The key is available in dichotomous and interactive formats. An updated list of the Sabethes species of Brazil and new occurrence records for the states of the country are provided. The type localities of four speciesSa. glaucodaemon (Dyar & Shannon, 1925), Sa. amazonicus Gordon & Evans, 1922, Sa. belisarioi Neiva, 1908 and Sa. soperi Lane & Cerqueira, 1942are corrected or restricted.

We discovered the immature stages of Wyeomyia shannoni Lane Cerqueira, 1942, unknown for almost 80 years, and found that they, as well as the adult male, are identical with those previously described for Sabethes (Peytonulus) paradoxus Harbach, 2002. Consequently, the species described by Lane and Cerqueira is here considered a senior synonym of Sa. paradoxus and is transferred to the genus Sabethes, hereafter named Sabethes (Peytonulus) shannoni (Lane Cerqueira, 1942), comb. n. As the name shannoni is preoccupied in the genus Sabethes, the species known as Sabethes (Sabethes) shannoni Cerqueira, 1961 is here renamed Sabethes (Sabethes) cerqueirai Nascimento-Pereira, Neves, Loureno-de-Oliveira Motta, nom. n. We improved the morphological characterization of Sa. (Pey.) shannoni (Lane Cerqueira) by including an illustration of the female genitalia, larval mouthparts and the female genital lobe of the pupa. Finally, we describe and illustrate a new species of Sabethes closely related to Sa. (Pey.) shannoni, named Sabethes (Peytonulus) harbachi Nascimento-Pereira, Guimares, Loureno-de-Oliveira Motta, sp. n.
