Literature review
The data used in this study were extracted from approximately 200 relevant English and Portuguese articles. A total of 8 families of fleas were reported in this review, and these ectoparasites were present in all the 26 states of Brazil. Some species are widely described in the literature; for this reason, the studies were limited by host or locality descriptions, such as the families Pulicidae and Tungidae. This finding is expected, as species within these families exhibit generalist habits regarding both hosts and habitats [17]. Figure 1 represents the localities of families and subfamilies of fleas in the Brazilian states with the literature records and the new records of this study.
