Abstract: We carried out a field work during three consecutive nights of each month in an annual cycle. Two Shannon traps with protected human bait were used from 17 to 22 hours per night. In total, 3,637 mosquitoes of 26 species were captured. Of which Aedes brelandi, Culex corniger and Sabethes chloropterus are new records. These findings are of medical and biogeographic importance, since Sabethes chloropterus is the vector of yellow fever in the Neotropics.
