Seven species belonging the subgenus Nyssorhyncus were found. Anopheles (N.) darlingi, the principal vector of human malaria, was the most abundant (53.1%) followed by A. (N.) evansae (21.0%, A. (N.) triannulatus (17.4%) e A. (N.) nuñeztovari (4.8%). The others, A. (N.) argyritarsis. A. (N.) oswaldoi and A. (N.) rangeli, were less frequently found, representing only 3.7% of the total sample. The anophelines were most frequent in both the extra (51.7%) and peridomiciles (45.7%). The intradomicile was visited by some specimens of the A. (N.) darlingi and A. (N.) evansae (active in both the rain and dry seasons, especially in the former, when the malaria reached high levels of transmission.
