Five collecting trips were carried out between 2014 and 2016, when traps baited with fermenting bananas were used. A total of 154 specimens, three genera, and six species were collected of Mesembrinellidae; 196 specimens, three genera, and seven species of Neriidae; 272 specimens, three genera, and six species of Ropalomeridae; and 624 specimens, 22 species and 10 genera of Sarcophagidae. Species accumulation curves for all families except Sarcophagidae demonstrated a strong tendency towards stabilization, showing that sampling efforts were sufficient to record most of the targeted species. Laneela perisi (Mariluis, 1987) (Mesembrinellidae) is a new record for the state of Pará. Among Ropalomeridae, Apophorhynchus amazonensisPrado, 1966, is a new record for Pará. Among Sarcophagidae, Helicobia aurescens (Townsend, 1927) is newly recorded from the Brazilian Amazon, and Ravinia effrenata (Walker, 1861) and Titanogrypa larvicida (Lopes, 1935) are new records for Pará.
