Abstract: Corixoidea and Notonectidae are the two most speciose groups of Nepomorpha (Insecta: Hemiptera: Heteroptera). They live in the water column of fresh and brackish water bodies. In Brazil, there are records of 46 species of Corixidae and Micronectidae (Corixoidea), and 58 species of Notonectidae. Of these, 35 species have been previously recorded from the state of Par, in the northern portion of the country. However, large sampling gaps exist in the state, especially in its western portion. Here, we report the results of field work performed from 2019 through 2024 in 12 municipalities within this area, together with an annotated list and identification keys to species occurring in Par. In total, four genera and 11 species of Corixoidea, and three genera and 26 species of Notonectidae, are known from Par. Our new data include the first records from the state of Buenoa deplanatylus Barbosa & Nessimian, 2013 and Martarega williamsi Truxal, 1949, increasing the local richness of Notonectidae by 8%. Finally, B. konta Nieser & Pelli, 1994, B. tarsalis Truxal, 1953, B. tibialis Truxal, 1957, B. truxali Nieser, 1968, B. unguis Truxal, 1953, and Notonecta pulchra Hungerford, 1926 are recorded for the first time from western Par.
