Abstract

Aquatic insects were collected from Arizona during 2022, and museum specimens and observations posted to online platforms were reviewed to support new records. Notes and records are provided for 8 species of aquatic Coleoptera and Hemiptera. Three species are reported for the first time from the United States in Arizona: Hydaticus rimosus (Dytiscidae), Neobidessus youngi (Dytiscidae), and Rhagovelia ignota (Veliidae). Two additional species are new state records for Arizona: Copelatus debilis (Dytiscidae) and Meridiorhantus calidus (Dytiscidae). Distributional notes are provided for Abedus breviceps (Belostomatidae) and Rhagovelia choreutes (Veliidae). A form of Copelatus distinctus (Dytiscidae) with greatly reduced striae is illustrated.
