This paper provides a comprehensive checklist of Nepomorpha and Gerromorpha aquatic hemipterans distributed in Colorado, including species recorded in the literature, specimen records in the C.P. Gillette Museum of Arthropod Diversity and the Denver Museum of Nature and Science, and GBIF and SCAN online databases. Illustrations of all genera occurring in Colorado are provided to facilitate future researchers in identifying these species. This study registered 77 species and subspecies of Nepomorpha and Gerromorpha in Colorado, including 13 families and 30 genera.
Here we report 11 new species and subspecies state records (Belostoma bakeri Montandon, 1913; Corisella edulis Champion, 1901; Neocorixa snowi Hungerford, 1925; Sigara bicoloripennis (Walley, 1936); Sigara lineata (Forster, 1771); Sigara trilineata (Provancher, 1972); Trichocorixa verticalis verticalis (Fieber, 1851); Hebrus comatus Drake & Harris, 1943; Hydrometra martini Kirkaldy, 1900; Mesovelia mulsanti White, 1879), including one species of the genus Callicorixa that has not been formally named or published. These new records can help future researchers identify aquatic hemipterans in Colorado, thereby furthering the knowledge of the relationship between aquatic hemipterans and water quality and ecology.
