Species Richness and Distribution of Sphaeriidae Surveyed with Environmental DNA Metabarcoding

“…Sphaeriidae contains two subfamilies. The Euperinae Heard, 1965, contains 33 species in 2 genera distributed throughout the Americas and the Afrotropics (Graf and Cummings 2023) and includes the invasive Eupera cubensis (Prime, 1865), which occurs in the Illinois River, USA, drainage near the Laurentian Great Lakes (Sneen et al 2009). The Sphaeriinae Deshayes (1820) is widespread and species-rich.…”
