Corbicula, a “hyper-invasive alien” with great biofouling capabilities, was first recorded in North America in 1924 in British Columbia and breached the Continental Divide in the late 1950s. Since then, it has spread throughout the continent. Corbicula taxonomy is muddled and unclear, as is the number of species that have become established. Literature reports vary from an invasion of but a single species to invasions of multiple species. The Midwest has long been recognized as having only Corbicula fluminea. However, in 2008, a tentative second species, Corbicula largilllierti, began appearing in navigable rivers. A potential third Corbulid species was discovered while sampling the Illinois River in 2015, and was collected in conjunction with C. fluminea and C. largillierti. It is currently unknown in North America, and we have no information for what the species is or its potential impact on aquatic ecosystems. In collaboration with the University of Michigan - Museum of Zoology, genomic and morphometric assessments are being employed to confirm the identity of this undocumented Corbulid and also that of C. largillierti.
