Taxonomy
Chamberlin and Jones (1929) listed Fluminicola seminalis and Fuminicola fuscus as occurring in Utah. Hershler and Frest (1996) restricted F. seminalis to the Sacramento River basin of California and F. fusca to the Columbia River system of the Pacific Northwest; they restricted F. coloradoensis to the Green River drainage and suggested that populations in the Bonneville Basin potentially represented an unrecognized species. Hershler (n.d.) later believed Fluminicola collected in the Bonneville Basin to be a new, undescribed species. However, Hershler (1999) subsequently treated this material as F. coloradoensis and referred early Utah records of F. fuscus to this species as well. Curiously F. seminalis was not included in the list of synonyms, although Utah records of this species are presumably referrable to F. coloradoensis.
