Concept Reference: Liu, H.P., Walsh, J. and Hershler, R. 2013. Taxonomic clarification and phylogeography of Fluminicola coloradensis Morrison, a widely ranging western North American pebblesnail. Monographs of the Western North American Naturalist 6(1):87-110.
Concept Reference Code: A13LIU01EHUS
Name Used in Concept Reference: Fluminicola coloradensis
Taxonomic Comments: The genus Fluminicola is in need of revision because genetic analyses show that the genus is paraphyletic (Hershler and Liu 2012).

The taxonomic treatment of Fluminicola coloradoensis Morrison 1940 has undergone several changes since its description (Taylor 1966, Hershler and Frest 1996, Hershler 1999, Frest and Johannes 2000). In an ongoing effort to resolve the taxonomy, Liu et al. (2013) conducted mtDNA analyses, which resulted in the unassigned Snake River basin populations being assigned to F. coloradoensis, as well as the re-assignment of the lower Salmon River (Idaho) populations of Fluminicola fuscus to F. coloradoensis.

Hershler and Frest's (1996), Hershler's (1999), and Liu et al.'s (2013) use of "Fluminicola coloradensis" is an unjustified emendation.

NatureServe Global Conservation Status Factors

Range Extent: 20,000-200,000 square km (about 8000-80,000 square miles)
Range Extent Comments: This species is found in the Upper Green River and Bonneville basin in western Wyoming, Idaho and northeastern Utah. It also extends into the upper Snake River basin and lower Salmon River of Idaho (Liu et al. 2013).

Number of Occurrences: 21 - 300
Number of Occurrences Comments: This species is represented by a moderate number of occurrences (subpopulations). Based on Hershler (1999), about 15-22 sites were estimated as extant in the Upper Green River and Bonneville basins in Wyoming, Idaho and Utah; this estimate excluded vague, subfossil, and overlapping sites. The inclusion of populations from the upper Snake River basin in Idaho greatly increases the total number of occurrences.

Population Size Comments: The total population size is unknown. Stockton et al (2012) notes that in Hagerman Valley (Idaho), they are rather widely distributed and occur at high population densities and Lysne and Pierce (2009) found it abundant in Crystal Creek-Spring Creek in Blaine County, Idaho (both recorded as F. fuscus, but reassigned to F. coloradoensis by Liu et al. 2013).

Overall Threat Impact Comments: Threats have not been assessed, but there is localized habitat degradation in the Bonneville and Upper Green basins (Liu et al. 2013). The upper Snake River basin populations may be affected by fish farming and related activities. Stockton et al. (2012) tested the potential toxicity to Fluminicola fuscus (re-assigned to F. coloradoensis by Liu et al.2013) to the Fluorescein dyes that are used to trace groundwater flows that supply springs used in fish farming and conservation aquaculture operations and found it be minimal.

Short-term Trend Comments: Trend over the past 10 years is difficult to assess given the changes in taxonomy of that have broadened the species concept.
