Species range
Only five Utah occurrences of this species are known, these being in Utah County (Ingersoll 1877, Chamberlin and Jones 1929), Sevier County (Chamberlin and Berry 1930), Salt Lake County (Woolstenhulme 1942), Grand County (Henderson 1936), and San Juan County (Henderson 1936).
Habitat
Habitat information for this species in Utah is lacking. However, two of the reported localities are canyons descending west from the Wasatch Mountains (Chamberlin and Jones 1929, Woolstenhulme 1942) and another is a moderately high (approximately 8,000-9,000 ft elevation) location in the central High Plateaus (Chamberlin and Berry 1930). Part of the locality data reported by Woolstenhulme (1942) was "Stepping Stone Spring", which, though this species is terrestrial and would not have been in the spring itself unless it was dead (drift) material, suggests a moist, probably riparian site.
Threats or limiting factors
Threats to this species in Utah are not known but are thought not to be great.
