The Independence Valley tui chub (Siphateles bicolor isolata) is a subspecies of tui chub endemic to the drainage of the Independence Valley in Elko County, northern Nevada.
Described as "abundant" when first collected and identified in 1965, it was considered extinct within less than a decade due to the introduction of sunfish, bass, and carp to the previously isolated watershed. However, it had been rediscovered by the year 2000, although it remains highly threatened. [1]

The Owens tui chub was described in 1973 as a subspecies of tui chub endemic to the Owens River Basin in Eastern California, United States. The Owens tui chub is distinguished from its closest relative, the Lahontan tui chub, by scales with a weakly developed or absent basal shield, 13 to 29 lateral and apical radii, also by the structure of its pharyngeal arches, the number of anal fin rays, 10 to 14 gill rakers, and 52 to 58 lateral line scales. Dorsal and lateral coloration varies from bronze to dusky green, grading to silver or white on the belly. It may reach a total length of 30 centimetres (12 in). Owens tui chub are believed to be derived from Lahontan Basin tui chub that entered the Owens Basin from the north during the Pleistocene Epoch.
