The White River spinedace, Lepidomeda albivallis, is a critically endangered cyprinid fish of Nevada, occurring only in the White River in the southeastern part of the state.

This spindace ranges from green to olive above, a brassy silver on the sides, becoming a silvery white underneath. The sides may also have a pattern of faint sooty patches. dorsal and caudal fins are shades of brown, ranging from olive brown to a pinkish brown; the rays tend to be olive with the membranes between being transparent with a rosy cast. Pectoral fins are yellowish, while the pelvic and anal fins have white rays with red-orange membranes. The dorsal fin has 7 rays, the anal fin has 8 rays, and the pelvic fins usually 7. Size ranges up to 15 cm.

The range is limited to a single cool spring and its overflow area in the upper pluvial White River.
