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.

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