Pahranagat Spinedace (Lepidomeda altivelis)

The Pahranagat Spinedace was described in 1960; the species is known from the outflows of The Ash Spring in the Pahranagat Valley in Nevada, USA, it preferred moderately swift, clear water.

The species was last recorded in 1938 and is now considered extinct; it disappeared most likely due to competition with- and predation by introduced fish- and frog species.
