The Devils River minnow (Dionda diaboli Hubbs and Brown) is a small fish in the minnow family (Cyprinidae). Its historic range includes Rio Grande tributary streams in Val Verde and Kinney counties, Texas, (Devils River, San Felipe, Sycamore, Pinto, and Las Moras creeks) and several streams in northern Mexico. However, the fish has been eliminated or reduced throughout much of its range. The primary threats to the species include habitat loss and degradation (water quantity and quality) and impacts from non-native species.
