The Mexican dace (Evarra bustamantei), or Mexican chub, is an extinct species of ray-finned fish in the Cyprinidae family. It was found only in Mexico, in the canals and streams of the Valley of Mexico.[2] It is estimated to have become extinct circa 1983.[3] The extinction of this species coincided with the drying of water bodies in the valley. This drying was a result of the increasing demands placed on the water resources of the valley by agriculture, as well as by the growth of Mexico City and it's suburbs.[2]
