The Mexican dace (Evarra bustamantei), or Mexican chub, is an extinct species of ray-finned fish in the family Cyprinidae.

[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 its suburbs.
