Extinct species of fish

Evarra bustamantei Conservation status Extinct (IUCN 3.1)[1] Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Cypriniformes Family: Leuciscidae Genus: †Evarra Species: †E. bustamantei Binomial name †Evarra bustamantei Navarro, 1955

The **Mexican dace** (***Evarra bustamantei***), or **Mexican chub**, is an extinct species of [ray-finned fish](/source/Ray-finned_fish) in the family [Leuciscidae](/source/Leuciscidae). It was found only in [Mexico](/source/Mexico), in the canals and streams of the [Valley of Mexico](/source/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](/source/Mexico_City) and its suburbs.[2]
