North America: Amargosa River basin in Nevada and California, USA.
Six subspecies were recognized:
Cyprinodon nevadensis nevadensis, restricted to Saratoga Springs and adjoining lakes, Death Valley National Monument in California;
Cyprinodon nevadensis amargosae, restricted to Amargosa River in California;
Cyprinodon nevadensis calidae, now extinct, in outlets of North and South Tecopa Hot Springs in California;
Cyprinodon nevadensis shoshone , in outlet of Shoshone Springs in California; ,br>
Cyprinodon nevadensis mionectes, in large springs in lower Ash Meadows in Nevada;
Cyprinodon nevadensis pectoralis, in small springs in hills around Devils Hole, upper Ash Meadows in Nevada.
北美洲: 在內華達州與美國加州已知只來自 Amargosa 河流域了。

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Its reproductive strategies differ from many spring-dwelling pupfishes. Cyprinodon n. amargosae is a group spawner. Males do not establish and defend territories as do males of spring-dwelling subspecies. Instead, a reproductive male usually directs a receptive female to the periphery of the group where spawning occurs, although spawning may even take place in the center of the group (www.death-valley.us).北美洲: 在內華達州與美國加州已知只來自 Amargosa 河流域了。
