Aphanius saourensis Blanco, Hrbek & Doadrio, 2006 Apricaphanius saourensis, the Sahara aphanius or Sahara killifish, is a species of freshwater pupfish belonging to the family Aphaniidae.

[1][2][3] It is endemic to the Oued Saoura river basin in Algeria.

Later surveys have not encountered the species, although a captive population exists; it was last evaluated by the IUCN 2021 and listed as critically endangered, possibly extinct in the wild.

[1][4][5][6][7] The species name, saourensis, comes from "Saoura", the valley where the fish was collected.

[1] Like all members of the genus Apricaphanius, the Sahara aphanius exhibits sexual dimorphism.
