Chirostoma bartoni, the Alberca silverside, is a species of neotropical silverside endemic to the Lerma River basin of Mexico.
Typical adult specimens are approximately 7.1 cm in length.
[1] The Alberca silverside was found only in the Alberca Caldera, Guanajuato, Mexico and likely became extinct when the caldera temporarily dried up in August 2006.
[2] The specific name honours Barton Appler Bean (1860-1947) who was Assistant Curator of Fishes at the U.S. National Museum.
