Poblana Explained

Poblana is a genus of Neotropical silversides that are endemic to Mexico, with each of the four threatened species restricted to a single Oriental Basin maar lake. They are small fish that do not surpass in standard length.^[1]

Species

FishBase recognizes four species in this genus, although genetic differences between them are very limited and some regard all as subspecies of P. alchichica.^[2] Poblana is sometimes included in Chirostoma instead of being regarded a separate genus.^[1]

• Poblana alchichica F. de Buen, 1945 (Alchichica silverside)
