Corydoras adolfoi – Adolfo’s Cory

Type locality is given as ‘Small tributary of the upper Rio Negro on the equator near São Gabriel da Cachoeira, Brazil’, and this species is apparently highly endemic there.

Some sources state that it also occurs in the rio Uaupés (known as ‘Vaupés’ in Colombia), a major tributary of the Negro, but we’ve been unable to obtain confirmation thus far.
