barbus sublimus, described by coad and najafpour (1997) as a new species, was retrieved first from the aala rood, a river in khuzestan province, southwestern iran. in our latest sampling a population of this species was found, for the first time, in fahlian rood, a river in a different water basin, in fars province, southwest of iran, where no specimen of the species was collected in previous samplings at this location. the detail of taxonomic work done on the specimens captured, species phylogeny, and the possibilities of its previous absence and then presence are described and discussed.
