This study was conducted to determine taxonomic and zoogeographic features of fishes from the Kor and Helleh River basins in southwestern Iran. The specimens were collected from 2004 to 2007. Twenty four species belonging to 20 genera, 9 families, and 6 orders from the Kor River basin and 21 species belonging to 19 genera, 8 families, and
6 orders from Helleh basin were identified. Ichthyofauna of Helleh basin included some
species not present in the Kor basin: Luciobarus barbulus, Tor grypus, Carasobarbus luteus,
Garra rufa, Mastacembelus mastacembelus, Glyptothorax silviae, and Cyprinion cf. macrostomum.
The Helleh basin ichthyofauna is a combination of western (Ethiopian) and eastern (Oriental) fauna. The cyprinid genera, Barbus, Alburnus, Capoeta, and Chondrostoma should be revised using both molecular and morphological data.
