Remarks. The Iranian specimens used for recording this species ( Dlabola, 1985) were deposited in in National Museum of Prague. Dlabola (1985) considered C. rufus as a Hyrcanian element in Caucasus mountains and neighboring forests. He recorded this species in four locations in the north, along the coasts of Caspian Sea, and northeast ( Fig. 6G) which show the eastern and southern borders of the overall distribution of the species. The coasts of the Caspian Sea in the north of Iran is a part of the Caucasian- Euxino-Hyrcanian province of Euro-Siberian region as considered by Frey & Probst (1986). The distribution of the species in this zone is consistent with Dlabola’s zoogeographic comment of the species. The Caspian Zone is restricted to Caspian Sea in north and wall-like Alborz mountain in south, and is connected to the Khorasan zone in the east. The two zones were shown to have the highest degree of similarity based on the number of common endemic species ( Mozaffarian, 2013). It is conceivable that the distribution of the species in the east is the result of dispersal after ending the barrier of the Alborz mountain chain to the east.
