The species is distributed throughout much of southern Iran, particularly in the Zagros mountains.

They are dark grey on top and white underneath.

They are found in habitat ranging from barren rocky hillsides to wetter regions.

Graphodatsky et al. (2000) recovered three distinct karyotypes from different regions throughout the range of C. bailwardi (2n=37, FNa=44; 2n=52, FNa=56; 2n=50, FNa=50).

Vorontsov et al. (1979) emphasized how little is known about the species and that the current definition is based largely on distribution.
