The dorsal fin bears elongate blotches on the posterior half of each fin membrane, usually fading distally, but in some fish occupying the whole membrane.Proximally there is a gap between these blotches and 3-5 bars which originate at the posterior edge of the base of branched ray three and succeeding rays, and extend distally across the ray and then along the ray and the membrane to the gap.Karyotype analysis separates this species from Garra rufa (Esmaeili et al., 2009). V") according to Berg (1913) where the original description is founded on these fish, implying all are types.

There is a transverse depression anterior to the nostrils on the snout.
A postspawning individual from the Hormuz basin measuring 148.7 mm SL has small tubercles under the eye running forward onto the snout as a band, the most evident tuberculation. The top of the head has tubercles but these are smaller and sparser than the band under the eye.
