Diagnosis

The new species is very similar to P. redikorzevi Spassky, 1940 from which it differs by the shape of the tibial apophysis (with longer claw-like tip, and smaller dorsal lobe).

Etymology

The specific epithet is an adjective and refers to the unexpected discovery of a new species of this genus in Iran.
