Distribution. East Turkey (Van Province) ( Kemal et al. 2020).

Remarks. All the examined specimens are males, with uniformly brownish-olive forewing and slightly paler hindwing; however, there is an intraspecific variation among them in this regard, as some specimens have a clearly lighter hindwing ( Fig. 20C, D ). This variation is present even among members of a same population (specimens collected in Maku, West Azarbaijan Province). The postmedial line in most of the specimens collected from the north of Iran is hardly visible ( Fig. 20C, D ), but the specimens with brighter hindwings have a more distinguishable postmedial line.

Comparing the male genitalia of the Iranian specimens revealed that in all of them the fibula is slightly shorter ( Fig. 21D, E ) than in P. aerealis ( Fig. 21A, B ), and the shape of the juxta is different from that of P. aerealis ( Fig. 21A, C, D, F ) and similar to that described and illustrated by Kemal et al. (2020) ( Fig. 21A, B ; see also Kemal et al., 2020: 2, 4).

This species is newly reported for the fauna of Iran.
