Аннотация: Lasiommata zagrossica spec. nov. is described from Iran (Chaharmahal-va-Bakhtiyari Prov., Central Zagros, Gardaneh-ye-Cheri Pass, W of Samsami, 2800 m). The new species represents an unique combination of characters, some of which can be found in other species of the genus Lasiommata. The general design of the wing upperside and androconial brand in L. zagrossica are similar to that known in L. maera, L. adrastoides and L. petropolitana. L. zagrossica and L. petropolitana share such typical characters as rounded outline of the forewing, thin transverse median band of the hindwing upperside and discal cell with distinct transverse dark lines. The evenly curved (not undulated) discal line on the hindwing underside is similar in L. zagrossica to that known in L. menava, L. maeroides, L. felix and L. hindukushica.
