Addition to the composition and distribution of tenebrionid beetles of the subtribe Helopina Latreille, 1802 (Coleoptera: Tenebrionidae: Helopini) in Iran

Three new species of tenebrionid beetles of the genera Euboeus Boieldieu, 1865 and Hedyphanes Fischer von Waldheim, 1820 are described from Iran and illustrated: Euboeus (Pelorinus) altimontanus sp. nov. (Mazandaran and Qazvin provinces), Hedyphanes (s. str.) errans sp. nov. (Tehran Province) and Hedyphanes (s. str.) pilosus sp. nov. (Alborz Province). Furthermore, new distributional data for several previously described species of the genus Hedyphanes in Iran are provided. Following the present study, the number of Helopini taxa in Iran has increased to 66 species and one subspecies.
