Evergestis infirmalis (Staudinger, 1870)

Material examined. HMIM: Iran, Fārs Prov.: 1 ♂, 14 km NE. Khosrow Shirin, Ābsiāh Mt. , 2560 m, 19.viii.1978, Pāzuki, Borumand leg. ; Khorāsān-e Jonubi Prov.: 1 ♂ 2 ♀♀, NE. Birjand, Gomenj , 2.v.2008, Trusch leg. ; Māzandarān Prov.: 1 ♀, Malār , 8.vii.1971, Hāshemi, Zairi leg. (GS: HA-2031, HA-2044).

Distribution. Greece, European Russia, Turkey, Syria, Iran: Kandovan Rd. ( Rebel 1901; Zerny 1939; Goater 2005).

Remarks. The external appearance and male genitalia of the examined specimens are clearly in agreement with Goater's (2005) statements, with the only exception of teeth on the ventral surface of gnathos. As stated by Goater (2005), a few faint indications of teeth present on the ventral surface of gnathos; while in the examined males, the small teeth at this area are distinct, extending from the apex to two-thirds of its length along the shaft ( Figs 7C, F ).

This species could be distinguished from E. caesialis and E. comealis by the shape of uncus and gnathos, dentition of gnathos, and shape of cornuti ( Figs 2E–I , 7A, C, D, F, G, I ). In E. infirmalis , uncus is duck-beak-shaped with the tip being slightly upturned, and the toothless end of gnathos is shorter than that of E. comealis ( Figs 7A, C, D, F ).
