Diagnosis. Based on external characters this species can easily be confused with I. rufaria (Hübner, 1799) , I. consanguinaria (Lederer, 1853) and I. ochrata (Scopoli, 1763) . As all of these species are present in Iran ( Hausmann 2004; Rajaei et al. 2023), a diagnosis of I. admiranda is given here and compared against these three species.

Ground colour sandy yellow, discal spots present (sand, ochreos or light brown coloured, discal spots present in I. rufaria ; similar in I. consanguinaria , but ground colour more leather coloured; light brown with an orange or reddish tinge, discal spots absent in I. ochrata ) ( figs 1–2 ; and Hausmann 2004: pages 63–64, 66–69, 75–76; plate 3). In male genitalia valva with two spines at the tip (with one spine at the tip in I. rufaria ; without any spine in I. consanguinaria ; with one hook at the tip on the ventral side in I. ochrata ); aedeagus very large, cornutus about one third of the aedeagus length (short, cornutus about half the aedeagus length in I. rufaria ; cornutus about two third of the aedeagus length in I. consanguinaria and I. ochrata ) ( figs 1–2 ; and Hausmann 2004: pages 493, 494). In female genitalia ductus bursae long and broad, corpus bursae slightly twisted with spines and membranous broad process (ductus bursae similar, corpus bursae elongate with spines and membranous process without spines in I. rufaria ; ductus bursae funnel shaped, corpus bursae globular with spines, with membranous process in I. consanguinaria ; ductus bursae long and slender, corpus bursae globular, without membranous process in I. ochrata ) ( figs 1–2 ; and Hausmann 2004: pages 527, 528).

Note. As for Turkey and the Caucasus (see introduction), this species is only known from isolated records in Iran.
