Specimen studied total: 55 ♂, 112 ♀.
Differential diagnosis. (Figs 11–12) Wingspan 29–39 mm. Forewing termen slightly convex (R. auctata differing in straight or slightly concave termen). Upper- and underside of wings yellow-orange with a dominant pink postmedial band on all wings, subterminal area suffused with pink scales; antemedial line hardly visible; discal spots pink, round, large (this colour combination is unique and does not allow confusion with any other Iranian Rhodostrophia). Male antennal flagellum ventrally dentated. Male hindtibia with three spurs, pseudospur absent.
Male genitalia (Fig. 65) with a long uncus (but much shorter and thicker than that in R. auctata, Fig. 3); apical part of uncus fusiform (in contrast to all other Rhodostrophia species in Iran, see genitalia plates); valva apically clefted, tongue-shaped elongated, subapically spinulose; sacculus part of valva folded ventrad over the valva. Male sternum A8 bilobed (octavals much larger than those in R. auctata).
Female genitalia (Fig. 82) with an oval, membranous, corpus bursae (twice as large as in R. auctata); ductus bursae chitinized, funnel-shaped towards ovipositor (its anterior part much narrower than that in R. auctata, see Fig. 81).
Genetic data. Two BINs: BOLD:AAC9459 (Turkey) and BOLD: ABZ7093 (Iran), diverging by 2.0% from each other. Nearest species: R. calabra (6.5%) and R. auctata (7.6%) (Fig. 119 & Table 1).
Distribution (Map 3). East Mediterranean species, distributed mainly in Turkey, northern Iraq, Transcaucasus and Caucasus into north-western and northern Iran (provinces Azarbaygan-e Garbi, Azarbaygan-e Sharqi, Ardabil, Zanjan, Qazvin, Kordestan, Teheran; eastwards not exceeding the central Alborz).
Life history and habitat. Biology and larval stages unknown, according to examined material, Amsel collected this species in oak forest (Quercetum). Univoltine, in Iran from early May to mid-July. In eastern Europe (Croatia) recorded from sea-level, in Turkey and Transcaucasus up to 1400 m (Hausmann 2004). In Iran, the specimens were collected from 1300 m up to 2350 m.
