Lithostege stadiei Lehmann, 2011: 249 –251. Holotype 3, coll. L. Lehmann, will later be deposited in coll. ZMHB (examined). Type locality: NE Zanjan ( Iran).

Material examined. Holotype 3: ‘ Iran, Prov. Zanjan, 20 km NE of Zangan [Zanjan], 2220m, 36° 42' N; 48° 45' E, 25.X.2000, leg. B. Benedek & Gy. Fábián, col. György Fábián / Hungary’, ‘ Holotype 3 Lithostege stadiei Lehmann, L. Lehmann’, ‘Gen. Prep. Nr. 10/2008’; in coll. L. Lehmann.

Description & Diagnosis. Wingspan 29 mm, a little smaller than L. buxtoni . Forewing palebrown, with a smooth, black line from apex to basal area of forewings, highlighted proximally by a broad white band ( Fig. 6 ). In the somewhat similar L. buxtoni , this line is strongly waved distally and terminates at the middle of the hind margin. Hindwings white, without any pattern. Male genitalia highly similar to those of L. buxtoni ( Fig.37 ), but basal process of valve narrower, with almost pointed tip, terminal half of uncus gradually tapering towards apex, the latter not truncate. Aedeagus shorter, almost straight. Female unknown.

Distribution. Known only from type locality (NW Iran) (Map2).
