L. luminosata Christoph (Figs. 28, 54, 73; Map 6) Lithostege luminosata Christoph, 1885: 127, pl. 6, fig. 9. Holotype 3, ZISP (examined). Type locality: Askhabat (Turkmenistan) Parsons et al. (1999) erroneousely cited the type locality as ‘Achal-Tekke region’. Lithostege luminosata: Prout, 1914: 174, pl. 12 c; Viidalepp, 1996: 47; Parsons et al., 1999: 546. Material examined. Type material: Holotype 3: ‘[Turkmenistan] Askhabat’, ‘Coll. Great Knjaz Nikolaj Mikhajlovich’, [28 April]’; coll. ZISP. Additional material: 4 3, 3 Ƥ: 1 3: [locality is not mentioned] 632 Samml.

Pani leg., gen. prep. 3480, J.V.; all in IZBE. Preparations of genitalia: 1 3, 1 Ƥ. Description & Diagnosis. Wingspan 17–23 mm. Light sandy brown, with indistinct paler and darker transverse bands across forewing, more or less in parallel to distal margin. Similar to L. parva, which is of the same size, but distinguished by the more clearly defined wing markings and the darker hindwings in parva; also similar to L. luigi, but differing from itby the absence of darker scaling on veins crossing the postmedial band and by smaller size(Fig. 28). Male genitalia (Fig. 54) are characterized by a horn-shaped, curved projection from the middle of costa and a relatively short but strong dorsal arm of harpe, which is spined in its distal half. The harpe is formed like a triangular process, arising from the middle of the valve, the latter strongly sclerotized except the distal part. Female genitalia (Fig. 73) with a large, strongly sclerotized, funnel-shaped antrum, ductus bursae very short, corpus bursae membranous, without internal spines, a small diverticulum present. Bionomics. All specimens studied are collected in April and May (in semidesert areas). Additional data on distribution based on literature sources. Shchetkin (1965 a): SW Tajikistan, Vahkhs valley; Viidalepp (1988): Kopet-Dagh (Khorasan-e Shomali). Distribution. From northern foothills of Kopet-Dagh (Turkmenistan) to western Tajikistan (Map 6). May also be present at the Iranian side of Kopet-Dagh.Published as part of Sh, Hossein Rajaei, Stüning, Dieter & Viidalepp, Jaan, 2011, A review of the species of Lithostege Hübner, [1825] 1816 (Lepidoptera: Geometridae, Larentiinae), occurring in Iran and adjacent countries, with description of two new species from Iran and Pakistan, pp. 1-46 in Zootaxa 3105 on page 22, DOI: 10.5281/zenodo.27920
