Description. Adults (Pl. 1, Figs 5 a, 5b and Pl. 2, Fig. 5 c).

Measurements. Wingspan: 31–34 mm (Ƌ), 26–29 mm (♀); forewing length: 14–17 mm (Ƌ), 15–17 mm (♀); forewing width: 12 mm (Ƌ), 10–13 mm (♀).

Wings. Upper side ash-gray to brownish; antemedial line slightly visible or absent; postmedial line rather continuous; discal spot occasionally indistinct.

Male genitalia (Pl. 3, Figs 5 d, 5e). Total length: 1.91–1.99 mm; valvae span: 1.15–1.36 mm; valvulae span: 1.37–1.59 mm; valvae width: 0.60–0.64 mm. Costa padded, sparse costal thorns pooled to a subterminal cactus– like structure; uncus medium–broad, rounded with slender peak; gnathos strongly sclerotized, bulb–like, laterally compressed, moderately pointed and roof–shaped; juxta weakly sclerotized, caudally broadened; aedeagus length: 0.68–0.81mm; appendix aedeagi: 0.93–1.08 mm.

Female genitalia (Pl. 5, Fig. 5 f). Total length: 2.83–3.18 mm; antrum length: 0.60–0.62 mm; antrum width: 0.30–0.33 mm.

Diagnosis. The following species appear to be similar to G. puengeleri : G. fractifasciaria , G. sabine , and G. stemmataria . For distinction see diagnoses of the respective species.

Distribution ( Fig. 5 ). Two of the examined specimens of G. puengeleri originate from the so called “Fergana region” in Kyrgyzstan: the lectotype (male) from the Alai Mountains and the paralectotype (female) from the province Naryn (Togus–Torau, about 2000 m). Two further specimens were captured in South– East Kazakhstan: there is a male from around Almaty (2600 m) and a female originating from the Transili–Alatau south of Medeo (about 2000 m). G. puengeleri was also recorded (as G. alaianus ) from Kyrgyzstan (river Terek, northern slope of the Alaiski mountain range), and from Transalai Mountains, Tshatkal, south–east of lake Issyk–Kul ( Viidalepp 1988), east of Naryn in Kyrgyzstan, and from the Alma–Ata National Park in Kazakhstan at altitudes between 1700 m and 2900 m ( Kaila et al. 1996).

Biology. The flight period lasts from early July to the end of August (see Viidalepp 1988, Kaila et al. 1996).

Remarks. Gnophos puengeleri , that has been considered to be synonym of Chelegnophos stemmataria (= orbicularia ) since Parsons et al. (1999) is herewith reinstated as bona species. Chelegnophos alaianus Viidalepp, 1988 is recognized to be conspecific with Gnophopsodos puengeleri ( Bohatsch, 1910) .

Based on available molecular data the nearest species of G. puengeleri is G. fractifasciaria with a COI distance of 4.77% (see also Tab. 1 and Fig. 6 ).
