Type material. Holotype ♀, CHINA Xizhashuicun, Lingchuan County, Jincheng , Shanxi Province, 12– 14,16. vii. 2010, 900 m (Haiyan Bai & Linlin Yang) (gen. slide no. L13035) ( NKU) . Paratypes: 4 ♀, same data as for holotype ; 1 ♀, Xiaoshancun, Qipanshan , Weichang County, Hebei Province, 16.vii.2001 (Yanli Du & Shulian Hao) (gen. slide no. L06003 View Materials ) ; 1 ♀, Jixie forest farm, Weichang County, Hebei Province, 14.vii. 2001, 1546 m (Yanli Du & Shulian Hao) (gen. slide no. 81/08, O. Bidzilya) (all kept in NKU) .

Diagnosis. The species is defined externally by reddish-brown forewing with a well developed black pattern along the costal margin. G. rufomaculata is similar but the black pattern is poorly expressed. The female genitalia are recognizable by very long (subequal in length with the length of posterior margin of sternum VIII) and broad (ratio length/width = 3) posteriolateral sclerites. The posterolateral sclerites of of G. robustella (Staudinger, 1871) are also long, but are considerably narrower (ration length/width = 5). G. steueri has also broad and long postriolateral sclerites, but they are projected anterolaterally, whereas those of G. piskunovi are situated under the posterior margin of sternum VIII.

Description. Adult ( Figs 23, 24 View FIGURES1–24 ). Wingspan 15.5–17.0 mm. Head white, neck brown, labial palpus pale, segment 2 mottled with brown, inner surfce white, segment 3 with brown basal and medial rings, scape brown, other antennal segments brown with white basal rings; thorax and tegulae greyish brown; forewing covered with grey black-tipped scales, subcostal vein, fold and dorsum reddish-brown, three reddish brown spots with black dots inside in cell, costal margin mottled with black with two subtriangular black patches on 1/3 and after mid length, costal and tornal spots white, subapical area and cilia grey black-tipped; hindwing light grey.

Variation. The extent of reddish-brown and black markings varies, some specimens appearing more black and others more reddish brown. The dots in cell are often reduced.

Male genitalia. Unknown.

Female genitalia ( Figs 64, 65 View FIGURES 64–65 ). Papillae anales elongate, subtriangular, densely covered with short setae; apophysis posteriores more than two times longer than segment VIII; segment VIII subrectangular, broader than long; subgenital plates separated with very narrow membranous area covered with fine microtrichia, medially with moderately broad folds, posteriolateral sclerites large, two times broader than long, extended under posterior margin of subgenital plate from the middle to 3/4 width, anterior corner projected to base of apophysis anteriores, lateral corner rounded, anterior margin of sternite VIII weakly sclerotized, straight, with paired medial projections; apophysis anteriores longer than segment VIII, distinctly broadened in basal half; colliculum cylindrical with lateral sclerotization; ductus bursae narrow, inflated in distal portion; corpus bursae about as long as ductus bursae, elongate, signum near entrance of corpus bursae, base stout, distal hook broad, weakly curved with narrow pointed tip.

Variation. The basal plate of signum varies from subrectangular to axe-shaped.

Distribution. China (Hebei, Shanxi).

Etymology. The new species is named in the honor of Vladimir Piskunov (Vitebsk, Belarus) in recognition of his contribution to the study of Palaearctic Gelechiidae .
