Gelechia streliciella Herrich-Schäffer, 1854: 171 , pl. 67, fig. 495. Type locality: Germany: Neustrelitz. Gnorimoschema streliciella (Herrich-Schäffer, 1854) : Povolný, 1966: 393.

Material examined. CHINA: 2 ♀, Halawubeigou, Mt. Helan , Alxa Left Banner , Inner Mongolia, 2200 m, 7.viii.2011 (Lixia Li & Yinghui Mu) (gen. slide nos. 74/14; 89/14, O. Bidzilya) ( NKU).

Additional material studied. RUSSIA: 1 ♂, Zabaikalie, Selenginsk, 17.vi.1959 (Kolmakova) (gen. slide no. 144/ 14, O. Bidzilya) ( ZIN).

Diagnosis. G. streliciellum is characterized by dark greyish-black forewing with black spots surrounded with reddish-brown scales and a diffuse dirty white oblique fascia at base. G. cinctipunctella is lighter, grey rather than black, and usually larger; G. nordlandicolella is larger, lighter, more uniformly coloured, without white markings at the base of the forewing and with white labial palpus. The male genitalia are characterized by the long, narrow, strongly downcurved distal portion of the sacculus in combination with the narrow elongated saccus and the hump on the posterior margin of the vinculum that is placed medially. The large triangular posteriolateral sclerites, the apophysis anteriores broadened in basal 1/ 3 in combination with nearly subqadrangular segment VIII are characteristic for the female genitalia. The genitalia of both sexes are most similar to those of G. cinctipunctella and G. rufomaculata sp. nov. For the differences see below under the “Remarks” for these species.

Description see Huemer & Karsholt 2010.

Biology. The larvae were reported from Antennaria dioica L. (Gaertn.) ( Asteraceae ) in Europe. The life style of larvae is described ( Huemer & Karsholt 2010). In China adults were collected in early August at an elevation of 2200 m.

Distribution. Northern and parts of Central Europe ( Huemer & Karsholt 2010), Russia (Middle Volga region, Burjatia; the examined records from other regions of the southern Siberia (Bidzilya 2009) must be referred to the next species), China: Inner Mongolia Autonomous Region.

Remarks. Both females from China match well externally specimens from Europe but are smaller. Sternite VIII in the female genitalia is slightly broader and its anterior margin is more strongly sclerotized compared with the specimens from Europe. Moreover, the apophysis anteriores are broader at base in specimens from China. The male genitalia of the specimen from Selenginsk have shorter saccus and distally broader sacculus (see Huemer & Karsholt 2010: fig. 11 for comparison). These differences suggest that the specimens from China and Russia may represent a distinct species, but this needs to be tested by the study of additional material.
