Diagnosis. The species is closely related to G. streliciellum and was considered a synomym of the latter. For differences see below under “Remarks”. G. cinctipunctella is characterized by grey forewing with black markings and reddish brown spots. Due to considerable external variability the species can hardly be separated from the sympatrically distributed G. streliciella except for the size (14–15 mm in G. streliciella and 15.8–21.2 mm in G. cinctipunctella ). The forewing of G. streliciella is usually darker, blackish grey, with a poorly expressed reddish brown pattern. G. hoefneri known from the south-eastern Alps, is subequal in size to G. cinctipunctella but it is darker, with a more strongly developed black pattern. The male genitalia are characterized by the following combination of the characters: distal portion of the sacculus long, narrow, strongly downcurved; hump on the posterior margin of the vinculum shifted laterally towards the sacculus. The apophysis anteriores broadened in the basal half are characteristic of the female genitalia. Redescription. Adult (Figs 16–20). Wingspan 15.8–21.2 mm. Head light grey, neck dark grey to brown, frons white, labial palpus pale, segment 2 mottled with brown on outer and lower surface, inner and upper surface white, segment 3 with two brown rings; scape brown, other antennal segments brown with light grey rings at base; thorax and tegulae brown; forewing covered with grey-brown tipped scales, subcostal area distinctly mottled with ochreous scales from base to 3/4, three or four black dots surrounded with ochreous in cell, black spot of irregular shape on 2/3 under costal margin, diffuse dirty-white oblique fascia from 1/5 of costa to about 1/3 of dorsum, black touch in middle of fold, white costal and tornal spots forming a diffuse fascia on 3/4, base and subapical area mottled with black, cilia grey-black-tipped; hindwing and cilia grey. Variation. Coloration variable. Some specimens are uniformly grey or light brown with reduced markings or grey with black spots in cell but without reddish-brown scales. Male genitalia (Figs 39–45). Uncus moderately narrow, apex triangular, pointed; gnathos short, weakly curved, narrow; tegumen narrow, anteromedial emargination deep, triangular; valva broad in basal third, then slender, weakly inwardly curved, apex inflated, weakly pointed; sacculus broad at base, distal portion long, narrow, strongly downcurved, gap to vincular process large; vinculum broad, posterior margin with broad medial emargination and with short triangular lateral process; saccus triangular, moderately narrow, top abruptly truncated, not extended beyond top of pedunculus; phallus narrow, pointed, with small subapical arm, caecum inflated, about 1.5 times shorter than phallus. Variation. Valva and sacculus vary in length and width. Female genitalia (Figs 60, 61). Papillae anales elongate, subtriangular, densely covered with short setae; apophysis posteriores narrow, more than two length of segment VIII; segment VIII subrectangular, longer than broad; subgenital plates folded medially, separated with moderately broad membranous area covered with fine microtrichia and weakly narrowed anteriorly; posteriolateral sclerites large, triangular with rounded posterior corners, anterior corner weakly projected anteriorly; anterior margin of sternite VIII strongly sclerotized, concave with paired medial projections; apophysis anteriores about as long as segment VIII, strongly broadened at base; colliculum as broader as long, ductus bursae narrow, inflated in distal portion; corpus bursae large, subovate, shorter than ductus bursae, signum near entrance of corpus bursae, base small, distal portion hook-shaped, strongly curved, tapered. Variation. Segment VIII varies in length, its length/width ratio varies from 0.6 to 0.8. Biology. Host plant unknown. The adults occur from late June to late August in steppe biotopes from 900 to 2200 m elevations. Distribution. China (Gansu, Hebei, Inner Mongolia, Ningxia and Qinghai), Mongolia, Russia: South Ural (Junnilainen et al. 2010), Altai, South of Krasnojarskiy krai, Zabaikalskiy krai, Amur Region (Povolný 2002; Ponomarenko 2008; Bidzilya 2009). Remarks. Gelechia cinctipunctella Erschoff, 1877 was described from a single male collected in Albasino, Amur region of Russia. It was considered a subspecies of G. streliciellum (Povolný 1992, 2002; Huemer & Karsholt 2010) because of its large size and grey forewing with distinct black markings. Recently G. cinctipuncetella was synonymized with G. streliciella (Ponomarenko 2008). G. mongolorum was described from 20 specimens of both sexes collected in Mongolia. The drawing of the genitalia of the female holotype from Chalchingol (Chojbalsan aimak) is given in the original description (Povolný 1969, Pl. 3, fig. 5), although the male paratype from the same locality is not figured. Based on the drawings, the male paratype from Mörön (Povolný 1969, Pl. 2, fig. 4) and the female paratype from “Uubulan am Fluss Tola” (Pl. 4, fig. 9) must be referred to G. fuscescens sp. nov. Being originally described as a separate species G. mongolorum was later included as a subspecies in the “ G. streliciellum-mongolorum-cinctipunctellum -complex” which ranged from Europe to Amur region (Povolný 1992). Our study of extensive material from southern Siberia and northern China showed that large specimens ( G. cinctipunctella ) can occasionally be found among more abundant, smaller specimens of G. mongolorum that are varied both in size and in wing markings. The genitalia of both sexes of G. mongolorum match well those of G. cinctipunctella . The main differences are in the sacculus that is very long and outwardly curved in G. cinctipunctella and usually shorter and inwardly curved in G. mongolorum . However, we found that this character is quite variable and intermediate forms occur among sympatrically collected specimens. Hence, we consider G. mongolorum Povolný, 1969 a synonym of G. cinctipunctella (Erschoff, 1877). The specimens of the former “ G. mongolorum / G. cinctipunctellum ” complex differ from G. streliciella in having light grey rather than blackish-grey forewing with a poorly expressed reddish-brown pattern and larger size. In male genitalia the valva is narrower and its apex has slightly tapered inwardly curved tips, the hump in the middle of the posterior margin of the vinculum is shifted laterally towards the sacculus and the tegumen is narrower. The female genitalia of all three taxa are nearly indistinguishable, but the apophysis anteriores are strongly broadened at base in G. cinctipunctella . We consider these to be specific differences and thus re-instate G. cinctipunctella as a separate species. : Published as part of Li, Houhun & Bidzilya, Oleksiy V., 2017, Review of the genus Gnorimoschema Busck, 1900 (Lepidoptera, Gelechiidae) in China, pp. 173-195 in Zootaxa 4365 (2) on pages 180-182, DOI: 10.11646/zootaxa.4365.2.4, http://zenodo.org/record/1117538 : {"references": ["Erschoff, N.
