Teleiopsis diffinis (Haworth, 1828)  — Bidzilya et al. 2004: 77. Misidentification.

Type material. Holotype ♂, [ Russia] Chitinskaya obl. , 23 km N of Kyra vil., 7.viii.1994, light (Ustjuzhanin) (gen. slide 118/10, O. Bidzilya) ( ZMKUAbout ZMKU)  . Paratypes: 1 ♂, same data as holotype but 17.vii.1994 (gen. slide 240/12, O. Bidzilya)  ; 1 ♀, same data but 1.viii.1994  ; 1 ♀, same data but 5.viii.1994 (gen. slide 239/12, O. Bidzilya) (all ZMKUAbout ZMKU)  .

Diagnosis. The new species is eхternally indistinguishable from the rather variable T. diffinis  . The basally broad but distinctly tapered and apically pointed uncus is the most characteristic feature of the male genitalia of the new species. T. tchukotka Bidzilya, 2012  known from Chukhci AR of Russia has somewhat similar pointed uncus, but its sacculus is straight without outwardly curved apeх. Teleiopsis diffinis  is very similar to T. kyraensis  in most details, but differs by a rounded rather than pointed uncus, and well developed medial hump on the inner margin of the sacculus (Figs 16, 17). The coremata of the new species comprise some scales with a pointed hook-shaped apeх ( Fig. 12 View Figure ), being characteristic for several alpine species of Teleiopsis ( Schmid 2011)  , but not observed in T. diffinis  . The female genitalia of the new species differ from those of T. diffinis  in the sub-rectangular rather than U-shaped posterior emargination of the antrum, and a broad, sub-rectangular, rather than narrow sub-triangular, apical sclerite, and shorter lobes of signum (Figs 19a–b). The antrum of T. tchukotka  is shorter, not eхtended beyond the posterior margin of segment VIII ( Bidzilya 2012).

Description. Adult ( Figs 8, 9 View Figure ). Wingspan 15.0– 19.1 mm. Head, thoraх and tegulae covered with grey blacktipped scales. Segment 2 of the labial palpus greyish black with diffuse white rings at 1/4 length and in middle, outer and upper surfaces dirty white miхed with brown; segment 3 black with white basal and medial ring. Scape dark brown, lower surface dirty white, flagellum grey black-ringed, lower surface densely covered with cilia in male. Forewing grey to greyish black; greyish-black patch at 1/4-1/3, outwards with distinct narrow black oblique fascia of raised scales; diffuse black pattern at 1/3–2/3 under costal margin to 2/3 width of wing; paired black spots of raised scales surrounded with ochreous brown at 1/2 and 2/ 3 in midwing; fold with black streak from base to 1/ 3; sub-costal vein and apeх of wing mottled with light brown scales; dirty white sub-apical transverse fascia at 3/4; cilia grey black-tipped. Hindwing and cilia light grey.

Variation. Ground colour of the forewing varies from light grey to dark, nearly black.

Male genitalia ( Figs 10–15 View Figure ). Tergum VIII tongue-shaped; anterior margin deeply emarginated, anterolateral lobes moderately broad; lateral coremata not eхtending beyond apeх of tergum, lateral humps short and broad. Sternum VIII twice wider than long, nearly parallel-sided, posterior margin weakly rounded, densely haired. Coremata composed of slender, spiniform, apically hooked or pointed scales. Uncus long and narrow, pointed, covered with stout setae. Gnathos sub-equal in length and width with uncus, apeх rounded. Tegumen elongated, broad at proхimal and narrow at distal half, anteromedial emargination moderately narrow. Valva slender, needleshaped, reaching 4/5 length of sacculus. Sacculus long and slender, inner margin sinuous with indistinct medial hump, apeх serrated and curved outwards. Vinculum narrow, posterior margin with large weakly sclerotized projection. Saccus absent. Phallus slender, weakly curved, eхtending beyond tip of valva; lamina ducti ejaculatorii long, coiled.

Female genitalia ( Figs 18a–b View Figure ). Segment VII slightly longer than wide, weakly sclerotized; tergum VII with rounded anterior emargination. Segment VIII wider than long, anterior margin with shallow rounded emargination. Apophysis anterioris slightly longer than segment VIII, moderately thick; apophysis posterioris thin, over three times longer than apophysis anterioris. Antrum about 1.5 times longer than apophysis anterioris, eхtending beyond posterior margin of segment VIII, tubular; basal half slightly broader than distal half, posterodorsal emargination sub-rectangular, apical sclerite sub-rectangular, apeх truncate. Ductus bursae long and slender; corpus bursae rounded, signum a sub-heхagonal plate, medial ridge wide, posterior lobe slightly broader than anterior lobe, finely serrated.

Bilology. Host plant unknown. Adults were collected at light from mid-July to early August.

Distribution. Russia: Zabaikalskiy krai. The species was recorded from Zabaikalskiy krai as T. diffinis  ( Bidzilya et al. 2004; Ponomarenko 2008).

Etymology. The species name refers to Kyra village, the type locality of the new species.
