( Figs. 23–25View FIGURES 21 – 29, 48View FIGURES 46 – 53, 54, 55View FIGURES 54 – 55. 54)

Dasypolia tuektiensis Zolotarenko, 1993  , Siberian Biological Journal 3: 42 (Type-locality: Russia, Altai, Tuekta depression, valley of the Ursul river).

Material Examined. Holotype: male, 2.ix. [19] 62, G[orny]. Altai, Tuekta depression, Ursul riv., meadow, GZ [G. Zolotarenko leg.] (in Russian) Genitalia prep. by G. Zolotarenko, vesica everted by V. Dubatolov [Coll. SZMN]. 1 female, 03.v. 2010, Altai Republic, Ulagan district, 3 km W of Aktash village, shrubby stony steppe, h = 1350 m. 50 ° 19 ' N, 87 ° 35 ' E. On light. Volynkin A.V. leg. (AVB); 1 female, 24.iv. 2009, Altai Republic, Ulagan district, Aktash village, bottom of southern steppe stony slope, h = 1350 m. 50 ° 19 ' N, 87 ° 35 ' E. On light. Nakonechny A.N. leg. (AVB).

Diagnosis. Externally the female of D. tuektiensis  ( Figs. 24, 25View FIGURES 21 – 29) differs from D. fraterna  ( Fig. 27View FIGURES 21 – 29) by apically less elongate forewing, prevailing of grey tints in the forewing colour, wing pattern formed by antemedial and postmedial lines almost converging near to the anal margin. The female genitalia of D. tuektiensis  ( Fig. 48View FIGURES 46 – 53) differs from D. fraterna  ( Fig. 47View FIGURES 46 – 53) by narrower sclerotised part of ostium bursae having longer sclerotised postero-caudal processes, larger lateral flap of ductus, anteriorly less sclerotised ductus bursae. Distinguishing features of D. tuektensis  from D. bubnovae  sp. n.: are described in the diagnosis of D. bubnovae  .

Redescription. External morphology ( Figs. 23–25View FIGURES 21 – 29). Externally variable species. Wingspan 34–42 mm, length of forewing 15–18 mm. Male antennae serrate and fasciculate. Female antennae filiform. Labial palps short, porrect. Female much darker than the male. Head, thorax, abdomen and ground colour of forewing olive brown in males and blackish grey in females. Antemedial and postmedial lines thin, dark, almost converging near anal margin; antemedial line strongly dentate; postmedial line repandodentate. Subterminal line wavy, dentate, generally obscure. Terminal line dark, thin, interrupted. Medial area shadowed. Terminal area slightly paler than subterminal. Orbicular pale, very small; reniform narrow, pale, with dark semilunar nucleus. Cilia pale, brown or grey brown. Hindwing brown in male and grey with brownish suffusion in female. Medial line thin, grey, obscure. Discal spot dark, semilunar, weak. Cilia pale, ochreous in male and grey brown in female. Male genitalia unknown. Female genitalia ( Fig. 48View FIGURES 46 – 53). Ovipositor short, broad; papillae anales rectangular. Gonapophyses moderately long. Ostium bursae trapezoidal, anteriorly slightly broadened, with short sclerotized postero-caudal margins and ventro-lateral sclerotisation. Ductus bursae long, sclerotized, flattened, anteriorly conically narrowed along left margin after the lateral flap of ductus; anterior end of ductus bursae membranous. Lateral flap of ductus rather long, broad, strongly sclerotised, left-positioned. Appendix bursae broad, rounded, membranous; corpus bursae broad, sack-like, membranous.

Bionomics & Distribution. The species inhabits dry mountain stony steppe biotopes with shrubs on southern slopes and river valleys. D. tuektiensis  is known only from the Central part of Russian Altai.

Notes. The species belongs to D. fraterna  species group which includes more than 9 species, distributed in mountainous regions of Asia from Iran to Mongolia (L. Ronkay, pers. comm.); only two of these are described – D. fraterna  and D. tuektiensis  . Unfortunately, upon investigation, the type specimen of D. tuektiensis  has a gluedon abdomen that belongs to Tholera cespitis  ([Denis et Schiffermüller], 1775) ( Noctuidae  , Hadeninae  ) ( Figs. 10View FIGURES 1 – 10, 44, 45View FIGURES 40 – 45). Hence, it is described and illustrated with the genitalia of Th. cespitis  ( Fig. 44View FIGURES 40 – 45). The diagnosis in the original description ( Zolotarenko 1993) says: “The new species is related to Dasypolia fani Stgr.  and the recently described D. dichroa Ronkay et Varga  , and differs from them by the wing shape and coloration, genitalia morphology”. However, the male genitalia of D. tuektiensis  is still unknown.
