Dasypolia bubnovae Volynkin

Volynkin, Anton V., 2012, A review of the genus Dasypolia Guenée, 1852 from the Russian part of the Altai Mountain Country, with descriptions of two new species (Lepidoptera, Noctuidae), Zootaxa 3478, pp. 416-428 : 428

Dasypolia bubnovae Volynkin sp. n.

( Figs. 26 , 49 , 54 )

Material Examined. Holotype: female, Altai, Kucherla. T. Bubnova [leg.] (in Russian) [Coll. SZMN].

Diagnosis. The new species is well separated from D. fraterna and D. tuektiensis . Externally it differs from D. tuektiensis ( Figs. 24, 25 ) by narrower elongate forewing, reniform stigma without dark nucleus, and brownish-grey hindwing (in D. tuektiensis hindwing grey with sparse brownish suffusion). From D. fraterna ( Fig. 27 ) it differs by more rounded forewing with less elongate apex, absence of dark nucleus in reniform stigma, and grey colours of the forewing. The female genitalia of the new species well differs from D. tuektiensis ( Fig. 48 ) and D. fraterna ( Fig. 47 ) by shape of sclerotisation of ostium bursae. In D. bubnovae sp. n. sclerotisation of the ventral part of ostium bursae as wide plate with broad triangular postero-caudal processes, but in D. tuektiensis and D. fraterna sclerotised area is very narrow, without postero-caudal processes; ductus bursae without anterior conical narrowing below leteral flap, appendix bursae broader.

Description. External morphology ( Fig. 26 ). Wingspan 35 mm, length of forewing 15 mm. female antennae filiform. Labial palps short, porrect. Head, thorax and abdomen and ground colour of forewing blackish grey. Antemedial and postmedial lines dark, slender, almost join near anal marging; antemedial line strongly dentate; postmedial line repandodentate. Subterminal line wavy, dentate, diffused. Terminal line dark, slender. Medial area shadowed. Terminal area slightly paler than subterminal. Orbicular and reniform whitish, small; reniform without dark nucleus. Cilia pale, brownish grey. Hindwing brownish grey, with grey, obscure, slightly wavy medial line. Discal spot dark, semilunar, very weak, poorly defined. Cilia pale, greyish ochreous. Male unknown. Female genitalia ( Fig. 49 ). Ovipositor short, broad; papillae anales rectangular. Gonapophyses moderately long. Ostium bursae trapezoidal, ventrally strongly sclerotised as wide plate with broad triangular postero-caudal processes. Ductus bursae long, sclerotised, flattened, anteriorly membranous. Lateral flap of ductus rather long, wide, strongly sclerotised, leftpositioned. Appendix bursae broad, rounded, membranous; corpus bursae broad, sack-like, membranous.

Bionomics & Distribution. Occurs in river valleys, and is known only from its type locality, the Katun river valley near the Kucherla village in the western part of Russian Altai.

Etymology. The species name is dedicated to T.V. Bubnova, who collected the type.
