Holotype ♂ : Brasilien , Santa Catarina , S. Bento do Sul , Serra Rio Natal , 850 m , Feb. 1999 , leg. H. Thöny (GenPr- Heterocera MWM 28.534 ) ( MWM ) ; Paratype 1 ♀ : Brasilien , Santa Catarina , S. Bento do Sul , Serra Rio Natal , 850 m , April 1999 , leg. H. Thöny (GenPr- Heterocera MWM 37.002 ) ( MWM ) . Description . Male. Length of fore wing 15 mm . Fore wing very narrow, dark-brown, with light-brown transverse bands (of thin undulated lines) discally, postdiscally and submarginally, fringe mottled brown at veins (in thick bundles), light-brown between veins. Hind wing white coal-black in middle, basally and distally, fringe black unicolorous. Male genitalia. Uncus robust, forked, halves diverged to sides at acute angle, apices uneven; gnathos arms very short, thin; costal and abdominal edges of valve practically smooth, outer edge semicircular, apex slightly extended; juxta robust, scaphoid, with relatively short abdominal process semicircular apically, saccus very long, fisiform, apically sharp; phallus short, basally swollen, vesica without cornuti. Female. Length of fore wing 15 mm . Fore wing slightly wider than that of male, dark-brown, with pattern of light-brown thin undulated lines forming bands discally, postdiscally and submarginally, fringe mottled: brown at veins (in thick bundles), light-brown between veins. Hind wing dark-brown, without pattern, fringe unicolorous, dark-brown. Female genitalia. Ovipositor short; papillae anales semicircular, wide, densely covered with small spikes; anterior and posterior apophyses very short, thick, practically of equal length; ostium wide, cup-like, framed with poorly sclerotized plate; ductus of bursae copulatrix short, membranous, relatively wide; bursa copulatrix bag-like, without signa. Diagnosis . Externally, the new species differs sharply from all the other species of the genus by its narrow fore wing. In this feature it is similar to D. turgenevi Naydenov, Yakovlev, Penco & Sinyaev sp. nov. , but differs in its bigger size and the very long fusiform saccus. Distribution. Brazil , Santa Catarina . Etymology. The new species is named after the Russian writer Lev Nikolayevich Tolstoy.
