Notes. The three “males” mentioned by Draeseke (1928) are, in fact, females. Draudt (1950) mentioned only one specimen from Shanghai as “ Acronycta niveosparsa ” with the date “ 19.IX.37 ”, however, this specimen could not be found in the collection of ZFMK thus we omitted this specimen from the paratype series. Diagnosis. Adult ( Figs 9–11 ). Narcotica hoenei can be distinguished from its congeners by its smaller size (wingspan 19–23 mm , it is 25–30 mm in the two other Narcotica species); the rather uniform forewing; the reduced orbicular spot; the pale, whitish patch in the apical region of the forewing; the more prominent medial fascia; and the darker greyish crest dorsally on the abdomen. The new species can be distinguished from N . cryptica by the presence of rusty brownish patch between the antemedial and medial lines of forewing. Male genitalia ( Figs 16, 17 ). The new species has smaller clasping apparatus and vesica than in its congeners; somewhat straighter harpe; somewhat curved distal part of the valvae at the junction of the harpe; and more slender, proximally more curved carina field of aedeagus. The structure of the vesica is also different as the armature of N . hoenei is less complex than in the related two species, consisting of 4–7, short cornuti basally, 7–10 medial cornuti of larger size, and less numerous medium-sized cornuti distally with slightly weaker cornuti at the terminal section; the basal and terminal diverticula are less prominent. Male 7 th and 8 th abdominal segments ( Fig. 20 ). The structure of the abdominal segments is closer to that of N . niveosparsa than to N. cryptica and much smaller than those of its congeners. 8 th sternite has more curved lateral sides with narrow section proximally, trapezoidal “window” with less reduced posterior abdominal brush, substituted by wider, slightly more sclerotized, split streak. The bell-shaped 8 th tergite has shorter and slightly narrower proximal part, curved and thicker lateral sides with triangular distal end, and rather rhomboidal “window”. Female genitalia ( Figs 25, 26 ). The shape of the female copulatory organ is closer to N . niveosparsa than to N. cryptica but the entire organ is significantly smaller than in its congeners and the corpus bursae is shorter, and the ductus bursae is narrower than that of N . cryptica . Female 7 th abdominal segments ( Fig. 29 ). There are no significant differences among the three congeners. Description. Adult ( Figs 9–11 ). Wingspan 19–21 mm in males, 20–23 mm in females. Head wide, covered with whitish and some brownish scales; frons smooth; eye rather large, naked; the 2 nd segment of labial palp laterally flattened, covered with longer scales, the 3 rd segment of labial palp almost as long as the 2 nd , covered with small scales, apically heavily pointed; antennae in both sexes filiform, laterally slightly flattened, covered with velvety hairs and sparsely with tiny, stronger, long hairs. Thorax brownish with some whitish scales; patagia and tegulae brownish with some whitish scales, blackish outlined. Forewing in both sexes elongate, apically pointed, ground colour dark greyish-blackish with more or less brownish suffusion; basal-, antemedial- and subterminal lines double, reduced; medial line and shadow conspicuous; postmedial line interrupted, heavily crenulated with black, conspicuous arrow-like spots; terminal line whitish, interrupted with black lines; tornal streak reduced except in the medial shadow; medial field between the antemedial- and medial lines rusty brownish; terminal field pale, whitish with a black, smaller patch in the apex and a slightly larger patch next to M 2 vein; claviform spot absent; orbicular spot reduced, almost absent, outlined only with a thin, blackish line; reniform spot reduced, outlined with black interrupted line; fringes whitish with blackish-brownish spots. Hindwing in both sexes triangle-shaped, apically elongated, brownish; discal line and spot pale, hardly recognizable; tornal spot pale, blackish, tiny; fringes brownish with whitish scales. Abdomen greyish with one larger and one smaller darker greyish crest dorsally on the first two segments. Male genitalia ( Figs 16, 17 ). Uncus moderately long, basally curved, slender, laterally slightly flattened, apically evenly narrowing, pointed, covered with sparse, long, weak hairs. Tegumen developed more or less evenly wide, as long as vinculum; peniculus covered with dense, long hairs. Vinculum narrow, evenly wide. Saccus “V”- shaped, apically heavily pointed. Juxta moderately sclerotized, triangle-shaped, basally widest and somewhat more sclerotized with medial cleft distally. Transtilla relatively wide, moderately sclerotized, long, fused with the base of digitus. Valvae long, more or less evenly wide, ventral margin slightly angular; sacculus developed, more sclerotized; harpe long, apically evenly or abruptly narrowing with rounded end; costa and the dorsally positioned digitus more sclerotized, digitus hooked with rounded end, covered with sparse, long hairs; cucullus elongated with round end; corona sparse, weak, long hairs. Aedeagus sclerotized, ventrally heavily curved; carinal field rather sclerotized, long, laterally protruding, proximally pointed, distally widened. Vesica as long as the aedeagus, tubular, distally widening with a sclerotized, ribbed patch laterally; basal diverticulum absent, terminal diverticulum sac-like, small; basal 4–7 cornuti small, sparse; medial 7–10 cornuti long, sparse, less numerous; distal numerous cornuti rather sparse, gradually shortened and strengthened.

Male 7 th and 8 th abdominal segments ( Fig. 20 ). 7 th sternite longer than wide, slightly trapezoidal, evenly fully sclerotized; proximal edge straight, lateral sides convex, distal edge concave. 7 th tergite quadrangular, longer than wide with a semi-circular, slightly stronger part distally with a larger sclerotized patch in the hardly visible, “U”- shaped “window”; proximal edge straight with two curved, slightly stronger rods; lateral sides convex; distal edge concave. 8 th sternite circa one and half times wider as high, quadrangular; proximal edge horn-like, evenly wide; lateral sides parallel, proximally narrow, inner margin curved, outer margin heavily curved; distal edge somewhat curved, linear shaped, slightly sclerotized in the middle; the weakly sclerotized “window” circa one and half times wider as high, trapezoidal with a double, wider, sclerotized streak proximally. 8 th tergite as high as wide, bellshaped; proximal edge trapezoidal, distally much wider than proximally, its lateral sides angled distally; lateral sides heavily curved, proximally thick, linear, distally triangular widening; distal edge curved, angled in the middle, weakly sclerotized; the weakly sclerotized “window” as wide as high, rather rhomboidal. Female genitalia ( Figs 25, 26 ). Ovipositor rounded shaped, slightly longer as wider; papillae anales weakly sclerotized, oval, flattened, densely hairy; apophyses anteriores shorter than apophyses posteriores; ostium oval; antrum moderately sclerotized, wide, plate-like. Ductus bursae moderately long, distally conspicuously narrower, angled curved; distal part narrower than the proximal part, the latter weakly sclerotized with some weakly sclerotized crests. Corpus bursae sac-like, rather straight, proximally rounded, fused with appendix bursae; appendix bursae tubular, helicoidal. Female 7 th abdominal segments ( Fig. 29 ). 7 th sternite as wide as high, trapezoidal, weakly sclerotized; proximal edge and lateral sides weakly sclerotized, hardly recognizable; distal edge somewhat more sclerotized, slightly curved with a short, flat, wide and less sclerotized “window” in the middle. 7 th tergite as wide as high, quadrangular, three-fourth part in semicircle slightly more sclerotized with a “U”-shaped, less sclerotized “window”; proximal edge and lateral sides hardly recognizable; distal edge angled curved. Between the sternite and tergite, distally with double, tuft of dense, short hairs. Etymology. The species is dedicated to Dr Hermann Höne ( 1883–1963 ), the famous German entomologist, who lived for a long time in China and extensively collected with his Chinese collectors huge amounts of moths and butterflies across China (about half a million of specimens are housed in the Lepidoptera collection of ZFMK).

Distribution map of Narcotica spp. Distribution ( Fig. 34 ). Narcotica hoenei was found only in Central (Prov. Shaanxi , Qin Ling Mts and Prov. Sichuan , Omisien) and eastern China (surrounding of Shanghai , Nanjing and Mt. Yingshan) with overlapping range of distribution with N . niveosparsa (with no sympatric occurrence) and with N . cryptica (however, in West Tien-mu-shan, the sympatric occurrence has not been confirmed yet).
