Diagnosis. Adult (Figs 5–8, 30B). Narcotica cryptica differs from N. hoenei by its larger size (wingspan 26–28 mm in N. cryptica and 19–23 mm in N. hoenei), conspicuous, whitish orbicular spot and whitish patch in the apical region of the forewing, less contrasting medial fascia, and the blackish crest dorsally on the abdomen. The species can be distinguished from both congeners by the somewhat variegated, rather mottled forewing pattern and the presence of a lighter, greyish patch between the antemedial- and medial lines of forewing (Fig. 30).
Male genitalia (Figs 14, 15, 31B, 32B). The new species has, in comparison with N. niveosparsa, slightly straighter, less protruding harpe, somewhat wider opened clasping apparatus (Fig. 31), less parallel, proximally more curved carina field of aedeagus and different armature of the vesica having somewhat longer and larger cornuti basally, slightly longer cornuti medially and more numerous medium-sized cornuti distally on the surface of the larger distal diverticulum (Fig. 32). Comparing with N. hoenei, N. cryptica has larger clasping apparatus and vesica, more protruding harpe, and wider carinal field of aedeagus. The structure of the vesica is also different as the armature of N. cryptica is more complex, consisting of 10–12 medial cornuti of larger size, and more numerous medium-sized cornuti distally with stronger cornuti at the terminal section; in addition, the basal and terminal diverticula are more prominent in N. cryptica than in N. hoenei.
Male 7 th and 8 th abdominal segments (Fig. 19). This species has more trapezoidal 7 th sternite with straight lateral sides, wider 7 th tergite with more curved lateral sides, slightly narrower 8 th sternite with more rectangular “window”, and less reduced posterior abdominal brush, substituted by more sclerotized, split streak than in N. niveosparsa; straighter distal edge of 7 th sternite, wider 7 th tergite, somewhat higher and narrower 8 th sternite with more rectangular “window”, and slightly reduced posterior abdominal brush, substituted by a thinner, split streak than in N. hoenei. N. cryptica has wider, bell-shaped 8 th tergite with slightly narrower distal part; more curved lateral sides with smaller bulb-like or smaller, isosceles triangle-like distal end and larger, oval “window” with wide handle-like part in the middle-distal section or more irregular shaped, oval “window” than in N. niveosparsa; slightly wider, bell-shaped 8 th tergite with longer, more triangular distal part, lateral sides with smaller bulb-like or smaller, isosceles triangle-like distal ends and larger, oval “window” with wide handle-like part in the middle-distal section or more irregular shaped, oval “window” than in N. hoenei. The size of the abdominal segments is equal with those of N. niveosparsa but is larger than those of N. hoenei.
Female genitalia (Figs 23, 24, 33B). The new species has similar structure of genital capsule to its congeners, however, it has slightly shorter distal part of ductus bursae and somewhat wider junction of ductus bursae to corpus bursae and longer, somewhat straighter corpus bursae. In N. cryptica, the transition of ductus bursae to corpus bursae is more angled (Fig. 33) than in N. niveosparsa and N. hoenei. In N. cryptica, the entire organ is much larger than that of N. hoenei.
Female 7 th abdominal segments (Fig. 28). There is no significant difference among the three Narcotica species, since the size of the “window” on the tergite is variable. The size of the abdominal segments in N. cryptica is equal with that of N. niveosparsa but larger than in N. hoenei.

Ovipositor rounded shaped, slightly longer than 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 sack-like, angled compared to ductus bursae, proximally slightly pointed, fused with appendix bursae; appendix bursae tubular, helicoidal.
Female 7 th abdominal segments (Fig. 28). 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 “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 name “ cryptica ” refers to the late recognition of the species due to the high similarity of its congeners, especially to N. niveosparsa.
Distribution (Fig. 34). Narcotica cryptica is distributed in the southern part of South Korea and the mainland of China, with overlapping range of distribution with N. niveosparsa (however, the specimen from the Wuyi Mountains was collected only 50 km far from the collecting site of one of the specimens of N. niveosparsa) and N. hoenei but with no sympatric occurrence. In West Tien-mu-shan, both N. cryptica and N. hoenei occur, however, their sympatric distribution has not been confirmed yet.
Notes. The Korean and Chinese populations show some size differences in the male vesica and female corpus bursae, however, to answer whether these morphological differences are taxon differential requires additional material and detailed analysis. The variance in the number of basal and medial cornuti is also not known entirely.
