Figs. 2, 6
Types. Holotype: ♂, Mt. Jiulong (28°21' N, 118°52' E), Zhejiang Province, 5.VIII.2011, alt. 400m, leg. Linlin Yang and Na Chen, genitalia slide no. YHL12014. Paratypes: 8♂, Badagongshan (29°45' N, 109°41' E), Hunan Province, 13.VIII.2001, alt. 1250m, leg. Houhun Li and Xinpu Wang.
Diagnosis. This new species is very similar to N. nipponica Oku, 1974 in the male genitalia. It can be separated easily from the latter species by the presence of an uncus, and by the narrow sacculus lacking a ventral prominence. In N. nipponica, the uncus is absent, and the valva has a small ventral projection on sacculus. In addition, the hindwings of this new species bear black scent scales on the underside; whereas in N. nipponica the modified scent scales are absent on the hindwings.
Description. Adult (Fig. 2). Head: Vertex rough scaled, fuscous. Antenna fuscous. Labial palpus ascending; median segment not expanded; terminal segment blunt.
Thorax: Fuscous, except basal part brown; posterior crest distinct. Legs white; hind tibia in male normally scaled, with one white hair pencil at base. Forewing length 8.0–9.0 mm; costa expanded basally, concave on midlength and proximal to apex; apex blunt; termen oblique; costal strigulae one and two leaden, distal seven pairs apricot, with leaden striae; basal fascia and subbasal fascia black, lower parts of them confluent, distal edge straight and reaching base of dorsum; striae from strigulae one and two distinct, extending backward to base of dorsum; strigulae three and four confluent, their extension forming an elongate ovate spot, apricot, dusted with ochreous lines, upper edge between 1/5 length and 3/7 length of costa, distal edge extending obliquely along outer edge of cell to 1A+2A, with ochreous margin between costa and cell, lower edge between 1/3 length and 3/4 length of 1A +2A; leaden striae between spot and dorsum; median fascia black, indicated by a small patch on costa and sparse dots on cell; strigulae five and six short, striae from them distinct, separated by an ochreous suffused with black narrow stripe, proximal pair extending beyond 1/5 length of R1 and base of M3, and reaching distal part of dorsum, distal pair extending beyond 2/5 length of R1 and midlength of M3, and reaching tornus, leaden suffused with silvery below M2; postmedian fascia black, narrow between costa and midlength of R4 and with ochreous margin, broadened backward, reaching area between midlength of M2 and termen, lower part ochreous, confluent with strigula six, forming a pale spot; striae of strigulae seven and eight confluent below costa, then meeting with stria from strigula nine on 3/4 length of R5; preterminal fascia a short line, black suffused with ochreous, reaching distal part of M1; terminal fascia indistinct; a leaden streak extending from apex to distal part of M2; a black line along termen between R5 and M3; cilia on apex and termen black suffused with ochreous, ochreous on tornus; underside pale fuscous except fasciae and fold fuscous, costal strigulae and the area of hindwing overlapping white. Hindwing upperside pale fuscous, the area of forewing overlapping white; cilia pale fuscous, with fuscous baseline; underside pale fuscous, white between costa and cell; fuscous on basal half of CuA2; an ovoid area between dorsal fold and dorsum covered black scales.
Abdomen: Male genitalia (Fig. 6) with uncus a short hook. Socius drooping, rectangular, covered with long hairs. Valva neck short, naked; sacculus narrow, covered with short spines; cucullus about half of valva in length, densely covered with spines, basal part slightly protruding ventrally and the prominence blunt, a list of short thorns arranged along ventral edge. Phallus moderate in length, basal part broad, narrowed to apex, pointed apically; cornuti absent.
Etymology. The specific name is derived from the Latin sparsulus (= sparse) in reference to sparsely spined sacculus in the male genitalia.
