Type material. CHINA, Shaanxi: Holotype ♂, Mt. Hua, VII.1979, leg. C Tian & T Chen, slide No. SH 19156. Paratype: 1♂, same data as holotype, slide No. SH 20233.
Diagnosis. The new species is similar to N. staudingerella (Christoph, 1881) in the forewing pattern. It can be distinguished in the male genitalia by the inverted heart-shaped uncus, the sacculus reaching near the middle of the ventral margin and the phallus without a sclerotized belt. In N. staudingerella, the uncus is subtriangular, the sacculus reaches near the apex of the ventral margin, and the phallus has a pair of sclerotized belts from distal 1/4 to 1/10.
Description. Adult (Fig. 17). Male wingspan 22.5−23.0 mm.
Head: Vertex pale yellow; frons purplish brown. Eye interocular index 0.50−0.52. Proboscis brown. Labial palpus 1.5−1.6 × vertical eye diameter; first and second tarsomeres pale yellow, with black hairs; third palpomere brown. Antenna 3.7−4.0 × length of forewing; scape dark brown; flagellum grayish brown except dark brown in basal 1/5.
Thorax: Mesonotum golden yellow except pale yellow laterally; tegula bronzy yellow. Forewing ground color yellow from base to inner fascia, grayish brown with golden luster from beyond outer fascia to apex, darker and with dense black scales between costal margin and R 4 distally; black rectangular speckle at base between Sc and R 1, brown streak from base to middle along costal margin, edged with black scales; four black lines: first line from base to 2/5 of wing along R 1, second line from base to 2/5 of cell along anterior margin, third line from near base to beyond 2/5 of wing along CuP, fourth line from base to 1/5 along dorsum; inner and outer fasciae silvery gray, edged with black scales, inner fascia slightly curved inward, outer fascia almost straight, medial fascia yellow, slightly curved inward; brownish yellow fascia from near distal 1/4 of costal margin to beyond tornus, edged with black scales; fringe brown. Hindwing grayish brown except light brown between costal margin and Rs; fringe brown. Foreleg with coxa dark purplish brown, femur and tibia brown, tarsus yellow; mid- and hindlegs yellow. Epiphysis brown, at basal 2/5 of tibia, not reaching apex of tibia.
Abdomen: Dark brown.
Male genitalia (Fig. 40). Socius ovoid, length 1.6 × width. Tegumen with distinct median ridge. Uncus inverted heart-shaped. Valva fused for basal 1/3, rounded at apex, straight on costal margin, obliquely straight on ventral margin; sacculus subtriangular, reaching near middle of ventral margin. Transtilla with a triangular anterior emargination medially, produced anterolaterally, straight on posterior margin; median process small, spiniform, slightly beyond posterior margin apically. Vinculum 3.2 × length of valva, obtuse anteriorly. Phallus slightly longer than vinculum, with spines from distal 2/5 to near apex and with a belt of short spines in distal 1/6; vesica with denticles (Fig. 40a). Juxta 0.60 × length of phallus; lateral arm 0.18 × length of arrow head.
Female unknown.
Distribution. China (Shaanxi).
Etymology. The specific epithet is derived from the Latin parvus and processus, referring to the small median process of the transtilla.
