Diagnosis: This species is similar to N. mesoplaca by having an inconspicuous gnathos in the male and the absence of spiculose ring in the female, but can be distinguished easily from it by the uncus arms joined with each other only at base, the valvae bearing one large dorsoapical and one small ventroapical processes, and the phallus articulated at basal 1/6. In N. mesoplaca , the uncus is fully fused medially, the valvae carry one large ventroapical process only, and the phallus is articulated at about 3/5.
Adult ( Fig. 6 View FIGURES 1 – 8 ): Wingspan 11.0–12.0 mm. Head ocherous white. Labial palpi with inner side ocherous white, outer side dark brown, third segment ocherous yellow to ocherous white apically. Antennae with scape ocherous white, flagellar segments ocherous gray. Thorax and tegulae ocherous white to ocherous yellow except tegulae dark brown on anterior margin. Forewings ocherous yellow, with scattered white scales; costal margin with a short dark brown transverse band extending from 1/2 to midwing, with four small dark brown spots at base, 1/4, 2/3 and subapex; small conspicuous or inconspicuous dark brown dots scattered along costal and dorsal margins; cilia ocherous yellow, sparsely mixed with dark brown. Hindwings and cilia grayish white to gray.
Male genitalia ( Fig. 14 View FIGURES 13 – 15 ): Tegumen separated from uncus, anterior and posterior margins more or less straight. Uncus arms joined with each other at base by membrane; basal half broad, triangular; distal half digitiform, covered with coarse hairs, obtusely pointed at apex. Gnathos being a small sclerite. Subscaphium narrow, band-shaped. Valvae somewhat trapeziform, bearing one large dorsoapical thorn and one small ventroapical toothlike process, both greatly sclerotized; digitiform processes narrowed slightly at base, broadened gradually to middle, then narrowed gradually to pointed apex, slightly exceeding apex of valvae. Vinculum with posterior margin convex at middle, anterior margin arched slightly. Saccus about 1.25x length of valvae, rod-shaped, obtusely pointed at apex. Juxta large, inverted triangular, basal 3/4 heavily sclerotized, distal 1/4 weakly sclerotized; with two small sclerotized rhombic structures at center. Phallus about 2.7x length of valvae, curved slightly, articulated at about 1/6, with one sclerotized spiny subapical process.
Female genitalia ( Fig. 20 View FIGURES 16 – 20 ): Abdomen sternum VIII sclerotized anteriorly, with a rod-shaped median process protruding backwards to 1/2, its apex with two long hairs. Ostium bursae inconspicuous. Antrum somewhat columniform, weakly sclerotized, wrinkled transversely, narrowed and sclerotized anteriorly, with lepidotic microtrichia near anterior sclerite. Ductus bursae about 3.0x length of apophyses anteriores, without spiculose ring.
Distribution: China (Henan).
Etymology: The specific name is derived from the Latin bidentatus (= bidentate), in reference to the two dentate apical processes of the valvae.
