NEFU.</p><p><b>Diagnosis.</b> For males, <i>N. shennongshii</i> <b>sp. nov.</b> (Figs 1, 7) is similar to <i>N. taurina</i> (Figs 3, 8) and <i>N. stueningi</i> in appearance (Figs 5, 9), but can be distinguished from them by certain features of the forewing markings and ground color. Unlike <i>N. taurina</i>, the new species has a conspicuously narrower median area and lacks the distinct black definition of the antemedial and postmedial lines; the upper section of the postmedial line is almost straight, touching the outer edge of the reniform stigma, while it is running far from it in <i>N. taurina</i> producing a wide outcurve at the lower extremity of the cell. <i>N. shennongshii</i> differs from <i>N. stueningi</i> in its generally lighter colouration on both wings, with silvery-grey suffusion of the forewing median area which is lacking in <i>N. stueningi</i>.</p><p>In the male genitalia, the socii of <i>N. shennongshii</i> <b>sp. nov.</b> are broad at the base and hooked at the apex, whereas slender and thorn-shaped in <i>N. taurina</i>, and club-shaped in <i>N. stueningi</i>. The saccular process in the new species is apically pointed triangular, while it is more basally positioned, short, and narrow trapezoidal in <i>N. taurina</i>; this saccular process is rounded triangular in <i>N. stueningi</i>.</p><p>For females, <i>N. shennongshii</i> <b>sp. nov.</b> (Figs 2, 10) is very similar externally to <i>N. taurina</i> (Figs 4, 11) and resembles <i>N. bacsovi</i> (Figs 6, 12). <i>N. shennongshii</i> and <i>N. taurina</i> are hardly distinguishable by the colouration and wing pattern, displaying only slight differences: the subbasal line of the new species is darker than that of <i>N. taurina</i>; the basal line of the new species is more obscure than that of <i>N. taurina</i>, and its inner area lacks a distinct dirty white color; the antemedial line in the new species is more serrated compared with that of <i>N. taurina</i>; the postmedial line in the new species is somewhat more convex at veins M 1 and A 1+2 than in <i>N. taurina</i>, but the female genitalia display clearly recognizable differences. Both closely related species differ from <i>N. bacsovi</i> by their smaller size, less darkened basal and marginal areas, narrower median area bordered by sharper blackish antemedial and postmedial cross-lines, and paler, more uniformly greyish hindwings.</p><p>In the female genitalia, the antrum of <i>N. shennongshii</i> <b>sp. nov.</b> is saddle-shaped, this part of the copulatory organ is funnel-shaped in <i>N. taurina</i> and bell-shaped in <i>N. bacsovi</i>. The ductus bursae is wider in the new species than in <i>N. taurina</i> and <i>N. bacsovi,</i> with the narrowest in <i>N. bacsovi</i>. The tubular part of the corpus bursae in the new species is curved at the top and has a single coil; while in <i>N. taurina</i>, this section is relatively longer and coils twice.</p><p><b>Description. Male. Adult</b> (Fig 1). Forewing length 17 mm, wingspan 36 mm. <b>Head</b>. Grey; labial palpus dark brown; antennae shortly bipectinate. <b>Thorax</b>. Densely covered with grayish white hair, mixed ochre; patagium whitish black; tegula white gray. Forewing wide; basal line black, visible only at the costal margin; subbasal line wavy, dark grey; antemedial area slightly lighter than ground color, obscure; antemedial line double, its inner line dark grey, broad and distinct, outer line grayish-brown, thin and indistinct, protruding at vein Cu 2; median area white-gray, with an inverted triangle black mark near the costal margin; median line absent; postmedial line double, wavy, with the inner line being faint, finely touching reniform stigma; subterminal line silvery white, poorly visible; terminal line black; fringes as ground color; orbicular stigma absent; reniform stigma kidney-shaped. Hindwings paler than forewing, pale whitish-grey; veins distinct; marginal area light gray; median line thin, grayish-black; terminal line blackish; fringes as ground color.</p><p><b>Abdomen.</b> Brown, mixed with pale scales.</p><p><b>Female</b> (Fig 2). Forewing length 18 mm, wingspan 38 mm. Similar to male, but antennae filiform; antemedial area prominently broader and lighter than that of the male, antemedial line double, zigzagged; median area white-gray; median line absent; postmedial line more convex at veins M 1 and A 1+2.</p><p><b>Male genitalia</b> (Fig 7). Saccus well-developed. Vinculum wide, strongly sclerotized. Fultura superior slightly sclerotized, bar-shaped. Tegumen rather short and broad. Uncus wide at base, straight in the middle part, tapering and rounded apically; socii broad at base, hooked at apex. Juxta V-shaped, slightly sclerotized. Valva narrow, slightly sclerotized, parallelogram-shaped; sacculus thick, shorter than half the length of valva, with small triangular saccular process, sclerotized; costa broadly sclerotized. Aedeagus long, narrow, strongly sclerotized, slightly curved medially, dagger-shaped, with long ventral carinal process and rather narrow distal opening; vesica tubular, tapering distally with tiny sclerotized cornuti.</p><p><b>Female genitalia</b> (Fig. 10). Papillae analis short, wide, sclerotized, covered in sparse short setae; apophysis posterioris and apophysis anterioris strongly sclerotized, with the former being 3/4 the length of the latter; ostium bursae saddle-shaped; antrum strongly sclerotized, saddle-shaped; ductus bursae short, membranous; tubular distal part of corpus bursae with one full coil; proximal part of corpus bursae oblong, weakly sclerotized.</p><p><b>Distribution.</b> China (Hubei).</p><p><b>Etymology.</b> The species name is dedicated to “Shennongshi”, who was the leader of the Jiang tribe in ancient China.
