( Figs. 1–7 View FIGURES 1 – 7 )
Diagnosis. This species is characterized by the presence of several anterolateral spots and medially with two dark brown lobes of pigmentation on tergum eight. Its epiproct is nearly rectangular and recurved; dorsal sclerite has two darkly sclerotized basolateral bands and a pair of two darkly sclerotized, medial sclerites forming three proximal spines in dorsal view.
Male: Forewing length 5.3 mm, hind wing length 4.6 mm. Head and compound eyes dark, antennae and mouthparts dark brown, maxillary palpi yellowish brown. Thorax brown, pronotum rectangular but posterior margin concave, surface rugose, with obtuse corners; legs brown. Wings subhyaline, veins dark brown. Abdomen brown; hairs on abdomen mostly pale.
Terminalia ( Figs. 1–7 View FIGURES 1 – 7 ): Tergum eight sclerotized but posteromedially membranous, anterolaterally with several dark rounded spots and medially with two dark brown lobes of pigmentation. Tergum nine with broad anterior indentation, many tiny spines on a sclerotized plate medially and row of long bristles paramedially located along posterior margin. Vesicle on sternum nine claviform, distal half dark brown, slightly swollen subapically; hypoproct rounded basally, gradually narrowing medially toward tip but abruptly tapering subapically. Tergum ten weakly sclerotized except posterolateral margins mostly sclerotized, a narrow longitudinal concavity present anterior to base of epiproct, many spinules located along anterolateral margins of the concavity. Cercus sclerotized, with an outcurved subapical spine and a tiny proximal spine. Epiproct nearly rectangular and recurved; dorsal sclerite mostly sclerotized, with two darkly sclerotized basolateral bands and a pair of two darkly sclerotized, medial sclerites forming three proximal processes in dorsal view, subapical portion bearing two curved lateral sclerites which are extended into two apical blunt spines, tip of dorsal sclerite triangular in dorsal view but quadrate in lateral view; ventral sclerite strongly sclerotized, fringed with a row of tiny ventral spines. Paraproct divided into two lobes: outer lobe sclerotized with anterolateral portion distinctly sclerotized, broad at base, strongly upcurved subapicaly, forming a large hook in lateral aspect, its proximal margin with tiny spines when dorsally viewed; inner lobe sclerotized, narrow and sinuous, nearly as long as outer lobe.
Female: Unknown.
Type Material. Holotype: male, CHINA: Henan Province, Song County, Mt. Baiyunshan, 1500 m, 34.7156 N, 111.8678 E, 2008. VIII. 17, K.Y. Zhang.
Distribution. China (Henan).
Etymology. The species is named after its type locality, Mt. Baiyunshan.
Remarks. A prominent hook-shaped process on the outer lobe of paraproct also appears in N. stellata Li and Yang, 2008 from Sichuan, but the new species lacks the large upraised star-like projection of the tergum 10 that distinguishes N. stellata (Figs. 16 & 21 in Li and Yang 2008a).
