Figs. 1–5 View FIGURE 1 View FIGURE 2 View FIGURE 3 View FIGURE 4 View FIGURE 5

Adult habitus. General color dark brown ( Fig. 1A View FIGURE 1 ). Head mostly pale brown except the frontocylpeus area and ocellar triangle with dark pattern ( Fig. 1B–C View FIGURE 1 ). Triocellate, anterior ocellus smaller than posterior ones. Antennae and palpi dark brown. Pronotum disc rectangular (length:width ratio approximately 1:1.4), black laterally and dark brown medially; rugosities present laterally ( Fig. 1B–C View FIGURE 1 ). Legs dark brown ( Fig. 1A View FIGURE 1 ). Wings hyaline, veins dark brown, typical of this genus ( Fig. 1D–E View FIGURE 1 ).

Male. Forewing length 10.7 mm, hindwing length 9.1 mm, body length 10.0 mm. Abdomen brown ( Figs. 2–3 View FIGURE 2 View FIGURE 3 ). Terga 1–6 with paired dark round dots laterally ( Fig. 2A View FIGURE 2 ). Terga 8–9 bearing paired patches of sensilla on the posterior margin; terga 7–10 more sclerotized; tergum 8 with a large semicircular extension covered by long fine hairs at the median posterior margin; tergum 9 slightly sclerotized except the posterior margin ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ). Tergum 10 with paired dense sensilla basiconica patches on anterior margin, without hemiterga but with a slim basal anchor medially; the anchor pointed in front and becomes larger “X” shaped extending in terminal ( Figs. 3C–D View FIGURE 3 plus inset). The vesicle of sternum 7 developed, large, and semicircular ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ). Epiproct connected to tergum 10 only by membranous tissue; epiproct sclerite ( Fig. 4A–B View FIGURE 4 ) consists of an oval closed ring with an upper, longitudinally bridge-jointed arm, and its tip ends of a strong beak-like extending. The paragenital plate is as triangular lobe, medially more sclerotized in dorsal view, inner lobes membranous and bearing large scales on the surface. Aedeagus membranous, without visible sclerite or spines.

Female. Forewing length 10–11 mm, hindwing length 9.0– 9.5 mm, body length 10–11 mm. Body coloration similar to male ( Fig. 1A, C View FIGURE 1 ). Subgenital plate broadly triangular (length:width ratio approximately 1:2.8), slightly sclerotized ( Fig. 5A–B View FIGURE 5 ).

Egg. 303.9 µm wide, 449.8 µm long. Turtle shaped, with one longitudinal dorsal ridge. Surface smooth and without visible micropyle or papillae. Collar 131.6 µm wide, present on the ventral position, with obscure papillae covered ( Fig. 5C–D View FIGURE 5 ). Anchor semicircular, without massive stem, sparsely covered with several small globular bodies ( Fig. 5D View FIGURE 5 ).

Nymph. Unknown.

Type material: Holotype: 1♁, China: Fujian Province, Wuyishan City, Mount Wuyi, Sangang , 2009-VI-1, leg. Xue Hai-Yang. Paratypes: 3♀♀, same locality and data as the holotype ; 4 ♀♀, Wuyishan City , Mount Wuyi , from Tongmu Bridge to Yiliping (approximately 1 km from Sangang), 690m, 27.73512°N, 117.68541°E, 2021-V-14, leg.

Distribution. China (Fujian).

Etymology. The scientific name refers to Mount Wuyi (=Wuyishan), the type locality.

Diagnosis. The new species can be distinguished from N. qinlinga by a combination of the large semicircular extension covered by hairs on tergum 8 ( Fig. 2A View FIGURE 2 ), the large anchor with “X” shaped terminal on tergum 10 ( Fig. 3C View FIGURE 3 ), the sclerite of epiproct consisting of a closed ring with longitudinally bridge-jointed arm and a beak-like extension, and the inner lobes of paragenital plate with large scales ( Fig. 4 View FIGURE 4 ).

Remarks. This species lives on the vegetation adjacent to large rivers in Mount Wuyi ( Fig. 6A View FIGURE 6 ). Adults exhibit phototaxis at night, since they were collected only on the light trap ( Fig. 6B View FIGURE 6 ). The type locality of this species is more than 1100 km away ( Fig. 6C View FIGURE 6 ) from the Qinling Mountains/ Sichuan Province, while they are mainly separated by Dabie Mountains and Wushan Mountains.
