Neowuia wuyishana Huo & Du, sp. nov.

Figs. 1–5

Adult habitus. General color dark brown (Fig. 1A). Head mostly pale brown except the frontocylpeus area and ocellar triangle with dark pattern (Fig. 1B–C). 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). Legs dark brown (Fig. 1A). Wings hyaline, veins dark brown, typical of this genus (Fig. 1D–E).

Male. Forewing length 10.7 mm, hindwing length 9.1 mm, body length 10.0 mm. Abdomen brown (Figs. 2–3). Terga 1–6 with paired dark round dots laterally (Fig. 2A). 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, 3A). 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 plus inset). The vesicle of sternum 7 developed, large, and semicircular (Figs. 2B, 3B). Epiproct connected to tergum 10 only by membranous tissue; epiproct sclerite (Fig. 4A–B) 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). Subgenital plate broadly triangular (length:width ratio approximately 1:2.8), slightly sclerotized (Fig. 5A–B).

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). Anchor semicircular, without massive stem, sparsely covered with several small globular bodies (Fig. 5D).

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. Huo Qing-Bo, Zhao Meng-Yuan, Zheng Wu.

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), the large anchor with “X” shaped terminal on tergum 10 (Fig. 3C), 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).

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