Type material.
Holotype: China • 1 ♂; Guangxi Province, Guilin City, Yanshan District, Wangjia Village, Baigu Cave; 25°13.85'N, 110°20.52'E; 162 m; 1 November 2023, Hao-fei Fan leg; ZSCTC - LI 0001. Paratype: China • 9 ♂; same data as for holotype; 14 March 2024, Ting-Ting Li leg; ZSCTC -LI-0002 - LI-00010 • 8 ♀; same collection data as for preceding; 14 March 2024, De-Xing Liu leg; ZSCTC -LI-00011 - LI-00018 • 6 nymphs; same collection data as for preceding; 14 March 2024, Ting-Ting Li leg; ZSCTC -LI-00019 - LI-00024 • 1 ♂; Guangxi Province, Guilin City, Xiangshan District, Guilin National Forest Park in Guanxi; 25°13.93'N, 110°13.92'E; 148 m; 18 March 2024, Hao-fei Fan leg; ZSCTC -LI-0025 • 1 ♂; Guangxi Province, Guilin City, Diecai District, Baiyun Temple, 25°18.75'N, 110°22.38'E; 526 m; 28 March 2024, Hao-fei Fan leg; ZSCTC -LI-0026 • 1 ♀; same collection data as for preceding; 28 March 2024, Hao-fei Fan leg; ZSCTC -LI-0027
Diagnosis.
The absence of a specialized abdominal tergal gland places the new species into the simoni species group. This species is similar to N. baumi Lucañas, Blaha, Rahmadi & Patoka, 2021, N. bolivari Chopard, 1950, N. brooksi Roth, 1995, N. cockingi Trotter, McRae, Main & Finston, 2017, N. gonzalezi Lucañas & Lit, 2016, N. leleupi Chopard, 1966, N. quartermaieni Trotter, McRae, Main & Finston, 2017, and N. termitophila Silvestri, 1946 as all these species are apterous. It can be distinguished by its eyes reduced to a few ommatidia narrowly grouped near antennal sockets (Fig. 3 D), while in N. baumi, N. bolivari, and N. cockingi eyes are absent. In addition, the tegmina of this species are distinctly longer than the end of the abdomen, while in N. brooksi, N. gonzalezi, N. leleupi, N. quartermaieni, and N. termitophila tegmina do not extend beyond the end of abdomen.
Measurements (mm).
Male, pronotum: length × width: 0.80–1.01 × 1.09–1.30, tegmen: 2.29–2.32, overall length (including tegmen): 2.99–3.02, body length (the length from the tip of vertex up to the tip of abdomen): 2.85–3.35. Female, pronotum: length × width: 0.96–1.15 × 1.30–1.51, body length (the length from the tip of vertex up to the tip of abdomen): 3.16–3.67.
Description.
Small size. Nymphs whitish (Fig. 4 F), adult yellowish. Male. (Figs 3 A, B, 4 E). Head: vertex of head exposed; eyes reduced to a few ommatidia narrowly grouped near antennal sockets (Fig. 3 F); ocelli absent (Fig. 3 F). Pronotum suboval, both sides of posterior margin with weak invagination, anterior margin and lateral margin with 12 setae (Fig. 3 E). Tegmina and hind wings: tegmina extending beyond the end of abdomen (Fig. 3 A, B), veins reduced in number, densely pubescent (Fig. 3 H). Lateral portions of metanotum pubescent, somewhat produced, suggesting a wing surface, but this region not separated from metanotum. Legs: legs long and slender (Fig. 3 I). Anteroventral margin of front femur Type C 1 (Fig. 3 G); the first tarsus of the hind leg longer than the sum of the remaining tarsi; tarsal claws symmetrical and unspecialized (Fig. 3 L), arolium and pulvillus absent (Fig. 3 N). Abdomen and genitalia: abdominal tergal gland unspecialized. Supra-anal plate symmetrical, middle of the hind margin triangular concave. Cerci with 11 segments; ventral surface of segments without spinous setae (Fig. 3 J). Subgenital symmetrical, middle of the hind margin concave (Fig. 3 K). Style absent. Male genitalia: genital hook (L 3) elongate, ventral to hook with approximately 17 strong setae; accessory hook-like phallomere (L 4 N), apex short and with double-hook, heavily sclerotized; L 2 narrow, L 1 elongate, process long spine-like; R 1 membranous, distal capitate-like; R 2 sinuate protrusion of central part, surface with scale-like tubercles; R 3 membranous; R 1 H reduced, rounded margin (Fig. 3 M).
Female: Apterous (Fig. 4 C, D). Supra-anal plate triangular, transverse of hind margin, middle with U-shaped invagination. Subgenital lobate (Fig. 3 C, D). Cerci with 11 segments; ventral surface of segments without spinous setae.
Etymology.
The specific name baiguensis is derived from the cave called Baigu Cave (Fig. 4 A, B), which is the first collection site of this species.
Distribution.
China (Guangxi).
