Type materials.

Holotype. China: Male, Guangxi, Longzhou, Nonggang National Nature Reserve, bush leaves, 2.X.2021, 22.46°N, 106.96°E, Zhixin He & Ning Wang, sweep net, leg. Paratypes. 1 male, 2 females, same data as holotype (SNNU).

Description.

Male (Figs 5A , 6A , 7A, C, E, G ). Body size small. Head small, slightly broader than anterior of pronotum. Frons as wide as antennal scape. Eyes large and protruding laterally. Three apical joints of maxillary palpi distinctly elongate, and the fifth joint apically truncated. Pronotum transverse, posterior margin broader than the anterior one. Tegmen extending over abdominal apex, and bearing six staggered primary veins with many transverse veins between them. The visible part of hindwing half length of tegmen. Internal tympanum large and long-oval, and external one shaped like a small pit. The hind tibia bears three dorsal spurs on each side.

Genitalia (Fig. 8A-C ). Lateral lobes of epiphallus stick-like, apically blunt, and inward curved in dorsal view. Ectoparamere roughly rectangular with the marginal part sclerotized and the remainders membranous. Ectophallic and endophallic apodemes short and not surpass rami.

Female (Figs 5B , 6B , 7B, D, F ). Resembles male but slightly smaller. Longitudinal veins of tegmen parallel and producing rectangular cells (fill with dark brown) with a few pale transverse veins. Ovipositor not surpassing hindwings. Dorsal and ventral margins of the basal of ovipositor smooth and faintly narrowing, and both margins of apical part slightly denticulated and apically curved upwards.

Coloration. Body yellowish-brown. Pronotum dark brown. Most of the fore and middle femur darkly colored, but with apex pale. Hind femur medially bears a dark brown band. Tarsus darkly colored. Cercus black and white.

Measurements. Male: BL 5.68-5.93, PL 0.82-0.91, TL 4.22-4.64, HFL 3.82-4.21. Female: BL 5.87-6.21, PL 0.76-0.82, TL 4.21-4.43, HFL 4.07-4.33, OL 2.25-2.51.

Etymology.

The name refers to the province of China where the type locality is located.

Distribution

(Fig. 1 ). China (Guangxi).

Remarks.

This species is similar in appearance to F. fujianensis and F. denutilatus but differs in its squared ectoparamere (that of F. fujianensis is round) and blunt apex of epiphallic lateral lobe (that of F. denutilatus is acute). The transverse cells of female tegmen of the new are more darker than that of F. fujianensis .
