Figs. 1–2 View FIGURE 1 View FIGURE 2
Description. Male. Face ovoid; forehead nearly smooth with some scattered impressed; fastigium verticis about 1.4 times as wide as scape ( Fig. 1A View FIGURE 1 ). Ocelli very distinct, light yellow; median ocellus slightly larger than lateral ocelli ( Fig. 1A View FIGURE 1 ). Anterior margin of pronotum slightly projected in the middle, posterior margin almost truncate with median concavity; lateral lobes longer than high ( Fig. 1B View FIGURE 1 ). Fore coxae with 1 spine. Fore and middle femora unarmed, hind femora with 3–4 internal and 6 external spines on ventral surface. Fore and middle tibiae with 5 ventral spurs on both sides on ventral surfaces, including one pair of apical spurs; hind tibiae with 7–8 internal and 8 external spines on dorsal surface, ventral surface with 1 pair of subapical spurs, apices with 1 pair of dorsal and 2 pairs of ventral spurs. Tegmina surpassing the apex of abdomen ( Fig. 2A–B View FIGURE 2 ). Tegmen ( Fig. 2C–D View FIGURE 2 ): radius with two branches: both forked near tip; MA has a common stem with radius, arising as first posterior branch of radius before basal third; media posterior absent; cubitus anterior forks before basal third into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common base. Second and third abdominal tergites with two rows of stridulatory pegs separately ( Fig. 1D View FIGURE 1 ). Eighth abdominal tergite prolonged ( Fig. 1E View FIGURE 1 ). Ninth abdominal tergite projecting backwards, forming an angular ( Fig. 1E View FIGURE 1 ), the apical half curved ventrad and split along the midline, both sides swollen and terminating into a small process on ventral margin, ventral surface of the process with one slender spine one each side ( Fig. 1F–G View FIGURE 1 ). Cerci slender, apices subacute. Subgenital plate wider than long, posterior margin with rectangular lobe and ventral surface of the lobe with obviously median carina ( Fig. 1H–I View FIGURE 1 ). Styli inserted on the lateral area of posterior margin of subgenital plate.
Female. Unknown.
Coloration. General color yellowish brown. Face, genae and labrum reddish brown ( Fig. 1A View FIGURE 1 ). Ocelli pale yellow ( Fig. 1A View FIGURE 1 ). Mandibles black. Pronotum with darker margins ( Fig. 1B View FIGURE 1 ). Tegmina light brown. Dorsal surface of abdomen medium or reddish brown.
Measurements (mm). Male: BL 22.7, PL 5.1, TL 21.9, HFL 12.0.
Material examined. Holotype: male, Yiwu, Mengla , Yunnan, November 6, 2021, coll. by Ping Yang.
Distribution. Yunnan (Mengla).
Discussion. The new species differs from other Ocellarnaca species in: body slender, median ocellus smaller than congeneric species, about as large as lateral ocelli ( Fig. 1A View FIGURE 1 ); male ninth abdominal tergite split along the midline, both sides swollen and terminating into a small process on ventral margin, ventral surface with one slender spine one each side ( Fig. 1F–G View FIGURE 1 ); posterior margin of male subgenital plate with rectangular lobe and ventral surface of the lobe with obviously median carina ( Fig. 1H–I View FIGURE 1 ).
