Figures 1–2 View FIGURE 1 View FIGURE 2
Description. Male. Body medium.
Head. Face ovoid with impressed scattered dots; fastigium verticis about two times as wide as scapes, separated by a very fine suture from fastigium frontis ( Fig. 1A View FIGURE 1 ). Ocelli distinct, median ocellus slightly larger than lateral ocelli ( Fig. 1A View FIGURE 1 ).
Anterior margin of pronotum faintly projecting in middle, posterior margin nearly straight ( Fig. 1B View FIGURE 1 ); lateral lobes longer than high, anterior angle widely rounded, posterior angle rounded angular, ventral margin undulant, humeral sinus shallow ( Fig. 1C View FIGURE 1 ).
Legs. Fore coxae with 1 small spine; fore and middle femora unarmed, tibiae ventrally with 4 pairs of spurs and 1 pair of apical spurs; dorsal surface of middle tibiae with 1 internal spine. Hind femora with 4–5 internal and 3–8 external spines on ventral surface; dorsal surface of tibiae with 6 pairs of spines, apices with 1 pair of dorsal spurs (the internal apical spur longer than external one) and 2 pairs of ventral spurs, ventral surface with 1 pair of apical spurs ( Fig. 2E View FIGURE 2 ).
Tegmina and wings. Tegmina and wings longer, slightly surpassing the hind leg ( Fig. 2E View FIGURE 2 ); hind wings slightly longer than tegmina. Tegmen ( Fig. 2A, B View FIGURE 2 ): Radius with two branches, both forked near tip; media anterior free from base, but in basal area closely approached to R; cubitus anterior at base with a single branch that forks into two veins in about basal fourth, the anterior branch makes a curvature and receives a very short oblique connection vein from MA and shortly after divides again into two parallel branches, MP and CuA1, while the posterior branch (CuA2) does not divide further; cubitus posterior undivided, free throughout; with 4 anal veins, the last two with a common stem.
Abdomen. Second and third abdominal tergites each with two rows of stridulatory pegs ( Fig. 1D View FIGURE 1 ). Eighth abdominal tergite prolonged. Ninth abdominal tergite prolonged, strongly bent down from dorsal surface, vaulted in lateral view ( Fig. 1E View FIGURE 1 ); ventral margin arched ( Fig. 1G View FIGURE 1 ); baso-lateral surface on both sides with a rather large acute process, which curved outward from middle area ( Fig. 1H View FIGURE 1 ). Tenth abdominal tergite transverse, with 1 tubercular process in middle ( Fig. 1J View FIGURE 1 ). Subgenital plate wider than long; basal margin straight, lateral margins convex on baso-lateral areas and then converging; posterior margin with a U-shaped concavity, the lateral lobes with internal margin shorter than external margin, apical margin obliquely ( Fig. 1L View FIGURE 1 ). Styli short and depressed, apices truncate, inserted at apico-lateral margins of subgenital plate.
Female. Unknown.
Coloration. Body black. Fastigium verticis and fastigium frontis yellowish brown. Ocelli yellow. All tarsi yellow brown. Wings blackish. Pleura reddish yellow. Sterna with a longitudinal yellow stripe along the midline.
Measurements (mm). Male: BL 24.40, PL 5.50, TL 35.53, HFL 15.16.
Material examined. Holotype: male, Daweishan, Pinbian , Yunnan, June 9, 2024, coll. by Ziyi Yang.
Distribution. Yunnan (Pinbian).
Discussion. The new species differs from other species of Phryganogryllacris by body almost black ( Fig. 2E View FIGURE 2 ), posterior margin of male subgenital plate with 1 large U-shaped concavity in middle ( Fig. 1L View FIGURE 1 ).
Etymology. The new species is named for its black coloration.
