Capnogryllacris latilamargis sp. nov., Chinese name ṀỪffiḏ⁂

( Figs. 1 , 2 )

Description. Male. Body medium large. Head: Face ovoid, nearly smooth; fastigium verticis broader, about twice as wide as scapus. Eyes oval, ocelli indistinct. Second and third abdominal tergites on lteral areas without stridulatory pegs.

Wings surpassing apices of hind knees. Left tegmen ( Fig. 2A ): Radius gives rise to radius sector in the middle, both forked near tips; media anterior with a common stem with radius, arising after basal quarter; cubitus anterior forks before basal third into two veins, CuA1 and CuA2; media posterior arises at about basal third of tegmen from CuA1; cubitus posterior undivided, free throughout; with 4 anal veins, the fourth with common stem with third anal vein. Right tegmen ( Fig. 2B ): Cubitus anterior at base single branched, after division into two branches before end of basal quarter, the anterior branch makes a curvature and receives a short connection branch from MA, shortly after it divides into MP and CuA1, which are running parallel; CuA2 without further division; cubitus posterior undivided, free throughout; with 4 anal veins, the fourth with common stem with third anal vein. Legs: Fore coxa with a small spine at anterior margin; fore and mid femora unarmed on ventral surfaces, tibiae with 4 pairs of large ventral spines and one pair of smaller ventral apical spurs. Hind femur with 9–10 external and 6–7 internal spines on ventral surface; hind tibia with 6 pairs of spines on dorsal surface; with 2 pairs of ventral apical spurs and a pair of dorsal apical spurs. Eighth abdominal tergite prolonged ( Fig. 1D ). Ninth abdominal tergite split in the midline, the lateral areas of the median furrow semi-globularly swollen, at ventro-apical margin on both sides with acute spines and crossing each other ( Fig. 1F ). Cerci long conical, apices acute. Subgenital plate wider than long, posterior margin little concave. Styli inserted at apico-lateral angles, faintly curved dorsad.

Coloration. General color yellowish brown. Eyes black, clypeus and labrum light brown. Disc of pronotum along posterior margin with a broad black stripe ( Fig. 1C ), lateral lobes almost black ( Fig. 1B ). Wings yellowish brown, without color pattern, veins brown.

Female. Unknown.

Specimens examined. Holotype: male, Lidong mountain , Taoyuan, Taiwan, China, 16 August 2017, collected by Tian Xie. Other specimen: 1 male, Lidong mountain, Taoyuan, Taiwan, China, 4 September 2016, collected by Tian Xie.

Measurements (mm). Body: ♁ 31.5–32.0; pronotum: ♁ 6.0–6.2; tegmen: ♁ 33.0–36.0; hind femur: ♁ 14.8– 16.5.

Discussion. The new species differs from the known species of Capnogryllacris by the disc of pronotum along posterior margin with a broad black stripe, and the lateral lobes almost black.

Etymology. The name of the new species refers to posterior margin of pronotum with a broad black stripe, lateral lobes almost black; from Latin latil- (broad) and marg- (margin).
