Apical areas of processes on male tenth abdominal tergite brown. Apical halves of spines and spurs on hind femur and tibia brown. Male. Ninth abdominal tergite slightly broad at base, gradually narrowing. Tenth abdominal tergite very short, the middle of posterior margin with a pair of long processes, curved ventrad, basal areas strongly curved outward, afterwards moderately incurved on the whole, horn-shaped, apical areas sclerotized, tips acute. Cerci long conical with apices rounded. Basal half of subgenital plate broad, apical half gradually narrowing, posterior margin with a U-shaped notch.

Body: ♁20.1–21.5; pronotum: ♁4.6–4.8; tegmen: ♁16.0–17.5; hind femur: ♁11.8– 12.0. Material examined. Holotype: ♁, Qimaba, Lvchun, Yunnan, 26 July, 2022, coll. Yanhao Duan and Jie Su. Paratype: 1♁, Qimaba, Lvchun, Yunnan, 25 July, 2022, coll. Yanhao Duan and Jie Su. Other specimens: 1♁, same data as holotype; 2♁, Wuliangshan, Jingdong, Yunnan, 9 August, 2022, coll. Yanhao Duan and Jie Su. Etymology. The name of the new species is derived from the processes on male tenth abdominal tergite moderately incurved over the whole length, horn-shaped, from Latin in- (inwards) and curv- (curved). Discussion. The new species is similar to Homogryllacris parcibrevipenna Liu, Lu & Bian, 2021 and Homogryllacris curvicauda Du, Bian & Shi, 2016, but it differs from the former in: wings comparatively elongate, almost reaching or slightly surpassing apex of abdomen; the processes on male tenth abdominal tergite moderately incurved on the whole, horn-shaped, apical areas straight in lateral view; basal half of male subgenital plate is of nearly equal width, narrowing in apical half, subapical area with styli. The new species differs from Homogryllacris curvicauda Du, Bian & Shi, 2016 in: the processes on male tenth abdominal tergite longer, curved ventrad; apical half of male subgenital plate narrower than basal half.

Styli cylindrical and short, apices rounded, inserted on lateral margins of subapical area of subgenital plate. Female. Appearance is similar to that of male. Subgenital plate nearly trapezoidal, basal area broad, then narrowing, basal half with thin transverse folds, posterior margin subtruncate. Ovipositor thin and long, straight, dorsal and ventral margins almost parallel, apex broken. Tegmen: CuA forks near basal third into two veins, CuA1 and CuA2, anterior branch briefly fused with MA and then divides, subsequently divides near mid-length of the tegmen into two parallel branches, MP and CuA1, while the posterior branch (CuA2) undivided throughout. Coloration. Body light yellow. Inner margin of antennal socket black. Base and apex of scape, base of pedicel with dark brown spots. Eyes black, ocelli light red. Apical area of mandible black. Pronotum with dark brown rim, the midline with a broad longitudinal rosy stripe. Tegmen with rosy veins. Fore femur and tibia rosy as well as middle femur and tibia. femur and tibia.

Holotype: ♁, Taiyanghe, Puer, Yunnan, 30 July, 2022, coll. Yanhao Duan and Jie Su. Paratype: 1♁, Taiyanghe, Puer, Yunnan, 29 July, 2022, coll. Yanhao Duan and Jie Su. Other specimens: 1♁ 1♀, same data as paratype. Etymology. The name of the new species is derived from the processes on male tenth abdominal tergite stout, from Greek erromen - (stout). Discussion. The new species is similar to Homogryllacris obtusitubera Li, Dou & Shi, 2019 based on morphology of the processes on male tenth abdominal tergite, but it can be distinguished from the latter in the following: body obviously large, body length about twice as long as that of the latter species; posterior margin of male subgenital plate with a triangular notch; female subgenital plate is of almost equal length and width, posterior margin subtruncate. Furthermore, DNA sequencing was implemented of these two species based on COI, the genetic distance between them is more than 8% (unpublished). Hence, with a combination of morphological and molecular evidence, we regard it as a new species of Homogryllacris.
