Description. The female is first described and differs from Homogryllacris brevipenna Du, Bian & Shi, 2016 in: the color patterns of dorsal surface of head and disc of pronotum; hind femora with 5 pairs of spines on ventral surface; dorsal surface of tibiae with 4 – 5 internal and 6 external spines; posterior margin of female subgenital plate widely rounded without median concavity ( Fig. 8G View FIGURE 8 ).

Measurements (mm). Female: BL 20.65, PL 5.05, HFL 11.39, TL 3.30, OvL 22.57.

Material examined. 1 female, Heiqiong Road, Kunming , Yunnan, July 21, 2023, coll. by Siyu Pang, Ting Luo and Qiu Yi .

Distribution. Yunnan (Kunming).

Discussion. The specimens from Heiqiong, Kunming, Yunnan ( Figs. 9 View FIGURE 9 , 10 View FIGURE 10 ) are very similar to holotype of Homogryllacris xishanensis Zhang, Liu & Bian, 2023 , we illustrate them as intraspecific variation of Homogryllacris xishanensis Zhang, Liu & Bian, 2023 . These specimens can be distinguished by: the black margins of disc in pronotum obviously widened at anterior and posterior margins forming 1 pair of black irregularity spots separately; median concavity of male subgenital plate wider and shallower, the lateral lobes with longer apices; posterior margin of female subgenital plate more regular with faintly concave in middle. The other information are as follows:

Measurements (mm). Male: BL 15.13, PL 4.01, HFL 8.59, TL 22.33; Female: BL 16.15 – 19.50, PL 3.63 – 4.50, HFL 9.61 – 9.92, TL 1.97 – 2.76, OvL 18.13 – 20.42.

Material examined. 1 male and 3 females, Heiqiong, Kunming , Yunnan, July 21, 2023, coll. by Siyu Pang and Ting Luo ; 2 females, Xishan, Kunming , Yunnan, July 20, 2023, coll. by Siyu Pang and Ting Luo .
