The specimens are collected from Miaoershan Natural Reserve of Guangxi Province. Type specimens are deposited in the Insect Specimen Room of Taohuaping Campus of College of Life Sciences of Hunan Normal University. 1. Longzhouacris miaoershanensis, sp. nov. (Figs.1～7) This new species is allied to Longzhouacris rufipennis You et Bi, but differs from the latter in: ① antennae with 23 segments, and middle segment 3.0～3.5 times as long as its width (♂); ② prozona of pronotum 2.2 times as long as metazona (♂); ③ lower kneelobe of hind femur squarish, and its apex right angle-shaped (♂); ④ apex of subgenital plate nearly flat (♂); ⑤ hind tibia dark greenish blue (♂,♀). This new species is also similar to Longzhouacris huanjiangensis Jiang et Zheng, but differs from the latter in: ① middle segment of antennae 3.0～3.5 times as long as width (♂); ② prozona of pronotum 2.2 times as long as metazona (♂); ③ lower kneelobe of hind femur squarish, and its apex right angled-shaped (♂); ④ posterior margin of epiproct acutely angled-shaped, and its longitudinal depression on the back of the apical half disappeared (♂); ⑤ frons grass green, antennae coral except 4～5 basal segments, the lower half of elytra coral and the upper half of that light reddish-yellow.

Holotype ♂, Guangxi: Xing'an County (Tizhiling of Miaoer Mountains), 750 m, 25°49′N, 110°25′E, 26-Ⅷ-2000, collected by Huang Jianhua. Paratypes 1♂4♀♀, same as holotype. 2. Caryanda miaoershana, sp. nov. (Figs.8～14) This new species is allied to Caryanda hunana Liu et Yin, but differs from the latter in: ① interspace between mesosternal lobes not very narrowed, its length 6(♂) and 1.5(♀) times as long as its minimum width; ② the widest of vertex in front of eyes 1.4 times its length; ③ body of male or female obviously smaller; ④ shape of epiphallus or phallic complex different. Length of body: ♂ 23.0 mm, ♀ 32.5 mm; Length of pronotum: ♂ 5.2 mm, ♀6.8 mm; Length of elytra: ♂ 4.0 mm, ♀ 4.6 mm; Length of hind femur: ♂ 14.1 mm, ♀ 17.5 mm. Holotype ♂, Guangxi: Xing'an County (Laoshanjie of Miaoer Mountains), 1400 m, 25°49′N, 110°25′E, 26-Ⅷ-2000, collected by Huang Jianhua. Paratype 1♀, same as holotype.
