9513480DFFBCFFC7FA9C1960FD5DF9DC.taxon	discussion	Remarks. P. yuani sp. n. is similar to Pteronemobius gifuensis Shiraki, 1911 in appearance, but the medium ocellus of P. yuani sp. n. is smaller than the lateral ocellus and the occiput has no stripes. Male genitalia of P. yuani sp. n. are relatively similar to Pteronemobius yezoensis Shiraki, 1911, but with the difference being that the size of the genitalia of P. yezoensis is significantly larger than that of P. yuani sp. n. On the back, the epiphallus median lobe of P. yezoensis is relatively thick and short.	en	Wang, Rui, Yuan, Wei, Zheng, Yan-Na, Gu, Jun-Jie, Ma, Li-Bin (2023): Pteronemobius yuani Ma & Wang sp. nov. and Metiochodes tianfuensis Ma, Yuan & Gu sp. nov., new species of Trigonidiidae from China (Orthoptera: Trigonidiidae; Trigonidiinae).

The Cu vein furcating many times: Cu vein basaly bifurcating into CuA (red color line) and CuP, the CuP basaly then bifurcating into CuPa (blue color line) and CuPb (purple color line), and the end of CuPa bifurcating into CuPaα and CuPaβ, next CuPaα divided into two branches, CuPaα 1 and CuPaα 2. In addition, the h vein connecting the veins of CuPaβ and CuPaα 2, and the c vein connecting the corners formed by CuPaβ and CuPb. The exposed part of the wing accounts for about 60 % of tegmen.

Body bright green when alive. Tegmina yellow green; wings light brown. Eyes green, with dark brown patterns.	en	Wang, Rui, Yuan, Wei, Zheng, Yan-Na, Gu, Jun-Jie, Ma, Li-Bin (2023): Pteronemobius yuani Ma & Wang sp. nov. and Metiochodes tianfuensis Ma, Yuan & Gu sp. nov., new species of Trigonidiidae from China (Orthoptera: Trigonidiidae; Trigonidiinae).

9513480DFFBEFFC1FA9C1CC2FE7DF848.taxon	discussion	Remarks. M. tianfuensis is similar to Emerasoma curvicerca (He, et al., 2020) in appearance, but the epiphallic M. tianfuensis is symmetrical. Secondly, M. tianfuensis is similar to Metiochodes truncatus (Li, et al., 2010) in male genitalia, but differ in the body color bright green and the genitalia of M. tianfuensis are generally thicker, epiphallic lateral lobe has spines.	en	Wang, Rui, Yuan, Wei, Zheng, Yan-Na, Gu, Jun-Jie, Ma, Li-Bin (2023): Pteronemobius yuani Ma & Wang sp. nov. and Metiochodes tianfuensis Ma, Yuan & Gu sp. nov., new species of Trigonidiidae from China (Orthoptera: Trigonidiidae; Trigonidiinae).
