03D387FB9259E714FF33C027FCE63EF4.taxon	diagnosis	Diagnosis. Dericorys albidula is clearly distinguished from D. tibialis and D. annulata by a combination of characters. It is significantly larger, being approximately 1.5 to 2.0 times the length of D. tibialis and D. annulata. The hind tibia exhibits two pale blue rings basally and a rose-red coloration terminally, while the tibial spines are rose-red at the base and blue at the tips.

03D387FB925CE712FF33C10EFC0D3EE3.taxon	diagnosis	Diagnosis. Thrinchus arenosus is similar to T. aralensis but can be distinguished by several key morphological characters. In lateral view, the prozona of T. arenosus is distinctly elevated and plate-like, whereas that of T. aralensis is only slightly raised. Additionally, the basal area of the hind wing is green-blue in T. arenosus but dark-blue in T. aralensis. The hind tibia spurs of T. arenosus are also notably longer.	en	Chen, Jian-Yu, Liu, Yu-Xian, Yang, Jin-Chen, Wang, Shao-Shan, Li, Xin-Jiang (2026): Two new records of grasshopper (Orthoptera: Acridoidea) in China.
