03804B32FFEEFFE2FF32FD53FDC3F810.taxon	etymology	Etymology. The name of this new species is derived from the posterior area of male subgenital plate posteriorly prolonged, the Greek “ mecyn- ” means prolonged.	en	Su, Jie, Wang, Tingting, Shi, Fuming (2025): One new species of the genus Acosmetura (Orthoptera: Tettigoniidae: Meconematinae) from Sichuan with description of the female of Xiphidiopsis (Euxiphidiopsis) spicula Su, An & Shi, 2023.

03804B32FFEEFFE2FF32FD53FDC3F810.taxon	discussion	Discussion. We collected numerous specimens of this new species on ferns and bamboos at altitudes above 2500 meters, where it predominantly inhabits low-growing vegetation. The male of this new species resembles Acosmetura longitubera Wang, Shi & Wang, 2018, but differs in the following: male cercus with a tooth on the inner surface near base, and genitalia bearing a pair of laminae that connected at base. The female is very distinct from other Acosmetura species in its significantly enlongated and slightly upcurved ovipositor.	en	Su, Jie, Wang, Tingting, Shi, Fuming (2025): One new species of the genus Acosmetura (Orthoptera: Tettigoniidae: Meconematinae) from Sichuan with description of the female of Xiphidiopsis (Euxiphidiopsis) spicula Su, An & Shi, 2023.
